Thanks, works great for me, except I always get a blank frame (from the overlaid composition) at the very end of the first loop (or maybe its the first frame of the second loop). Interestingly the blank frame does not reappear for the rest of the project (with dozens of loops). Please note that the whole project doesn’t blank out on that frame, just the composition on the top layer, and just for that one frame of the whole project. Any ideas?
