I have a bunch of animated clips dynamically linked from After Effects that have suddenly locked in position. I can move normal video clips around, between tracks and back and forth. The AE clips move if I do a Ripple Delete, and I can trim the beginnings and ends of the clips, I just can't move them around. I also can't drag new AE clips into the timeline.
I'm hoping this is something stupid I overlooked and not a serious problem.... any other you need to help diagnose? Thanks!!
