Note that if you're using ffmpeg (which seems to be popular for Flash video encoding), you have to be very very careful with encoding settings because it uses rather bizarre defaults for x264, forcing you to re-specify all the existing ones to get it to work ideally. Fortunately, there's useful guides on that too: http://ffmpeg.x264.googlepages.com/mapping http://ffmpeg.x264.googlepages.com/mapping http://rob.opendot.cl/index.php/useful-stuff/ffmpeg-x264-encoding-guide/ http://rob.opendot.cl/index.php/useful-stuff/ffmpeg-x264-enc... The first link is useful even if you're not using ffmpeg, since it has a relatively good explanation for what most of the options do. And if you still need more quality, drop by our IRC.
