How to prepare final effects with 'rough' take footage?
Hi... I am working on a well timed continuous two camera shot of footage that my 'rough' take has the percise timing, etc, and I want to work out my various effects on the footage in premiere (e.g., keyframes on motion, opacity, etc..)... then, when I finally get around to getting a good take (may be days/weeks from now), I want to basically just swap out the old footage and in the new footage. How might I accomplish that? As far as I know so far, the effects I'm applying are clip itself, and thus, if I replace it, the effects/keyframes will be lost.
I can't (as far as I know) just swap out the media file, as the pre-roll time may be different.. thus the exact frame where effect keys are will be offset one way or the other in that case.. e.g., my rough take may have 95 seconds of pre-roll, whereas my final may be 215, or 17, or whatever.
Tia!
