FFmpeg is an open source command line utility that actually serves as the engine for the applications noted above. Let’s learn how to convert MP4 to WebM using FFmpeg for Mac or Linux. Both are good options if you just want something quick and easy. Miro does have batch converting, but it doesn’t offer total control over the conversion settings and it can be slow. However, they both have some limitations: Firefogg works well, but it doesn’t have batch converting. There are two good applications that can do these conversions quickly for you: the Firefogg Firefox extension and the Miro Video Converter. You need a tool to convert those MP4 files to WebM. Most video applications can export videos in the MP4 format, but they usually can’t export in the WebM format. For Chrome, IE9/10, and Safari, you need MP4 video files, and for Firefox and Opera, you need WebM files. HTML5 video is great, but to support all the modern browsers (Chrome, Safari, Firefox, Opera, IE9/10), you need to serve two versions of your video files. SublimeVideo provides a clean and flexible player that automatically picks up the video and also handles playing it via Flash when a browser doesn’t support HTML5.

You add the player via one line of JavaScript and you can write native HTML5 video syntax. Unlike YouTube or Vimeo, SublimeVideo lets us host and serve our own video files and keep them white-label. We use the excellent SublimeVideo player to power the videos. Here at The Theme Foundry we sell WordPress templates and host quite a few tutorial videos over in the Help Center.
