Do you need ALL your clips in AE?
You can export a ref file to the desktop.
Import that into AE.
Do you work and render out same codec/size/frame rate.
OR
Export just the clip(s) you want to work on in AE.
Drop the clip into a new sequence by itself.
File export “current settings” ref file is fine.
Import into AE, do you work/effects.
Render out matching the same clip specs.
import into FCP, copy replace content on the old clip in the edited piece.
Make sense?
