So ... i think i just did about 15 hours of keying and editing and its all for naught.

Pictured below are my elements/scenes. The entire music video was shot on blue screen.

What I did was

1. film
2. import and organize shots in FCPX
3. export each camera angle to AE (still with blue screen intact)
4. key out every camera angle in AE and exported each angle back into FCPX
5. took the Keyed out shots in FCXP and did a Master Edit (with effects and coloring in FCP)
6. Now back in AE and want to add disco lights back ground and stuff to the final edit

But I'm realizing I probably should've added my disco lights backgrounds during keying.

Am I COMPLETELY wrong now?

When I add my Final Edited video in my timeline in AE and throw a disco lights background into AE and select "Screen" or "Add", my footage is too transparent.

Original footage ready to Key


Footage FROM FCP with black background and lighting and coloring added


Example of disco background I'd like to add BEHIND actor



What I'd LIKE it to look like. (I went back to my unedited AE session and threw this BG into my Keying Project)


Do I have to go back and RE-EDIT my footage??

IF i have to go back and start from Step 2 ... Oh man ... its gonna a TON of work.

I don't really have a way to reference which shot is which without just eyeballing which angle/take I used.

If thats the ONLY way to do this right, I'll do it.

If someone could help, that'd be great!

Although I haven't used FCP, I assume it is the same deal as with Premiere: You can replace the clips with new versions, either by some sort of "replace clip"/"reload footage" function or by rendering new versions of the AE footage (now with your background added) with the same file names as the earlier. If you have no use for the current versions you can overwrite them, or if you are unsure, copy or move them somewhere else for backup.

Should be no work lost.
