Jitter and frame jumping with the replicator

I'm working on my first project in Motion, and slowly, I'm fumbling my way through.

Right now, I'm building an effect where I'm keying a figure off a green screen with Primatte. That footage, I'm feeding into a replicator so he quickly expands out of a central point into a 4x4 grid and I've got 16 miniatures of him in my background.

I've got the effect built, but there's some frames that jump and jitter and I can't figure out why. Is there a problem with scaling things in the replicator? Is there a field interlacing problem? Any suggestions as what to look for?

Thanks -

You've probably hit your graphics card resolution limit. Try setting the group containing the elements to fixed resolution in the Group tab of the Inspector.

Thanks! That solved it!
