Cutting out current sky and adding a diff. one.

I was reading in the Director's book and watched the special features on the "Twilight" movie that just came out on DVD.

There was one particular effect that I was fascinated with. In the Baseball scene near the end, they cut out the clouds that were there and added dark menacing storm clouds with lightning.

On a program like FCP/Avid/Sony, how would something like this be done? On the smaller home scale?

Thanks

Sounds like compositing, which isn't what FCP, Avid nor Sony are made for. Get After Effects or Shake.

An important tool in sky replacement if the footage is moving is motion tracking...not all editors have this function like compositing programs such as AE and Motion. However, there are plugins like Boris FX that will allow you to motion track in programs like FCP and Premiere. I would still suggest using AE or Motion for better control and quality.

Here are a couple of tuts that will show you the concepts involved. You can then attempt to translate these techniques to use in various applications.
