nested seq stutters
on Aug 14, 2010 at 6:53:12 pm

Im working in 1080i pro res. I have a nested sequence of 3500x3500 sq pixels composed of a grid of photos. Much like one would do in AE, I'm panning, scrolling amd zooming thee nested sequence around within my 1080i seq. But the motion looks jittery. As if it wasn't field rendered. it is all rendered of course. Zooming in looks smooth as glass. Oddly, purely vertical moves are fine. Horizontal are bad. Diagonal are the worst. Any tricks to getting FCP to be a better compositor?

Try the Animation codec. ProRes and odd frame sizes do not play well together for some reason.

Well I'll try anything. But since the 3500x3500 sequence isn't actually being rendered you'd think it wouldn't matter what codec it is. But I've seen FCP do crazier things.

Well, after wasting a couple hours testing, I'm just nuts I guess. Same effect field rendered in 1080i in AE produces same result for diagonal move (sans motion blur). I even went back to 480i in DV just to test the old standards on a progressive PVM tube monitor via a DV deck instead of the Matrox output just incase Matrox was doing something. Their updates have been less than stellar. But still same stuttery result.

I guess it's just too fast a move or I'm getting hyper sensitive to all this stuff. Adding motion blur in FCP improves it but adds a year to render times of course. So I'm not crazy. In relation to this issue at least.

I wasn't nuts! Seems my matrox mini had decided it wasn't going to output full frame rates or fields or something. Today, after a full system crash, power down and restart, everything is smooth as glass. Hardware error!
