There is in fact a Ripple and Overlay options in AE. Though not extremely useful. If you open a Layer window (the layer’s window where you could motion track or paint the footage) look at the bottom of the Layer window frame. You have an in time marker button, in timecode, an out time marker button, out timecode, duration of the selected clip, and drum roll please……. Ripple Insert Edit Button and Overlay Edit Button. These are NOT new. They have been available as long as I’ve been using AE. And I can’t think of a single time I’ve used them. They are clunky and involved. But just read this and thought I’d clear the matter up.
