I think I may have entered the wrong frame numbers for the first two sequences. I was trying to build an avisynth script to replace the frames but it wasn't working with the original frame numbers so I think I may have moved the frames up or back to try and get the script to work. I checked on the video itself and here are the correct frame numbers:
Baby Herman finger scene:
6888-6892
6903-6911
Betty Boop flash:
26226
