So I have this scene where a bunch of balls bounce up and down to the beat of the music. I made a clip of 1 ball bouncing up and down. I want to take that clip and apply it to all the balls in the scene and have them bounce up and down for as long as the scene lasts. How do I do this? Maybe clips aren't the best way, but I would think so. Also, I would like the bouncing to happen slightly randomly. Any ideas?

Thanks.
