Frames off the end of a clip (was darker images...)

Paul,

It's not actually all-zero off the end of the clip in FCP. It's fully opaque and black. Too bad.

I'm seeing frames of r408 pixels, all of which are (255, 0, 128, 128).

Bug or feature?

I believe that one difference between FCP and Motion is that if you request a non-existent frame (a frame that is before the start of the media or after the end), Motion will clamp to the nearest available frame while FCP will return an all-zero bitmap. Are you averaging multiple frames together? That could produce darker frames if some of the images aren't there.
