Trying to bring 720×540 square pixel QT into 720×486 nonsquare sequence?
I am trying to bring a 720×540 square pixel uncompressed “none” Quicktime into a 720×486 nonsquare pixel sequence but I can’t see any video even when I render the clip.
What should I do? (besides re-render it out in After Effects)Thanks in advance!

Not sure why you’re not seeing it (probably an alpha channel issue) but you should render it at 720×486 in AE. Why would you render it at 720×540? I realize that is square, but AE takes care of mixing all the square and non-square issues. You should always work in AE at the native format you’re creating for for best results. If you must work in 720×540 (still don’t know why) then your last step should be to place that comp into a 720×486 comp before rendering. Avoids field mush if you’re using fields. If you’re not using fields, wouldn’t you want AE to do the scaling instead of FCP? FCP isn’t exactly known for scaling and subpixel rendering quality. Ugly.

A high-end Hollywood post house gave me a 720×540 square pixel uncompressed QT when I asked for 720×486. I’m not sure why they gave me that either, or why it won’t render into my 720×486 sequence. It plays fine with the QT Player App.

Yes. It was an alpha channel issue. I turned it off.

Yeah, they rendered an inverted alpha I bet. But I would probably have used AE to render it to your seq codec. It does a better job scaling, and it would only need the one render step. It would only take AE a few seconds to do it.
