Mocha Pro Fusion plugin needs to be able to access frames before 0

I’ve got a complicated composite that was built but the plate photography needed to be extended at the head after the fact. After trying a bunch of different things, the easiest and cleanest way was to add negative frames to the start of the Fusion comp so that nothing broke with the animation.

The problem though is that now when I’m applying Mocha to do some additional work it’s only feeding in frames from 0 and I can’t seem to be able to get it to access the other frames of the comp.

Being able to access frames before zero in terms of Fusion is a big must I feel.

That is a very interesting problem to solve, I am going to tag @martinb in here and see if it’s possible that there is a workaround.
