Oh man, you are a genius!! I never thought it could be fixed so badass. I think it's the nearest thing of magic Im going to find in this forum
Besides not understanding a thing of the RPN, mt_lutspa is one of those masktools functions I never got to grasp.
Ill get my hands on tomorrow, I already have the scripts blocked for the 2 sources in regards of denoising, etc, the only difficulties I was having was the blending artifact in the first source, and the field-blending in the second.
So for changing parity in the first one, I would need to work on trims, right?
As for the second I will have a closer look tomorrow to play and see what I can do.
These are pretty rare animations so thanks a lot.
