Hopefully someone can help!

So, with some free time on my hands, I want to do a short quake 4 movie, but that's as much as I'm saying right now.

Anyway, I see a number of programs that people use, and someone told me that most people don't use Fraps to record Quake 4.

I was informed that there was a 'config' that just records tons of screenshots, then you compile them in a video program.

Is this true?

I just need some guidance on this. What programs to record, compression, etc. I know which ones to use (I think), but I want to make sure it still compresses properly, and looks great, etc etc.

Any help would be awesome =D
