What does it mean for Motion 3 to return YES for [_hostCapabilities formatsFloatRGBABitmapsAsARGB]? That makes no sense to me. I thought this was supposed to return NO for hosts that labeled their float bitmaps correctly, which Motion 3 apparently does. This section from the SDK overview is ambiguous, since it doesn't say how Motion corrected this problem: Float Images pixelFormat Correction Motion 2.1 ordered pixel components RGBA in floating-point images, but the -pixelFormat method returned ARGB. Motion 3 corrects this problem. You can determine whether floating-point images are mislabeled by querying [FxHostCapabilities formatsFloatRGBABitmapsAsARGB]. I assume that Motion 3 corrected this problem by changing the component order to ARGB, since that's what I'm seeing in the FxBitmaps, but I don't see any mislabeling. As in my previous message, it seems very odd to me that Motion would switch from RGBA to ARGB float pixels, especially since Quartz doesn't support float ARGB.
