[jtk77]

Hi follks..its me Jamie again..here is an issue that AE has gotten down perfectly. A/B ing a frame. Is there a way to take a snapshot of a frame..and its loaded in the ram and you make tones of changes with on diffrent operators and then toggle back and fourth from that version to the one thats loaded in the ram?

Yes you can......

Create a dual viewport screen. Load the composite into both viewports. With one viewport selected, select the render to RAM feature....

Once the RAM has loaded into the one viewport, the alternative viewport can be worked on without affect the RAM Cached view....

So you can do a comparision between the 2...
