Well, I guess if H.264 wins hands down even with 1/4 the bandwidth then I guess a direct comparison isn't really necessary... though I must admit, I haven't seen it as THAT radical.

I am pleasantly surprised by how much better - for me - that QT7/H.264 is compared to Sorenson 3 with some simple testing.

Oh, I totally agree the difference is there and obvious... I was just pointing out it's hard to make a real comparison when you encode to radically different bitrates. I always target the same bitrate for all clips in a test, so that the only variable is quality - otherwise if both quality and bitrate are variable it's pretty arbitrary.


Of course, if your H264 had both lower bitrate AND higher quality then it's obviously superior... you just don't know by how much.

I haven't done any extensive testing on other types of video - in this case the video was of parked buses - not much motion and no transitions.

Heheh, well yeah, selecting good source and selecting proper encoding options is important, otherwise you have to heavily qualify your choices (as I did in my H264 color test) to cover your butt.
