How to upload a video to YouTube and ensure it is made available as WebM

As of a couple weeks ago, you can now ensure that YouTube will make any video you upload available in WebMthrough their HTML5 interface, by uploading it as WebM and not using the "annotations" or "display ads" options. This guide will help you do that.

You can also get embedded videos to automatically use WebM, in supporting browsers, by adding "html5=1" to the URL of the iframe in your embedding code. (You can see an example of this on adblockplus.org) If you are linking to the video on YouTube, you can also force HTML5 support by adding that parameter to the link you provide.

Unfortunately, viewers who visit the YouTube website without going via such a link will still see your videos in Flash unless they themselves have opted into YouTube's HTML5 beta. Instructions for opting in are at http://www.youtube.com/html5 -- be sure to point people there when promoting your videos.

Here we present instructions for using VLC version 1.1.2 to convert any common video format to WebM. VLC runs on GNU/Linux, Windows and Mac OS. We presume the same recipe will work on future VLC versions; please leave a note on the talk page here if you have any trouble. On GNU/Linux you can also do this job with Transmageddon, Arista, PiTiVi or FFMPEG.

Prerequisites:

  • VLC 1.1.0 and greater
  • A video to convert

Instructions

  • Option: You may select "Display the output" to play the video as it converts it, but that may slow things down significantly.

  • If you are converting an interlaced video file, for example from a digital camcorder with a resolution like 1080i rather than 1080p, select "Deinterlace", otherwise ignore this.
  • Option: Advanced options for quality and other settings are available if you click the button with the icon of tools to edit the selected profile.

9. Click start to begin transcoding, and you should see the media progress bar and the time in the lower-right corner indicate how far it is.

10. Open the resulting WebM file to verify that it works.

11. Upload to YouTube

Make sure not to use any of the 'annotations', 'display ads' or 'audioswap' options.

12. Change links or embedding code to request HTML5

To get YouTube to serve the video as WebM to supporting browsers, even if they haven't opted in to the YouTube HTML5 beta, add "?html5=1" to the end of the src parameter in your <iframe>, or to the end of your link to YouTube. (If the link already has parameters, the ? needs to be an & instead.)

E.g., for an embed:
