Researchers from ETH Zurich and Disney Research are presenting a method for optimizing rendering of animation sequences with path tracing. Their method provides significant improvements in denoising, spatial upsampling and temporal interpolation. Watch a video and find out more on Disney Research.

I love this Disney approach to software solution vs hardware solution.
It seems like a “Neat Video” filter inside the most noisy sample based render elements (GI, shadow and reflection) at computatio time for a better quality (like rendered dof vs dof in post porduction).
The key thing hete appears to be the temporal analysis and the channel separation, I wish Corona team could access this white paper and could use it (if it’s for public use)
Cheers!
Brilliant work by Disney. If properly implemented I am sure could be a game changer.
Let’s see if this will be available at all, lots of these great papers get published, but almost never implemented in actual software. And since Disney is not a software company, I doubt they will give these (patents?) away.
But to come one step closes to such a useful solution a denoiser with motion vector for compositing tools like After Effects would be great…
renderman from pixar/disney has integrated this tech since v19 and now more with v20
