With iMovie HD6, I exported my video to a MOV file, I send it to Youtube, the next morning, it has an error that the file cannot be converted. I tried it again, and it stop right after it finishes uploading (before processing). Then, I thought that is because it's on iMac G4, which is maybe causing the problem. Tried on another modern computer, still can't upload. Tried exporting the video in AVI and MP4. However, the quality is HORRIBLE and unwatchable. I'm trying to find a software, to convert the MOV in MP4. 100% free apps don't work with MOV. Only programs with 3-minutes or 300MB limitations can convert MOV files. I'm trying to upload a damn video since 3 days ago and this is getting on my nerves, so can somebody help me with this problem? Sorry if it's in the wrong forum.
