When you switch your background to anything other than black, Final Cut enters its legacy "Non-RT" display path. The render settings in this path are quite different. There is some documentation for this in the FxPlug SDK, in a document called "Rendering FxPlug Effects In Final Cut.pdf". Stills are handled differently than video in this path. The mismatched aspect ratios for the input and output seems to be a bug; I'll check it out. Let me know if the document doesn't answer your questions, or if it leaves you with more questions than answers (certainly possible!). 5. Change the canvas window background to one of the other options (i.e., checkerboard). Is there a reason for the change in pixel aspect, and in particular seeing different aspects for the input and output images? I see slightly different behavior for still images. While the pixel aspect changes between a black background and any of the others, the input and output pixel aspects are the same. Why the difference between still images and video?
