Composites and Rotoscopes

I'm the one responsible for most of the rotoscoping.
My first complaint is working in 4K. It's like just as we get computers fast enough to do fancy stuff in HD we have to quadruple the processing needs. Sheesh.
For some reason I decided to do this one shot as a 950-frame shot.
After Effects does some fairly decent auto-rotoscoping these days. But sometimes it does something weird like when it took away Kate's face.

But doing a tiny bit of manual roto to get things back to normal is worth the effort.

I'm adding a lot of dust to shots. The dust is impossible to see in stills.
