Motion does weird things on export - HELP PLEASE!

Hi guys,

I'm having trouble with Motion. I just build a backdrop to use with some green screen stuff we shot. I used a layered photoshop file and animated some of the layers. All animation is done using the "oscillate" behaviour. The several oscillations are linked to opacity, position, rotation and scale.

Everything plays perfectly in the motion timeline. BUT as soon as I export either a mov or a generator, things go terribly bananas. Items that should just "breathe" a little suddenly rotate like mad. Opacity does not smoothly fade in and out but just jumps on/off.

Any idea what the problem could be?

I'll try to attach a screenshot, not sure if it works out, I've had my problems with it before.

Thanks for your help!

Yeah well, no screenshot then. Any advice on how to do that? Attach file won't work for me.

If I could get a copy of the Motion project, I'd look it over for you.
