I have uploaded several of my vids to youtube with good compression and they look fine. However, the some films and films that open on black with white titles get completely messed up the first five seconds. Basically it is a scrambled grey screen until the good quality dissolves in. Has anybody else had a problem with this? Do you have a solution? I compressed with iMovie on my Powerbook Mac. I saved as MP4 with the correct settings. They play perfectly on my Quicktime. But the exact same vid on youtube get's messed up in the opening somehow.
