Are you roundtripping the motn project?
Sometimes, but not all the time…
Are your Motion/FCP project settings the same (resolution/frame rate)?
Yes, but sometimes I bring in 720/30p and scale it to the SD project.
It happens with stills as well though.
Are you using cohesive versions FCP 6, Motion 3? Done all your Pro App updates?
Yes
Try creating a slug in FCP, same time duration as your current motn clip, send to motn project, copy your layers from the original motn project into the new “roundtripped” project, save, and see if that works…
I’d just re-boot to try and get it back before I’d do this, it really doesn’t solve anything.
If it still gives you issues, consider exporting Animation + Lossless from Motion and import into FCP
But, this defeats the purpose and doesn’t help fix the problem.
Have a good one,
