I have a video I want to upload to Youtube (made in iMovie 3.0.3). If I use Full Quality export on iMovie, the file is 1.34gb, which is out of the question. If I use the next best quality (CD rom), the video is 31mb, which looks okay on my computer, but it's frame rate was **** on Youtube. I'm not a video editor or anything, so iMovie's "Expert Export" options baffles me. What should I do in the expert export to have file that's smaller than a gigabyte, but will upload good on Youtube?
