Remove Markers and Add Scar

Script

The first thing to do is to denoise the plate so that it is easier to track the markers.

Removing Markers

And then I tracked the markers on his face in Mocha Pro. I actually tried to track in Nuke, but it cannot be tracked very well, I think it’s because the markers are too small to track. It tracked much better in Nuke, and then I exported into Nuke.

I ctrl drag the set key icon next to the translate, rotate, scale, and center tabs of the Tracker node to the exact same tabs of Roto node. Then the roto can follow the movement of the tracking information.

I used the Inpaint node to remove the markers with one click, it automatically removed and blended the spots I masked out . After removing the markers, there is no noise in the spots. The next step is to add and match the noise back.

I used ReGrain node to add the noised back to the spots. Then, add alpha from the masked out spots and premultiply it to merge the grained spots with the original plate together.

Lastly, I added the same scar from Harry Potter on his face. I reformat first and masked the scar out. Since his forehead is not flat, I used Rotopaint to smear the scar along the higher part above his eyebrow. I used Framehold node to keep it from the beginning to the end. And then, I color corrected to match the color on his skin. Lastly, I merged the scar over the plate.
