Ken, I'm currently working on an HTML5 video project. It is not in production yet, but inline are a few notes on what I'm doing right now and think will work. > * Which formats do you typically include? Right now I'm only creating an MP4 and WebM. Once Firefox and Opera support H264, I'll probably drop WebM. The Flash fallback uses the same MP4, and fills the gap for older browsers. I also provide a download link to the MP4 just in case no in-browser player will work. I'm currently using the MediaElements.js player in order to have a similar look to the player even with Flash fallback and a single JS API. You may look at this comparison of players to see what you like: http://praegnanz.de/html5video/ > * How do you generate videos in those formats? To create the MP4 I use HandBrakeCLI. For WebM, I'm using ffmpeg. > * What kind of workflow for file creation makes this process manageable. I've just written a script which takes source video, adds a common credits snippet to each video, and then wraps system calls to convert to MP4 and WebM. The script also takes the first frame of the video to create a poster image. I'd be interested to hear what others are doing for video delivery. Jason
