Video Gurus I need Help

I couldn’t find an appropriate forum to ask this, so I’ll post here. So “wrong forum” comments need not apply. If I have a quicktime movie and that particular quicktime movie has an animation in it that I want is there some type of program available where I can actually cut or crop that animation out while keeping the animation in-tact? (no I’m not trying to steal an animation, it’s my clients need it for his project). It doesn’t sound like it’s possible but hopefully I’m wrong, thanks!
