Had a similar problem... bringing in computer screenshots captured as moving video (via Ambrosia's Snapz Pro X). Snapz saved the files out in the Animation codec with odd frame rates (11 fps) in my case. Each time I brought them into Motion (in a 720x480 SD project), they looked great but the length of the Quicktime movie file was usually half of what it should have been. (Snapz was also automatically adding an unnecessary alpha channel to the files when it saved as Animation, which was causing some problems with playback).
I fiddled with a variety of the Quicktime compression types and the only one I found that would retain close to the quality level of the original file was by using PhotoJPEG. The downside is that it takes about a 40 mb Animation file and inflates it to about five times as big-- in this case, up to 212mg! I also tried DV in hopes to keep the file sizes down but clarity of the image degrades considerably.
Here are the Quicktime movie export specs I used.
Compression type: PhotoJPEG
Frame rate: 29.97
Keyframes: All (Default)
Compressor Depth: Color
Compressor Quality: High
Dimensions: 720x480
If someone has a better way where I can retain the large size of the original frame grab, please share it....
Thanks!
