Another great post over at Jake Ludington’s blog, how to use freely available ffmpegX to convert video files into Flash video for web use. He’s even got instructions on how to embed the videos in a web page using Joroen Wijering’s flash player. Did I mention that the ffmpegX software is free?
Windows fmpeg users should check out SUPER, a gui frontend to ffmpeg, mencoder, and various other command-line tools.
