I was kind of hoping there was some sort of hidden check-box I could tick that said, “Treat this comp as though it were pre-rendered.”
I’ll give the examples that inspired the question. I did resort to pre-rendering in these cases, but I was wondering if there was another way:
Suppose I had a stop-motion sequence I wanted to composite into some video footage, and I spent a bunch of time masking out the feet for a clean key before realizing I had let it interpret the stop-motion as 30fps when the video is 24fps?
Suppose I had a Super 8 transfer that was pretty shaky, so I stabilized it based on the sprocket hole, only to realize one piece of footage in the middle had been spliced in backwards, so it’s upside-down and time-reversed?
