    Ok someone explained to me what Shake was today. They basically said it was for complex scenes with alot of different things going on but all shot at different times. Is that correct?

    And if that's true then why wouldnt one just use the blue or green screen for a shot like that? Does shake look more real? I'm new to this and really dont quite understand.

    It takes the basics behind blue/green screening and BAM! kicks it up a notch. Check out the Shake info and the tours on the Apple site to get a better grasp of everything it does.

    Shake is a compositing tool so, for example, after you shoot your actors on a green screen, shoot the cave you want to put your actors in, and create the 3D creature you want your actors to fight you combine those elements using Shake so it looks like your actors are in a cave fighting an ugly cave creature.

    jayeskreezy,

    it's really a two-step process. The green or blue screen is used to shoot the source footage, such that you can isolate ("key out") the subject you record in front of the green/blue screen. Everything but your subject is then transparent. This is step 1.

    Step 2 is to use multiple sources of footage, maybe combined with still images, and stack them on top of each other such that it looks like a single picture. Final Cut can do this in a very basic way, but Shake just offers so much more flexibility to help you make it look real. Shake can also help you with the keying mentioned under step 1.
