Sometimes when adding keyframes, the time thumb will jump to a different point in the timeline and sometimes add a keyframe and sometimes not. Sometimes it jumps to the head of the sequence then need to navigate back to position I was working on. Sometimes it just jumps ahead or behind 2 second or so and have to pull the keyframe back into place. Skimming is off. Currently working on a Motion title with many keyframes and FCPX is jumping all over the place.
About to jump over to AE. would rather not however.
