As others have said you need to cut it first - exactly the same as if you were using the Comp Tool itself.
In addition to the mechanics of comping what techniques do folks use to make the whole task smoother?
For example (but by no means the only issue), when loop recording you can end up with a lot very similar takes that need to be evaluated and ranked (e.g. is A better than B, and how does the winner then compare to C… repeat… repeat…). I end up with paper lists noting which takes I liked. Is there a smarter way that others use?
I recently tried color coding different takes. Not sure that helped me much - but man that was a fancy looking project.
