I want to put a portion of a video that I edited together onto the web. Edited in FCP, compressing using QT Pro. After playing around with numerous different compression, all looking like crap, I finally decided that I'd download a trailer from Apple.com/trailers, and duplicate those settings. I matched the settings as best I could, and even though I'm compressing at a lower resolution 320x186 (compared to 480x272) at similar bit rates of Sorenson 3, I'm still getting very blocky compressed video, and certainly nothing like the video I've downloaded. I've played with setting the keyframe interval with varied success, but again nothing like what the downloaded movie looks like. Do they have special compression software that uses a different Sorenson 3 than QT Pro converts to? I'm starting to get exceedingly frustrated!
