Stabilize then unstabilize a clip

I have stabilized a clip, applied different effects to it and now I want to unstabilize the clip again.
Because of miscellaneous reasons, I stabilized the clip with the motion tracker, not the Warp Stabilizer VFX (I've had some serious issues with the Warp Stabilizer VFX lately, however, I've submitted a bug report to Adobe about this).
Anyway, I know that in the new composition containing the pre-comp with the applied effects I'm supposed to pickwhip:

  • Position (in the new comp) to the Anchor Point (in the original comp)
  • Anchor Point (in the new comp) to the Position (in the original comp)
  • Rotation (in the new comp) to the Rotation (in the original comp) and multiply it by -1


But... what about the scale? How do I "reverse" the scaling caused by the motion tracker when the stabilizing process took place?

With what you wrote, I don't think you had to stabilize the clip in the first place.
That aside, if you used AE's point motion stabilizer, Just delete all the keyframes it created.

Trust me Dave, it was absolutely necessary.
The project is more complex than what it looks like from the screenshots.

Well, you still used point stabilization. Just delete the trackers. Done.

I would try

100/pick-whipped-scale

Unfortunately, that didn't work:

Scale is 2 or 3 dimensional array, so you would need to construct that differently.

If 3-dimensional, it would be [100/pick-whipped-scale[0],100/pick-whipped-scale[1], 100/pick-whipped-scale[2]]

If 2-dimensional, drop the third part.

Don't know if it will actually do what you want, but it might.

No, it just made the clip smaller, unfortunately. Hmmm, I thought this wouldn't be THIS hard to figure out. Not a huge problem, though. I will just have to use the Warp Stabilizer VFX, even though that is not a problem-free experience either.

Finally figured it out thanks to Rick Gerard on the Adobe Community website:

x = value[0];
y = value[1];
tx = comp("20180915_203237").layer("20180915_203237.mp4").transform.scale[0];
ty = comp("20180915_203237").layer("20180915_203237.mp4").transform.scale[1];
nx = x/tx*x;
ny = y/ty*y;
[nx, ny];
