I have tried uploading directly from iMovie to YouTube using the preset and it looks absolutely horrendous. I have also tried exporting into NTSC quality and the "large" preset and they both still look terrible. The video I am using is imported DV from a Sony Handycam, it's not that great of camcorder but when I watched the videos on my TV it looked fine. It's real simple video too, just video of my friend talking. What is the root of this problem and how can I fix it?
