QuickTime Movies
Motion supports QuickTime movies using any file format (codec) installed on your
computer.
Although you can import movies in nearly any codec, avoid using highly compressed
clips in projects. Excessively compressed clips can display undesirable visual artifacts.
Fortunately, QuickTime provides many codecs ideal for moving uncompressed or minimally
compressed video files between applications, including Apple ProRes 4444, Apple ProRes
422 (HQ), Apple ProRes 422, Uncompressed 8- and 10-bit 4:2:2, Pixlet, None, Animation,
Apple M-JPEG A and B, DVCPRO-50, and Apple DV/DVCPRO.
Some codecs support alpha channels, which define areas of transparency in the clip. If a
QuickTime clip has an alpha channel, Motion uses it in your project.
