Ok thanks Stephen. I sent it again, and think my issue has to do with render files from Color.
From my FCP timeline (which shows all the clips as .mxf (960×720), both my pre color corrected files (.mxf), along with the 1280 x 720 Apple ProRes files exported from Color back to FCP (the sequence being used) are being sent to Motion. The tricky thing is the 2 versions give the clips very different names, and formats.
So now I realize that’s my basic problem, I have the DVDPRO HD footage in my Motion project, and the .mov APR files created when I exported from Color back to FCP. I’d like to work with the color corrected, APR (1280×720) files, but they have very different names and don’t show up in either timeline (FCP sequence or Motion’s) so I don’t see how to work with them.
This has to be a real newbie issue, but I’m stuck! Thanks again!
