Hey, thanks for the reply. That’s a good solution late in a project, but I’m hoping to avoid doing that for every little timing tweak.
This same issue comes up if I want to add 10 frames in the middle of a complex composition. First moving trimmed layers forward, then moving keyframes forward. Then making sure I didn’t mess anything up. In that case too, I could pre-compose, split, time-remap the first segment and add the frames I wanted. I was hoping there was just a secret hidden “add frames here” button.
I suppose I could avoid this by just never trimming layers (and toggling visiblity with keyframes, time-remapping to control when things should play), but it’s so much less confusing to look at with trimmed layers.
