Subject: QT scroll playback shakiness?

I have a scroll running at exactly 119.88 pixels/sec, but playing back =
on the desktop progressive (and ProResHQ). I've noticed that sometimes =
otherwise optimal scrolls like this will alternate from smooth to =
slightly shaky and back to smooth randomly through playback in =
Quicktime. Is this just a quicktime playback thing? Anyone else noticed =
this?

It's usually completely smooth in After Effects itself.a

I've seen it quite often before but just now had a client ask about it.

Thanks,

James
