| − | As of a couple weeks ago, you can now ensure that [https://groups.google.com/a/webmproject.org/group/webm-discuss/browse_thread/thread/39aea2c0aebaefa3 YouTube will make any video you upload available in WebM]through 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 [http://adblockplus.org/en/ 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.

Instructions for opting in are at http://www.youtube.com/html5 -- be sure to point people there when promoting your videos.
