In my current film I have 6 nest (and probably more coming) going at the same time. In each of these nests there are about 30 separate clips. It's a very complex stop motion scene and it's looking good. The only problem is when i'm in the "motion" tab and make a certain change, say to change the scale, rotation, center, crop, or anything it literally takes a whole minute to show the change on the canvas. Now this might not seem like a big deal but when I have to make very minute changes 10 or more times to 6 or more nests this gets very annoying. I know the problem only exist on this project, because my other projects are still working fine. What i'm wondering is: Is there any way to make make the images very basic or change it to where it doesn't take up as much memory at least until i'm done editing it?
Thank you in advance!
A fool sees not the same tree that a wise man sees.
Nesting is bad habit in FCP 7. If you want to improve performance, render out each subset of the nest into a reference movie, thus reducing the constant multilayer rendering you're asking the machine to do for you.
You have traded the flexibility to change any edit at any point, at any time, for the huge rendering workload of that many nests and sub-nests. You can keep doing that and live with the results, or, make an irrevocable decision once in a while with a rendered sub-master, then re-import the submasters into a parallel timeline, and re-start your layering from that point.
