Maybe we have wires crossed, are you using quicktime, ffmpeg or ffmpegX GUI? I was on about ffmpegX, which Im guessing isnt what you are referring to? If it is what you were talking about then Im even more confused because it doesnt use quicktime for encoding as far as I know.
Anyway thanks for the high-res h264 sample. It is nice quality, but you really need to deinterlace it because of the higher resolution youve used, on that clip the interlace effects spoil the better quality whenever theres movement. From what I recall quicktime has no deinterlace feature that actually works properly when creating h264 etc, but ffmpegX does have a deinterlace option.
