Anybody know of any work done to improve greenscreen keying? The current old school techniques work quite poorly and require so much manual work. I would imagine with the new work coming out with neural nets etc. there would be possibilities for improvement. This is very cool work and good for certain applications, but seems to produce similar problems like greenscreen to some edges.

Nvidia have had automatic "greenscreen keying" without a greenscreen in some sort of beta for a long time, but it still hasn't moved beyond that: https://blogs.nvidia.com/blog/2019/09/26/nvidia-rtx-broadcas....

Modern green screen plugins/filters are miles better than what they used to be to the point that if the keying is hard, then the image must not have been produced well. By that, I mean an evenly list background (no light fall off producing gradients). Proper lighting of the subject. Proper distance from the background (helps reduce the edges and color tinting).

I work quite a bit with green screen keying. I see the same keylights, ultimattes and primattes used still even in big productions I have worked. Fixing the key can take weeks. Maybe industry is bit conservative and I haven't seen cool new stuff bubbling under, but would love to have new tools in the toolset to approach difficult shots.
