Sync Motion to Audio?

[pianoman1976]

Hello,

I was wondering if iMovie has the ability to alter the speed of a clip dynamically as to sync visual voice movements to a separate audio track?

I want to take silent footage of my parrot talking and sync her beak movements to an audio track of a rap song so that she appears to be rapping.

Is there a name for this process? How is it done? I assume it takes a lot of manual adjustments of some sort. Can iMovie do this?

Thanks.

Man that's a challenge.

Pro's spend days for a few sec. of usable vid.
