The following short before/after clip shows some new tricks I've developed for film restoration. These same tricks apply to video.
This 8mm film was taken in 1954, and the camera (not the projector) malfunctioned and didn't bring the film to rest before opening the shutter. As a result, not only were the frames jumping up and down, but many of those which jumped were blurred. I went through by hand (thousands of frames) and marked each jump frame. I then developed software which deleted the jump frame and then used motion estimation software (similar to Twixtor which is used for synthesizing slow motion) to create a brand new synthesized frame which I then inserted in place of the damaged frame. So, on the right-side "after" version of the clip, about 50% of those frames are computer-generated.
I have used this same technique -- although thankfully on a much smaller number of frames -- to remove frames where a photographer's flash ruined the frame, or where there was a dropout or, on older analog video, where there was a glitch or dropout.
