Thanks Jerry. So I guess Compressor can convert all these different files.
Including frame rates and scaling?
Is the best size for FCP 720×486?
Would there be any advantage to doing the scaling + rendering in AfterEffects instead of Compressor (especially if I have the original AE project)? Or would Compressor do the best job?
Still confused why FCP seemed to scale the 640×480 clip all around in the canvas window, while the 720×480 clip was not scaled vertically. In other words, the 2 clips next to each other in the timeline, both 480 pix high, appeared as different pixel heights, even after rendering. Any idea why?
Your help is really appreciated.
