Not much probably! Silly question: Let’s say I cut the clip from the 1 minute mark to the 2 minute mark and then change my mind. How do I restore the video that was cut?
One other thing: Using key frames, I can make a bit of an effect so that maybe the image scales down to 0 over just a few frames. Looks a bit more professional I think, especially if another clip does a “lightning” animation as well.
