I've got a fairly large project, 20 layers of gfx etc that is killing me every time I render a 10 frame dissolve! 4 seconds to render, 30 seconds to save after every change. I have my autosave set to 15 minutes, but the saving after each render is crazy. Maybe I just don't notice it on small work? The attic edit file of the project is about 220,000kb in size. Any way to lessen the amount of times it saves?
