This seems like it should be an easy question, but I can’t figure out an efficient way to do it.
If I have an animation, and I decide I want to slow down some motion in the middle of the animation, what I really want to do is ‘add frames’ at a particular timepoint, so that all IPO keyframes which follow that time are shifted together.
What I’ve found to do so far is individually select each object with an IPO, then select the keyframes which follow the timepoint, and manually offset them. If I have a lot of object with different IPOs, this becomes pretty tiresome. If there was a way to edit multiple IPOs at once so I could boundary select and grab across all of them at once, that would be much more efficient. Or maybe there’s a command for this particular operation I haven’t come across?
(For object which haven’t “appeared” yet in the scene, I realize I can select them and use a time offset, which is pretty close, but doesn’t help if I only want to offset the latter portion of their motion, not the whole thing.)
