How to do that hip hop music video bounce effect?
Hi, how do you do those bounce effects like in the Hype Williams music videos, usually on the kick drum and the image sort of bounces in and out quickly very smoothly? Been messing about with image size and key frames but its quite crude and the effect I want is supposed to be quite fluid. Is it something like in combustion where you can mess about with the curves in between key frames or is it something else?

Do you have a link to an example?

This has loads of it…

The bits where the image bounces like a woofer speaker cone… and some ladies to look at too 🙂

Do you have After Effects?
Check out sound keys. Sound keys creates key frames from audio sources that you can then map to different parameters such as scale, rotation, so on and so forth.
Motion 3 might have some of this sort of functionality built in to it, but I haven’t played with it.

I’m almost certain I saw this demonstrated at NAB, but I haven’t had any use for it so I’m not 100% certain.

I’d just do this in Motion (After Effects, better yet) and animate the scale of the shot. It’s probably best done with good old keyframes. Experiment with the amount of scale increase, the number of times it goes up and down, the speed of the up/down, and the shape of the bezier curves. You have to create the look yourself rather than relying on an actual kickdrum sound to do it, although that could be a starting point. I’m guessing that the scale motion curve will look like a sine wave, but the shape of that wave and how it decays will determine whether it looks to your eye the way the drum sounds to your ear.

This should give you a start to what you want.

Rather than scale I feel pretty certain that the parameter being animate is something like “Bulge.” Not in front of FCP right now to check the name but the center of the image is popping out more than at the sides. And there’s lots of overshoot.

I totally agree with that. The bulging of the center is another trick to make your brain think ‘subwoofer.’

Cool thanks, yea after reading all that I’m thinking of a slight magnify glass effect, using soundkeys on the kick and have a slow exponential curve between key frames on the x/y scale magnify effect (maybe the z?). Either that or maybe I’ll try shooting a tight close up a big speaker cone with a couple of tracker markers. But yes it dose look like its emanating from the center doesn’t it? Just been wondering how to do it, cause someone asked me if i could… and now i just have to know… !

Are you shooting HD, I hope?
