Re: [Avid-L2] 29.97P conversion to 24/23.976

This is rough no matter how you slice it. Any way you look at it, you're
throwing away temporal resolution in a non-friendly-mathematical way.

Here's what I would say: it's not going to look great no matter what. That
said, I'd find out who did the animation and hope that they can re-render
it out at 23.976p.

Film mode is trying to do a strict pulldown removal - since there's no
pulldown, it's just a brute force drop of field information. Auto is doing
temporal reduction like optical flow as you described. It's never perfect.

I wonder if there's a way to get it to a common point multiplier, like
119.88 fps. (29.97 x 4 = 119.88 and 23.976 x 5 = 119.88). Go up first, add
in as many fake frames as it needs, then divide evenly to get back down.
Maybe somebody out there is working on something like this...
