I re-render clips created in AE that already exist in FCP all the time, on just about every project. Here's my method:
- Delete NOTHING concerning the bad AE clip in FCP, then quit FCP.
- Using the Finder, trash the bad AE clip.
- Open AE, correct the comp if necessary, save the AE project (very important!) then render using the precise same file name as before AND to the precise same folder as before.
- When the render is done, DO NOT SAVE THE AE PROJECT! You already saved it prior to rendering, remember? Just quit AE without saving.
- Open the FCP project. Your AE clip should already be there, ready to go.
If this doesn't work, you have other FCP issues going on.
I occasionally have those Homer Simpson "Doh!" moments when I look at the newly-rendered AE clip; it's easy to overlook a small error. By saving before I render, I simply have to repeat the process described above.
