As I recall, because of a bug, or maybe on purpose, in Motion (3.0 and greater) ARGB buffers are in-correctly marked with a pixel type of RGBA (kFxPixelFormat_RGBA is really kFxPixelFormat_ARGB). This isn't a problem in Final Cut that I'm aware of. Question: Is it possible to EVER actually get RGBA pixels in either Motion or Final Cut? Is support for RGBA ever necessary? In Motion, all textures are RGBA, and in software all bitmaps are ARGB. I believe the bug you're referring to occurred before Motion 3.0 on input bitmaps. And I think in 3.0 output bitmaps are still marked as being RGBA, but the app assumes they're ARGB anyway. I'd have to run a test to verify that, but that's how I remember it.
