I don't know if youtube will accept prores, and they have a file size limitation, I think.
Try a full quality h264 (using the apple preset: formats: quicktime in compressor). If it's within the file size limitation, the quality's will be pretty good.
one more thing. prores is actually compressed. Great quality but compressed.
