interpret motion keyframes & un-stabilize
I’ve stabilized a shot to make rotoscoping easier. I precomposed & keyframed my masks. Now I want to “undo” the stabilize…
I’m assuming i need to use expressions to interpret anchor point data but I have no experience with expressions.
i need to somehow re-apply motion to the nested/precomposed comp that is based on the stabilize data and/or anchor point keyframes… here’s the layout:stabilized footage in comp A > nest comp A in comp B & animate masks > nest comp B in comp C and (somehow) un-stabilize

I think this from Filip will do what you want, he stabilized to add a 3D element (similar to you roto needs), then wanted his original destabilization back and here’s how:

There’s a way without expressions too, I’ve learned recently:
Make All layers 3D,
go the first frame of your stabilisation (where the layer is still fullscreen)
Add a camera, (all should look exactly the same)
Parent the camera to the stabilized layer: if you look through the camera, you’re piggybacking on the motion of the stabilized layer, so it allways stays in fullframe.Sometimes this is not an option because it forces the layers to be 3D.

works perfect…
thanks!
