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?

I would try
100/pick-whipped-scale

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