One for movies or animations is where they only save what changes between the frames. So if you have 100 frames all black, change them to one black frame and set it so that it takes up the same length of time as the 100 frames did. If you have a shot with blue sky, and it doesn’t change because all the action is going on in the lower half of the frame, save the blue part of the frame and lengthen it/draw it out the same way as was done with the black, once something moves, only then do you have something you need to keep. This can be done for 10000 frames in a row, or it can be done if there are 2 frames with only 10% of the screen the same as the one before it.
