Appreciate the help, but I'm specifically looking to encode for embedded Flash using the H.264 codec. Premiere Pro, near as I can tell, does not have an H.264 codec for Flash. I already encode Flash using the Spark or On2 codecs built into Sorenson, and those work nicely, and I also have a native H.264 codec for Quicktime built into Sorenson, but the H.264 standard is a far more advanced codec, and I'm told that there is a way to encode Flash using H.264.

What I'm specifically trying to determine is whether a standard Flash player will be able to play back an .flv encoded with H.264. I'm not concerned about the playing computer's specs, since practically any computer can play Flash provided the bitrate of the video stream is lower than the download rate. It's specifically a codec and player compatibilty issue I'm trying to get resolved.
