My digital camera records movies in a Quicktime codec called JPEG-photo. I think it's just a bunch of still JPEGs at 30fps. These videos play very smoothly and are crisp (at 640x480), but they're huge.... hundreds of MB each. I've tried converting them to MPEG-4 using iTunes 7.2's "Export to AppleTV" option, or converting to MPEG-4 (with or without H.264) using iSquint. Either way, they look horrible, even using the highest encoding quality in iSquint. The playback of the resulting files is choppy, and there's a noticeable loss in image quality. However, the files are about 10-20% of the original size, which is great. Is this the best I can expect from MPEG-4, or is there a way to get better picture quality? Do I need to pony up for Quicktime Pro? I'm willing to accept having the files being a little bigger. The file size is not much of an issue, I just want them to play on my AppleTV.
