HV20, GreenScreen, and 24P

Folks don't get the obsession over 24P.
Here's why: visual effects.
60i video has 30 frames per second. 24P has 24.
Six more frames per second to render out.

It's easy to reverse telecine to go from 60i to 24P with the HV20 (don't buy the hype of 24frame. It'll do, but true 24P is best).
It's a clustermuck to try to take 60i to 24P from any other camera (one that doesn't have a 24P mode, mind you.) Takes a lot of renders, and you're dropping 6 frames per second, and it's just a mess and looks super choppy. Don't bother.

NOW:I can always telecine the 24P after applying effects and color correction to get it to 60i.
DVD players automatically play back 24P files to 60i for 1080i TV sets.

But back to the 24P. After Effects renders frames. THe less frames, the faster you go.
I like less frames.
Shoot with HV20. Strip
