Video Embed & Thumbnail Generator WordPress Plugin

In a future update (v4.7) this plugin will be changing its name to “Videopack” and removing old video players StrobeMediaPlayback and JW Player 6 that haven’t been supported for several years. Freemius will also be integrated on an opt-in basis to allow premium add-ons. More info in the support forum.

A plugin for the WordPress visual editor to make embedding videos, generating thumbnails, and encoding HTML5-compliant files a little bit easier.

Download from WordPress


  1. Upload the entire video-embed-thumbnail-generator folder to the /wp-content/plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Make sure you have all your MIME types configured correctly. Many servers don’t have .mp4, .m4v, .ogv configured, and even more don’t have .webm. There are a number of ways to do this. In your public_html directory you can edit your .htaccess file and add the following lines:
    AddType video/ogg .ogv
    AddType video/mp4 .mp4
    AddType video/mp4 .m4v
    AddType video/webm .webm


    AddType video/mp4 .mov

    will help with IE playback of .mov files but could interfere with other QuickTime players.
    Or use your web host’s configuration panel (cpanel, etc) to add custom MIME types.

Just click the Add Media button to get started:

This plugin adds several fields to any video uploaded to the WordPress Media Library. Just choose a few options, make thumbnails, click “Insert into Post” and you’ll get a shortcode in the post editor that will embed a flexible, responsive HTML5 video player with Flash fallback for unsupported browsers.

Sample video:


Sample gallery:

[KGVID gallery="true" gallery_include="2596,2750,2721,2719,2634,2591" gallery_orderby="rand" gallery_thumb="226"][/KGVID]


You have the option to use a few different video players:

  • Video.js (files are included with the plugin)
  • The WordPress default player using MediaElement.js, which was introduced in WordPress version 3.6
  • JW Player 6 (if their old, discontinued plugin is already installed. This plugin does not work with JW Player 7 yet.)
  • Adobe’s Strobe Media Playback Flash player (deprecated)

The Strobe Media Playback option hasn’t been updated since 2011 and is not recommended, but I’m keeping it around for longtime users of this plugin who don’t want to change. Most features of the plugin will work when using Strobe Media Playback, but new features will not be tested with it. Selecting Strobe Media Playback will default to a Flash video player if you’re using a Flash-compatible file (flv, f4v, mp4, mov, or m4v). Otherwise it will use the Video.js player as a fallback.

No matter which player you use, the video will responsively resize to fit the container it’s in. There is no need to use FitVids.js and in fact FitVids.js will break playback for some players. If you provide multiple H.264 resolutions, the plugin can automatically select the one closest to the size of the player or a resolution of your choice, and provide a button for users to select the resolution manually. If you have Google Analytics set up on your site, the plugin will automatically send Google Analytics Events when users start, reach 25%, 50%, 75%, and complete watching your videos.

You can also use the plugin to create a popup video gallery. The shortcode uses options similar to the WordPress image gallery shortcode. In its simplest form use the code [KGVID gallery="true"] to create a gallery of all videos attached to the post. Thumbnail size and video popup size can be set on the plugin settings page or in the shortcode. To make a custom gallery that includes videos that aren't attached to the current post you'll need to determine the video's ID, which is shown under the Video Stats section when viewing the attachment. Switch the "insert" option from "Single Video" to "Video Gallery" and you'll get a number of additional options (all of which are optional). Add a comma-separated list of video IDs in the "Include" field to create a gallery manually. Note: the "Create Gallery" section of the Add Media window is a built-in WordPress function and is only for making image galleries.

If your video can be played natively in your browser, or if you have FFMPEG or LIBAV installed on your server, you can generate thumbnails from your video. Using either the "Generate" or "Randomize" buttons will create an array to choose from. The "Generate" button will always generate thumbnails from the same frames of your video, evenly spaced. If you don't like them, you can randomize the results with the "Randomize" button. If you want to see the first frame of the video, check the "Force 1st Frame Thumbnail" button. After creating an array of thumbnails you can save them all using the "Save all thumbnails" button.

If you know which frame you want to use for your thumbnail, click "Choose from video..." to select it from the video. This will only work for videos that can be played natively in your browser. If you want really fine control you can enter timecode in the "Thumbnail timecode" field. Use mm:ss format. Use decimals to approximate frames. For example, 23.5 will generate a thumbnail halfway between the 23rd and 24th seconds in the video. 02:23.25 would be one quarter of the way between the 143rd and 144th seconds. You can generate as many or as few as you need (up to 99 at a time).

After you select a thumbnail it will be registered in the WordPress Media Library and added to the video's attachments. Unused thumbnails will be deleted.

In the plugin settings you can set the default maximum video width and height based on the dimensions of your particular template and those values will be filled in when you open the window. If you generate thumbnails, the video display dimensions will be adjusted automatically to match the size and aspect ratio of the video file. You can make further adjustments if you want. There are options to always fill the width of the template or to always set videos to the maximum width setting regardless of their resolution.

If enabled in the plugin settings, Facebook, Twitter, and video search engine metadata will be generated for your videos. If your site supports https, your videos can play directly in the Facebook timeline or on Twitter. Twitter requires whitelisting for each domain that provides player cards so you will be required to request whitelisting using the Twitter Card Validator tool. Once you've installed the plugin and enabled the Twitter Cards setting, go to the Twitter Card Validator, enter a secure URL from your site that has a video embedded using this plugin, click "Preview card" and you'll probably see a warning that your site isn't whitelisted. Request whitelisting and Twitter should approve you fairly quickly. Enabling the Facebook or Twitter metadata options will override Jetpack's corresponding metadata whenever a video is embedded on the page. However, your theme or SEO plugins might generate their own metadata that could conflict with this plugin's.

You can add subtitle and caption tracks by choosing properly formatted WebVTT files from the media library or entering a URL directly. Enter the two-letter language code and the label text that will be shown to users. Enabling the "default" option will turn the text track on when the page loads. The WordPress default player does not differentiate between captions and subtitles, but Video.js will show a different icon depending on the selection.

I highly recommend using Handbrake to make a file with H.264 video and AAC audio in an MP4 container before uploading. If you're encoding with Handbrake make sure that "Web Optimized" is checked. Using Apple's Compressor, the "Streaming" setting should be "Fast Start" (not Fast Start - Compressed Header).

The plugin can use FFMPEG or LIBAV to encode videos and make thumbnails if you have one of them installed on your server. You can choose to generate thumbnails and additional video formats automatically whenever a new video is uploaded to the media library, and there are buttons to generate thumbnails and additional video formats for every video already in the media library. If you want most videos to be re-encoded and replaced with a particular format but sometimes want to keep the original video, you can add the suffix '-noreplace' (awesomevid-noreplace.mp4) to your filename and the uploaded video will not be replaced. Other automatic formats will still encode.

By default the plugin looks for FFMPEG in /usr/local/bin but if the application is installed in a different place on your server, you can point it to the correct place in the plugin settings. Users running WordPress on Windows servers should try using Linux-style paths (with forward slashes instead of backslashes and a forward slash / instead of C:). Multisite Super Admins must set the FFMPEG path in the Network settings page which will enable FFMPEG throughout the network.

If you have the proper libraries installed on your server, you can choose to replace your uploaded video with your preferred format, and generate as many as seven additional formats depending on your original source. 1080p, 720p, and 360p H.264, same resolution WEBM (VP9 or VP8) and OGV, and a custom format. Different browsers have different playback capabilities. Most desktop browsers can play H.264, and all modern mobile devices can play at least 360p H.264. If you create multiple H.264 resolutions, the highest resolution supported by the device will be served up automatically. The plugin will not upconvert your video, so if you upload a 720p video, it will not waste your time creating a 1080p version. There was a time when it seemed like a good idea to provide OGV or WEBM for some desktop browsers, but Firefox supports native H.264 playback in most operating systems now. I no longer recommend encoding OGV or WEBM unless you're making an open source principled stand against H.264. However, your needs may vary. VP9 WEBM is a next-generation codec not supported by many browsers, but it can make videos much smaller while still retaining quality.

The files will encode in the background and will take some time to complete, depending on your server setup and the length and size of your video. VP9 encoding will take much longer than any other format. The plugin adds a Video Encode Queue menu to the Tools menu. You will see encoding progress, the option to cancel an encoding job, and you should get an error message if something goes wrong. Users on Windows servers may get inconsistent results with the encoding queue.


Encoded H.264 files can be fixed for streaming using "movflags faststart" introduced in recent versions of FFMPEG/LIBAV, or qt-faststart or MP4Box if you have one of them installed on your server and select it in the plugin settings. Without one of these options enabled, FFMPEG/LIBAV will place moov atoms at the end of H.264 encoded files, which in some cases forces the entire file to download before playback can start.

If you want to make OGV, WEBM, or H.264 files available and can't use the FFMPEG encode button, you can upload your own files to the same directory as the original and the plugin will automatically find them. For example, if your main file is awesomevid.mp4, the plugin will look for awesomevid-1080.mp4, awesomevid-720.mp4, awesomevid-360.mp4, awesomevid.webm, awesomevid-vp9.webm, awesomevid.ogv, and awesomevid-custom.mp4 as well. If your videos don't conform to that naming structure, you can manually assign them from the media library. No matter what format your original video is, you can use it in the shortcode and the plugin will attempt to find all compatible formats related to it. For example, you might have an AVI called awesomevid.avi which is not compatible with any browser, but if you have other formats encoded already, [KGVID][/KGVID] will ignore the incompatible AVI file, but find those other formats and embed them.

If you want to make it easier for users to save your videos to their computers, you can choose to include a link by checking the "Generate Download Link Below Video" button.

Sometimes for various reasons you might need to embed video files that are not saved in the WordPress Media Library. Maybe your file is too large to upload through the media upload form (if it is, I suggest the excellent "Add From Server" plugin), or maybe it's hosted on another server. Either way, you can use the tab "Embed Video From URL" in the Add Media window. Just enter the Video URL manually, and all other steps are the same as the Media Library options. The plugin will look for alternate encoded files in the same directory as the original, but this takes a long time when the video is on another server so it will only check for them once.

Once you've filled in all your options, click "Insert into Post" and you'll get a shortcode in the visual editor like this

To embed videos on other sites you can use an iframe like this

<iframe src='[enable]=true' frameborder='0' scrolling='no' width='640' height='360'></iframe>

If you enable oEmbed provider data in the plugin settings, the URL of a post with a video shortcode in it or the URL of the video's attachment page will be converted to an embedded video on sites that allow oEmbed discovery. For example is the URL for this plugin on my website, but it has the oEmbed header for the video embedded in it so the URL will be converted to an embedded video on sites with oEmbed discovery enabled. WordPress limits oEmbed providers to an internal whitelist for security reasons. This plugin has an option to enable oEmbed discovery for users with the unfiltered_html capability.

The JW Player 6 plugin has been removed from the WordPress plugin repository and JW Player 7 uses a very different system for embedding videos. JW Player 7 support is not available in this plugin yet. The Strobe Media Playback option hasn't been updated since 2011 and is not recommended, but I'm keeping it around for longtime users of this plugin who don't want to change. Most features of the plugin will work when using Strobe Media Playback, but new features will not be tested with it. Selecting Strobe Media Playback will default to a Flash video player if you're using a Flash-compatible file (flv, f4v, mp4, mov, or m4v). Otherwise it will use the Video.js player as a fallback.

If you want to further modify the way the video player works, you can add the following options inside the KGVID tag. These will override anything you've set in the plugin settings

  • id="xxx" video attachment ID (instead of using a URL).
  • videos="x" number of attached videos to display if no URL or id is given.
  • orderby="menu_order/title/post_date/rand/ID" criteria for sorting attached videos if no URL or ID is given.
  • order="ASC/DESC" sort order.

  • track_label="Track Label" text that will be shown to the user when selecting the track.
  • track_default="true/false" track is enabled by default.

These options will only affect Video.js playback

  • skin="example-css-class" Completely change the look of the video player. Instructions here.
  • nativecontrolsfortouch="true/false disable Video.js styling and show the built-in video controls on mobile devices. This will disable the resolution selection button.

These options will only affect Flash playback in Strobe Media Playback video elements. They will have no effect on HTML5 or Video.js playback.

  • autohide="true/false" specify whether to autohide the control bar after a few seconds.
  • playbutton="true/false" turns the big play button overlay in the middle of the video on or off.
  • streamtype="live/recorded/DVR" I honestly don't know what this is for.
  • scalemode="letterbox/none/stretch/zoom" If the video display size isn't the same as the video file, this determines how the video will be scaled.
  • backgroundcolor="#rrggbb" set the background color to whatever hex code you want.

These options are available for video galleries (options work the same as standard WordPress image galleries)

  • gallery_thumb="xxx" width in pixels to display gallery thumbnails.
  • gallery_exclude="15" comma separated video attachment IDs. Excludes the videos from the gallery.
  • gallery_include="65" comma separated video attachment IDs. Includes only these videos in the gallery. Please note that include and exclude cannot be used together.
  • gallery_orderby="menu_order/title/post_date/rand/ID" criteria for sorting the gallery.
  • gallery_order="ASC/DESC" sort order.
  • gallery_id="241" post ID to display a gallery made up of videos associated with a different post.
  • gallery_end="close/next" either close the pop-up or start playing the next video when the current video finishes playing.
  • gallery_per_page="xx" or"false" to disable pagination. Number of video thumbnails to show on each gallery page.
  • gallery_title="true/false" display the title overlay on gallery thumbnails.

For example

[KGVID autohide="false" loop="true" autoplay="true" poster="" width="720" height="404"][/KGVID]

These options can be added to the URL to further customize playback

Using the `kgvid_video_embed` query string any of the following options will modify playback: auto_res, autoplay, default_res, fullwidth, height, mute, nativecontrolsfortouch, pixel_ratio, resize, set_volume, start, width

Example:[start]=29&kgvid_video_embed[autoplay]=true autoplays the embedded video and starts 29 seconds in.

Developing on

I'm not really a software developer. I'm just a film editor with some time on his hands who wanted to post video for clients and wasn't happy with the current state of any available software. But I want to really make this thing work, so please help me out by posting your feedback on Github or my WordPress support forum. I do not offer free email support.


Why doesn't my video play?

Most of the time your video doesn't play because it's not encoded in the right format. Videos have containers like mp4, mov, ogv, mkv, flv, etc and within those containers there are video and audio codecs like H.264, MPEG-4, VP8, etc. The best option for this plugin is an mp4 container with H.264 video and AAC audio. It's confusing, but there is a codec usually identified simply as "MPEG-4" of "MPEG-4 Visual" which is not the same thing as H.264 even if it's in an mp4 container. mp4s with MPEG-4 video will not play in most browsers, and if you don't use AAC audio you won't get any audio. I highly recommend using Handbrake to make a file with H.264 video and AAC audio in an MP4 container.

Use MediaInfo to get really detailed information about your media files.

If your theme loads FitVids.js, it will break playback in Firefox. If you can figure out how to prevent your theme from loading FitVids.js you will not miss it.

Why does my video have to download completely before it starts playing?

mp4/m4v/mov files have something called a moov atom that gives the video player information about the content of the video (dimensions, duration, codecs, etc). Depending on the program you used to make your video, the moov atom can be at the beginning or the end of the file. Most video players will wait until they find the moov atom before starting playback. Otherwise it doesn't know how to display the information it's downloading. If it's at the beginning of the file, playback starts very soon after the user hits the play button. If it's at the end of the file, the whole video has to download before playback starts.

There are a number of ways to fix this problem. Most video encoding programs have an option like "Web optimized," "Streaming," "Fast start," or "Progressive download." Try to find and enable that option in your program. If you can't do that, there are programs designed to move the moov atom to the head of the file. Try QTIndexSwapperfor Adobe Air (cross platform), MP4 Faststart for Windows, or QTFastStart for Mac.

FFMPEG puts the moov atom at the end of the file, so this can be a problem. The plugin will fix this problem on newly encoded H.264 videos if you have a recent version of FFMPEG and enable the "movflags faststart" option in the plugin settings or if you have qt-faststart or MP4Box installed on your server.

Why doesn't this work with YouTube?

WordPress already has a built-in system for embedding videos from YouTube, Vimeo, Dailymotion, etc. Just put the URL into your post and WordPress will automatically convert it to an embedded video using oEmbed. You don't need this plugin to do that. If you're trying to generate new thumbnails from YouTube videos, I'm not going to risk Google's wrath by providing that functionality. I'm not even sure I could figure out how to do it anyway.

If you just want to change the skin or thumbnail of a YouTube video, use JW Player.

I'm getting an error message "FFMPEG not found at /usr/local/bin/. You can embed existing videos, but video thumbnail generation and Mobile/HTML5 video encoding is not possible without FFMPEG."

First off, don't panic.

This plugin can use FFMPEG or LIBAV to make thumbnails and create alternate video formats. Unfortunately most servers don't have FFMPEG installed and most shared hosting plans don't allow you to install FFMPEG because of the system resources it requires. You're getting this error message because you don't have FFMPEG installed in the most common directory. If you know you have FFMPEG installed on your server, you'll need to find the actual path to the program and enter it in the plugin settings field Path to applications on server

Most of the features of the plugin will work without FFMPEG. You can generate embed shortcodes for your videos and make thumbnails on any host because that part of the plugin is JavaScript running in your browser. But without FFMPEG you won't be able to automatically generate thumbnails or encode alternate formats on the server. If you don't have your own VPS or dedicated server, Dreamhost is one of the few shared hosts I know of that has FFMPEG installed and available for users.

How can I encode videos in directories protected by .htaccess passwords?

Enter the username & password in the plugin settings "FFMPEG Settings" tab, or use the "Embed from URL" tab and enter the URL in this format in the Video URL field.

4.1.3 – May 25, 2013

  • Updated Video.js to version 4.0.2 which is supposed to solve IE play-button loading issues.
  • Added option to show image at end of video in Video.js player (similar to the feature already available in Strobe Media Playback).
  • Fixed bug that ignored gallery_id setting in gallery shortcodes and was preventinggallery_include setting for videos that are not children of the current post.
  • Brought download link into shortcode rather than old method of inserting it into the post as text below the shortcode.
  • Automatically adjust pop-up gallery window height to display captions, view counts, and download links.
  • Rolled back responsive video resize method. Only the width of the immediate container will be used to calculate the correct size.
  • For very small videos, Video.js controls are now selectively removed as the width drops below 260 pixels to prevent them from dropping outside of the video window.

4.1.2 - May 23, 2013

  • Changed check for FFMPEG to use the H.264 sample video as input to avoid any PNG-related red herrings.
  • Added -f mjpeg to thumbnail-generating command to maintain compatibility with versions of FFMPEG that can't figure it out on their own.

4.1.1 - May 21, 2013

  • Removed second argument from json_encode() which caused video setup & resizing features to fail when servers were running PHP 5.2.

4.1 - May 19, 2013

  • Updated Video.js to version 4.0 and created a new skin that approximates the old one. Older versions of Video.js had some security holes, so this update is highly recommended.
  • Significantly reduced inline JavaScript generated by the plugin.
  • Fixed bug that disabled Strobe Media Playback player and caused "TypeError: Error #1034" messages, particularly in Internet Explorer.

  • Added support for AAC library libfdk_aac.
  • Adjusted embedded video and gallery CSS to account for colored backgrounds.
  • Renamed "Poster image" plugin setting to "Default thumbnail"
  • Removed post meta box below post editing window until I can work out a way to generate them without disabling video encode status monitoring in media modal popup when the same video is already in the post edit window.
  • Replaced deprecated ereg PHP function with preg_match and used a more precise regular expression when determining the height and width of videos.

4.0.3 - May 01, 2013

  • Fixed bug that caused video control text to display below videos on iPhones.
  • Changed method for saving video plays to the database. Now more secure and accurate.

4.0.2 - April 25, 2013

4.0.1 - April 23, 2013

  • Added options to display video title and embed code overlays on video player, and captions and view counts below videos.
  • Added option to filter your theme's video attachment page template to display the video instead of WordPress's default behavior of just showing the title of the video. For backwards compatibility retained old method of completely replacing the video attachment template with a video player.
  • Redesigned settings page to save using AJAX, and added a sample video player so changes are seen immediately.
  • Added iframe method to embed your videos on other websites.
  • Additional video formats encoded by the plugin are now added to the WordPress database as video attachments. To avoid a Russian nesting doll scenario these child attachments do not have the fields for creating thumbnails and encoding additional formats.
  • Changed encoded H.264 extensions from .m4v to .mp4 to increase compatibility with WordPress 3.6's new video capabilities. Existing M4V files will still work.
  • Checks only one time for alternate video sources when videos are embedded from other servers. This should speed up page load times considerably.
  • Added ability to rotate and replace the original file for videos recorded vertically on cell phones.
  • Added post meta box to posts with embedded videos that lists alternate formats found for each video.
  • Added option to set a post's featured image to the most recently generated thumbnail, and a button to set all previously generated thumbnails as featured images.
  • Added option to save generated thumbnails as children of either the video or the post the video is attached to, and a button to convert all thumbnails to the chosen hierarchy.
  • Added option to delete associated thumbnails and additional encoded video formats when original video attachment is deleted.
  • Added backwards compatibility for WordPress versions 3.2 and above.
  • If Strobe Media Playback player is selected, the Video.js player is used in situations where Flash doesn't work (webm, ogg playback) instead of the ugly default browser players.
  • Added watermark, view counts, volume attribute, and Google Analytics event tracking when using Strobe Media Playback player.
  • Added alignment option to center or right-justify videos.
  • Revised video player setup to properly resize the player if the containing DIV is smaller than the video, and resize again if the window size changes (or orientation changes on Android).
  • No matter which player is selected, iOS now displays the built-in controls so AirPlay works.
  • Added videoobject markup for improved SEO.
  • Fixed FLV embedding with Video.js player and improved selection of embedded formats for Strobe Media Playback.
  • Adjusted video gallery CSS and added a play button overlay to gallery thumbnails.
  • Adjusted watermark and Video.js play button CSS so the overlays don't overwhelm small videos.
  • Set Video.js controls to fade out on autoplay and on iOS, without having to mouseover the video.
  • Fixed endless "loading" spinner shown at the end of videos in some browsers in Video.js player.
  • Clicking "Insert into post" immediately after upload without changing any options now inserts shortcode instead of just the title of the video.
  • Inserting shortcode without a thumbnail no longer attempts to save the nonexistent thumbnail. Thumbnail cleanup is handled better.
  • Fixed error message "array_key_exists() expects parameter 2 to be array" when shortcode didn't have attributes.
  • Escaped all shell commands for increased security.
  • Fixed bug that made "Encode" button disappear if all formats were checked.
  • Fixed missing argument for kgvid_clear_completed_queue() when scheduling cleanup.

  • Added deactivation hook to remove queue and scheduled queue cleanup on deactivation.
  • Added uninstall.php to remove settings from the database on uninstall.
  • Disabled "Delete Permanently" link while encoding is canceling.
  • Checked for escapeshellcmd. If it's disabled on the server, encoding can't start.
  • Fixed insert title and download link checkboxes. They will actually insert something now.
  • Changed method for determining if a video has been played or paused and played again, for counting purposes.
  • Fixed check for mime type when generating H.264 video encode checkboxes to avoid showing options for QuickTime files that are higher resolution than the original video.

  • Added Google Analytics event tracking for video plays (Video.js only)
  • Added ability to encode multiple H.264 video resolutions.

  • Added setting to turn on vpre flags for users with installed versions of FFMPEG old enough that libx264 requires vpre flags to operate.

    Alonso Castro says:

    Hi, I have a question regarding this plugin. Desire to generate thumbnail images of the videos embedded but I get the following message: EXEC PHP is disabled in settings. You can embed existing video, but video thumbnail generation and Mobile/HTML5 video encoding will not work. Contact your System Administrator to find out if you can enable EXEC.

    then in the plugin settings option gives the option to put the path of the video supposedly I want to generate the thumbnail image, in my case the video is at the root then I guess it would be something like: /usr/local/bin/ffmpeg-i/

    the video is: ebenpagan.mp4
    my website:
    my user: **deleted by Kyle for security**

    and again I get the following message: EXEC PHP is disabled in settings. You can embed existing video, but video thumbnail generation and Mobile/HTML5 video encoding will not work. Contact your System Administrator to find out if you can enable EXEC.

    what is the solution? Please urgent

    • Kyle
      Kyle says:

      Just like the error message says, your server has the EXEC PHP function disabled. Sometimes EXEC is disabled for security reasons and cannot be enabled. I have no ability to tell you how to enable EXEC on your server because I don’t know why it is disabled. If you can enable EXEC and you have FFMPEG installed on your server then you can make thumbnails. Most shared hosts don’t allow you to install FFMPEG.

    Laura says:

    Hi Kyle,

    I just upgraded to your most current version of this plugin. I checked off “overlay embed code,” but it’s not overlaying it. I’m wondering if one of my “Better WP Security” settings is blocking it. But I’m not sure which one that would be. Although I disabled the plugin and it still wouldn’t create the embed button at the top.

    Is there a way to generate the embed code without that feature checked? Where do I find what I would need to include in the string?

    Also, when I click on “Save Changes” at the bottom, it redirects me to a page not found. Not sure why.

    Thanks in advance for your help with this.


    • Laura
      Laura says:

      By the way, I input the URL for all my videos and posters when creating the initial code with your plugin.

    • Laura
      Laura says:

      Hi again Kyle. Just sending you an update and another question. I think I figured out that you can’t use the embed code feature unless the media is in the WP media library, and not pulled in directly from a URL. So I have it working that way. But now I have another issue. The studio press theme I use forces me to limit the width of my videos to no greater than 580. This cuts off the text for “XX Views” so it says “XX View..” with only the left one third of the “s”. Is there a way that I can adjust it so it doesn’t cut it off?

      • Kyle
        Kyle says:

        That is correct. You can’t embed videos outside of the WP Media Library.

        A 580 pixel width shouldn’t be a problem on its own. There must be something else going on. Can you post a link for your site so I can troubleshoot it?

      • Kyle
        Kyle says:

        Ok, I figured it out. The 100% width of the DIV below the video is extending the views text a few pixels beyond the bounds of the video. I’ll add it to the next update. You can fix it now by removing the line width: 100%; from the .kgvid_below_video class in the css/kgvid_styles.css file. The link to edit the file is wp-admin/plugin-editor.php?file=video-embed-thumbnail-generator/css/kgvid_styles.css&a=te&scrollto=1530

        • Laura
          Laura says:

          Mobile Safari Question. Hi again Kyle. Different topic. I have the embed code working on a client’s website, pulling the video from my website. But it’s pulling an image of my websites home page, instead of the video. It’s even clickable inside the video window frame. It doesn’t do it on iPhone Chrome, though. I’m on a 4GS still running iOS 5 (jailbroken, so I can’t upgrade yet). Any ideas on why it’s doing that?

          • Kyle
            Kyle says:

            I can’t replicate the problem on my own site. I also don’t have an actual iOS 5 device, but it seems to work in the iOS Simulator. Can you post a link to the site you’re having a problem on?

  3. Marek
    Marek says:

    Hi Kyle!

    I have just installed your plugin, but I miss the most important button: there is no “Insert into post” at all! :-/ It’s not even anywhere hidden, I’ve just checked it out.

    What went wrong during the installation??

    WordPress 3.5.2 + plugin 4.1.5

    Thank you a lot for any help 🙂


    • Marek
      Marek says:

      Problem solved!!! I was trying to get the embed-code from within the media-gallery, but I need to be writing an article and insert the video from there.

    • Kyle
      Kyle says:

      Yes, version 4.2.1 of Video.js will be included in the next version of the plugin, which I thought would be released yesterday but I found a nasty bug. It will be released soon I hope.

  4. Tino
    Tino says:

    Another Suggestion,

    Make an option to select resolution in “Replace original with H.264” for example : Full Res, 1080p, 720p & 480p or even user defined to control the space in video storage.

  5. Cyrus
    Cyrus says:

    I’ve been trying to get this to work on a .m4v file…no luck! I’m not using video.js, just the embed wordpress player which seems to work stand alone but once I try to use the featured video thumbnail generator the video just never shows up.

    • Kyle
      Kyle says:

      Thanks for the note Cyrus. You’ve uncovered an interesting quirk of the WordPress video shortcode that I wasn’t aware of. Even though an m4v is just an mp4 with a different name, the shortcode gets very confused if (as I do in the current version of the plugin) you write [video mp4=""] instead it has to be [video m4v=""]. I’ll work on a fix for this but in the meantime you have a couple options. You could rename your video file to mp4 before you upload it, or switch to the Video.js player.

      • Cyrus
        Cyrus says:

        Hmmm….i do see video m4v. That one works. I tried using this instead:
        [KGVID poster="" width="500" height="281"][/KGVID]

        This doesn’t seem to work on my site.but the mp4 example from ur site does

        • Kyle
          Kyle says:

          Yes, that shortcode doesn’t work because of a bug you’ve uncovered in version 4.2.5 of the plugin that is specific to using m4v videos with my plugin’s shortcode and the WordPress Default player. I’ve already written a fix for it, which you could apply yourself if you’re comfortable editing plugin files. You can find the changes on Github

          If you don’t want to edit the plugin yourself, I’ll release an update within a day or two. Or you can switch to the Video.js player or rename the file to mp4 and upload it again.

            • Cyrus
              Cyrus says:

              See the plugin update! Thanks! Another question. Does this plugin auto resize to mobile? I am trying to set the height and width to auto but it doesn’t resize when I shrink the browser window.

              • Kyle
                Kyle says:

                It is supposed to resize if you set the width and height to the largest values you ever want them to be. The video will then shrink to the size of its container. The video near the top of this page shrinks down when you make the window smaller, but James Firth has just pointed out in another comment that his videos aren’t resizing, so if you have the same problem can you post a link to a video that’s giving you trouble?

    • Kyle
      Kyle says:

      That’s odd. I don’t know why that would change with the 4.2.6 update. Can you post a link to a page with videos that aren’t resizing so I can troubleshoot the problem?

  6. Jen
    Jen says:

    Hello Kyle- Can you please help me figure out why the video I am using with your plugin is not sizing properly? I currently have this set up on a test url and there are two black bars on either side of the video when played. Also, I have the ‘endofvideooverlay’ set to the same jpeg image as the ‘poster’ setting but nothing happens after the video plays… it just goes to black.

    This is the actual code I have inside the widget box:
    [KGVID poster="" title="false" width="370" height="252" endofvideooverlay=""][/KGVID]

    • Kyle
      Kyle says:

      You’re using a WMV file, which shouldn’t play at all, but apparently MediaElement uses a Silverlight player in a pinch. Just to make things even more difficult, the WMV is encoded with non-square pixels. I would start by transcoding the WMV to an H.264 MP4 at 640×360.

      The end of video overlay doesn’t seem to work with the WordPress Default player when you’re using Silverlight playback. It probably doesn’t work with Flash either. I will look into making that work, but it might not be possible. It should work with Video.js currently.

  7. David Vietnam
    David Vietnam says:

    Hello Kyle, I feel a bit foolish given the technical level of questions posted here but when I play the video (.MP4), I only see a black box, can hear the audio fine but cannot see the images. I followed the install instructions and added the Mime type:

    MIME Type Extension(s) Remove
    User Defined MIME Types
    video/mp4 mp4 .m4v

    Unfortunately this has not solved the problem and I still cannot see the video.

    Please help 🙂

    • Kyle
      Kyle says:

      Your video uses the MPEG-4 video codec instead of H.264, which is the most compatible video format for the web. If you re-encode using H.264 it should work.

    • Kyle
      Kyle says:

      There’s not much you can do about the buffer size of an HTML5 video player. I wouldn’t be surprised if that changes in the future, but the browsers are in charge of the process as far as I can tell. 4.2GB is really large for a web video. I suggest re-encoding the video with a much lower bit rate. Unless it’s 1080p and well over an hour you can probably won’t sacrifice any picture quality.

  8. Laura
    Laura says:

    Hi Kyle, hope you had a great 2013! And that you’re looking forward to an even better 2014. I have a question about trying to pull a video created with your plugin through to LinkedIn. It would be awesome if there were a way to make your plugin “talk” to linked in (in a way that made it approved by them). If that’s not possible, I’m wondering if you have any insight on how to get LinkedIn to pull through the featured image from the post. Right now, I can add the URL of the post which has the video embedded and it will pick up the headline and body copy, but not the video or the featured image. I’ve tried adding the poster image as a featured image a couple different ways, but still no luck. Have you been doing any work on trying to get your plugin to talk to LinkedIn? I’d love any advice you might have on this. Thanks in advance!

    • Kyle
      Kyle says:

      I don’t really know how LinkedIn works. I know they use Open Graph, so you should make sure have Open Graph image tags on your page. The Facebook debugger is a good tool to find out what Open Graph tags are on your page: From my Googling just now it looks like LinkedIn caches pages, so you might have found a way to make it work but it was still showing you the first version that didn’t work. I wouldn’t hold my breath trying to get it to pull a video though. I haven’t seen any indication that anyone has done that. They only just added YouTube and Vimeo last year.

      • Laura
        Laura says:

        Thanks Kyle for getting back to me on this. I’ll look into it. I have another question on a different topic. Is there a way to view the number of times a video has been viewed without making it visible to the public? It would be awesome if there were some type of dashboard that logged the views per video. Any thoughts or ideas? Thanks!!

        • Kyle
          Kyle says:

          Yes. Every video has both “starts” and “complete views” logged whether you show the numbers to users or not. If you look at a video in the Media Library it’s right above the thumbnail generating section.

          • Laura
            Laura says:

            Thanks Kyle. Any chance you might one day add a feature to your plugin that would present both view metrics for all videos in a single window?

              • Laura
                Laura says:

                Hi Kyle. Thanks — and I do have Google Analytics. But if you could direct me to instructions on how to set it up and view video views, I’d be very appreciative. I’m only seeing page views on my reports. Thanks!!

                  Ah. It only works for videos in the WordPress database. It looks like your videos are not in the media library. Is that true?

                    It used to be true. I’ve started pulling all the vids into the WP library a couple months ago. So going forward, I guess I could use GA.

                    But I’d really just love a way to aggregate your standard view count data in report form. A list of all the video file titles and a total view count that I could paste into Excel. Would that even be do-able?

    Can the plugin be used with more than 1 video? It looks as though everything is set up for one video, then if I would want to upload another video, the settings would change and affect the first video.

    90% of plugins are unusable, partly because the author was unable or unwilling to explain how to use them. We spend hours trying to learn to use something the author could have explained in five minutes. We test a dozen plugins before getting one to work. Everyone’s time is wasted. Your video plugin is the most notable exception I’ve seen. I’ve only scanned your application notes, I’ll be giving them a going over today. They are one of the primary reasons I’ve settled on your plugin. They set your work apart. Thanks Kyle.

    Hi ツ can we do something for the Safari browser that can’t play Webm ? i have a lot of video in webm and i very like if the peoples eith safari can see it on my site ! thanks..

    • Kyle
      Kyle says:

      Yes, if you have FFMPEG installed on your server you can use my plugin to make H.264 versions of your existing webm videos. Or you can make them yourself and upload them to the same directories as the webms. My plugin will find them automatically.

    I am loving the plugin and it’s been super helpful. I am trying to have the overlay closed after the video ends. Been fiddling around a bit, but could not work it out yet.
    Any ideas? Thanks heaps

    • Kyle
      Kyle says:

      I’m actually in the process or re-writing the gallery system so any hacks I worked out for you would be obsolete pretty quickly. It might not be possible because the current release uses an iframe that probably would prevent any commands coming from the iframe taking over the main page. I think it will be a lot simpler using the new system I’m working on. I’ll see if I can integrate that option along with automatically switching to the next video.

      • fsmathias
        fsmathias says:

        Thanks for that quick reply. Good to hear that you are working on the plugin because it is just brilliant. I was also thinking of maybe triggering the overlay via css to disappear when the video ends. something like:

        player.on(‘ended’, function kgvid_play_end(){
        kgvid_video_counter(id, ‘end’);
        setTimeout(function() { jQuery(‘#video_’+id+’ > .vjs-loading-spinner’).hide(); }, 250);
        if ( video_vars.endOfVideoOverlay != “” ) {
        jQuery(‘#video_’+id+’ > .vjs-poster’).css({

        player.on(‘timeupdate’, kgvid_timeupdate);
        } = “absolute”; = “-2000px”;


        Interested in your thoughts about this approach.

          Kyle says:

          I used your idea for version 4.3, which was released last night. If you add gallery_end=”close” to the shortcode, the pop-up will close at the end of video playback.

    Hi! Thanks for a great plugin!
    QUESTION: How can we offer the user a TOGGLE between the multiple available resolutions of the video? Yuu mention that the player will detect if other resolutions are available and serve the best possible one to the device. BUT, what if we want to serve a DEFAULT resolution, and let the user TOGGLE to other available resolutions if wanted just like on Youtube?

    For instance, I am uploading three resolutions: file-360.mp4, file-480.mp4 , file-720.mp4. I would like file-360.mp4 to play by default, and have a toggle for the other two resolutions; so it would display: 360p (active), 480p available and 720p available.

    Is this possible? I saw something similar with the plugin JW Player…

    • Kyle
      Kyle says:

      You can use the JW Player in version 4.3 of this plugin as long as you have the JW Player plugin activated on your site. It allows you to switch between two resolutions with the “HD” button. Other than that, it’s not built in to any of the other video players. YouTube can do this, but they have a lot more money for development than I do.

      • martinperreault
        martinperreault says:

        Thank you Kyle for your reply. How many hours and how much of a monetary contribution would you need to implement this feature? I would be interested in seeing such feature…

        It is my understanding that your plugin already detects already detects available resolutions that are present in the folder, and will upgrade the playback to the appropriate resolution of the device. Would it be complicated for the plugin to scan the folder for other available resolutions, and offer the user the ability to choose which resolution to play?

        I am no programmer at all, so please forgive me for my ignorance. 😉

  15. martinperreault
    martinperreault says:

    From what I understand, the plugin detects best available resolutions for the device. I would like to know:

    A) What is the proper name formatting of the embedded file, and its available resolutions?
    ie.: I embed “video-480.mp4” , and the following files are also present in the folder: “vide-720.mp4”, and “video-1080.mp4”
    If I embed “video-480.mp4”, will the plugin look for the other two? Or will it look for “video-480-720.mp4” and “video-480-1080.mp4” ?
    In other words, must the original embedded video file name be “video.mp4” or “video-480.mp4” ?

    B) If three resolutions are available in the folder, which resolution will be automatically played on mobile devices?
    For instance: video-480.mp4, video-720.mp4 and video-1080.mp4 are present in the folder, and “video-480.mp4” is the file embedded in the code.
    – If I browse that post with an iPhone, which video will playback?
    – If I browse with a tablet, which version will playback?
    – If I browse with a PC, which version will playback?

      Sorry, one last question: Is it just me, or Version 4.3.1 broke the “Make Video Player Responsive” feature?
      The videos used to display responsively on my theme.
      After the update, the video don’t display with responsive… they automatically enlarge to the largest video size defined in the settings of the plugin.

      To test, I tried to embed a youtube video directly with WP embed feature, and added the plugin “Responsive Video Embeds” and the youtube video automatically became responsive and displayed at full width of my theme width, and didn’t become larger – as opposed to “Video Embed & Thumbnail Generator” which still displays the video too wide at its fullest sizes…

      • martinperreault
        martinperreault says:

        Sorry Kyle, I do not wish to spam your comments. But I thought you would like to know that after additional testing Version 4.3.1, I can confirm that “Video.js” option in “Video Embed & Thumbnail Generator” seems to be broken for the Responsive Option. Switching to option “Video Player: WordPress Default” fixes the responsiveness. Unfortuantely, the player is not as nice lloking as “video.js”.

        Thank you for your time.

        • Kyle
          Kyle says:

          Post a link to a video your site so I can see what the problem is. I can’t guess.

          The original embedded video file should be video.mp4.

          The HTML5 video element lists the possible sources in this order if they exist:


          It’s up to the browser to choose the first video from the list that it is able to play.

            Thanks for the reply Kyle!

            Here’s a link:

            To test, I added the following three clips:

            The original file (bianca-beauchamp_2014_forbidden-love-preview.mp4) is super low resolution 270. I did this on purpose to see if the player would pick up the other available resolutions. When I test both on PC and mobile and tablet, they all play the 270 resolution and they do not play 720 nor 480.

            You mention that the browser chooses the file to play.
            How does the browser choose?

            For instance, on a PC, the browser can easily play all resolutions. Which one does it choose to play? How does it make the decision for:

            Also, in your example. video.mp4 is what resolution?

            • Kyle
              Kyle says:

              The browser will pick the first video from the sources list that it is able to play. If the browser is able to play video.mp4, it will play video.mp4. If it can’t play video.mp4 it will try video-1080.mp4, then video-720.mp4 and further on the list until it finds a video that it can play. If it can’t find a format it can play (in your example, Firefox on a Mac would be unable to play any of the available MP4 formats) then the Flash player is loaded and the first MP4 in the sources list will be loaded in the Flash player.

              In my example video.mp4 is any resolution you want it to be. I would recommend making it your highest available resolution, but do whatever works for your workflow.

              The page you posted has a responsive video on it. If you want my help I’ll need to see the problem on a live website.

              You asked earlier about the cost to implement a button for resolution switching. I haven’t done any research into the issue, but off the top of my head my guess is it would take 2 solid weeks and I can’t guarantee I could get it to work with the Flash player. The difficult part is switching resolutions during playback without starting the video over from the beginning. Since I can’t control the way users encode their videos it could just cause more confusion. I develop the plugin in my free time and don’t work professionally as a programmer, but if I were to charge a fair rate for the work, I think it would be at least $4000.

                Thank you Kyle for your answer. I appreciate it, as I also appreciate the plugin you have developped.

                $4,000 is out of my budget at the moment. That being said, perhaps if you were interested in developping further your plugin in that direction, I’m sure MANY users would be ready to support a kickstarter project. By crowdfunding the development of the plugin, it could alleviate costs for users, and in return would guarantee a revenue for your time spent on the development.

                I have searched EVERYWHERE online for a WP plugin that can handle resolution switching for video playback in wordpress, and NONE are available. I have also seen a lot of posts online from users who are looking for such a plugin. There is JPLAYER that offers resolution switching, but Jplayer’s is complicated to use, and their wordpress plugin only supports HD button (and even that I could not get to work).

                What I’m trying to say is I think there is a demand for such a wordpress plugin. Someone motivated could easily finance it with Kickstarter. Is this something you’d be interested in doing?


                Regarding file playback, my last question is:
                why is it that if the encoded video.mp4 file is low resolution (say, 360), and the browser can play 720, why is the player not picking up the 720 resolution to playback on my site?

                You mention: “The page you posted has a responsive video on it. If you want my help I’ll need to see the problem on a live website.”

                I do not understand what it is eactly you need. That link is actually using your plugin to playback the video…

                  I am not at all sure that many users would like to fund development of the plugin. I’ve been doing this for 3.5 years and have received less than $400 in donations out of 180,000 downloads.

                  The browser doesn’t look for the highest resolution video it is capable of playing. It looks for the first video in the list of sources that it is capable of playing. My plugin lists video.mp4 first, so if the browser can play it, it plays video.mp4 regardless of the resolution. I don’t know how else to explain this. Maybe look at the HTML5 video specs?

                  You wrote earlier that the Video.js option broke responsive resizing. I asked for a link that demonstrated the problem because I can’t replicate it on my own sites. You linked to a video that uses the WordPress Default option and works perfectly. I would like to troubleshoot the Video.js issue you were having, but that’s hard to do if I can’t see the problem.

                    I’m sorry to hear about the low donation rate. That being said, in the case of kickstarter projects, it is pretty surprising sometimes how people can be generous when it comes to financing a project that offers specific benefits, as it would be the case with a project about a wp player offering a resolution switch. I beleive this type of project would gain good traction amongst wp blogs. Food for thought!

                    About the responsive problem, somehow the problem is gone now. I reverted to the js player, and it works fine. Dunno what happened. Sorry for the trouble.
