CUDA app to capture video games. can be created?

Greetings,

I don’t know anything about programming, But I first thought of this about 6 months ago…
Can’t a games video capturing software be created using CUDA? something like fraps (www.fraps.com).
There are few capturing software applications used a lot by gamers worldwide, but they all suffer from the same thing and that’s being heavy even on latest CPU’s!

a CUDA video capturing software using the GPU parallel power would be a real great idea.
After all it’s nvidia and it would be introduced widely to gamers in no time.

Thank you
