I hope that I am posting in the right room.
Why is common to find high amount of noise in animated films in scenes with a lot of camera movements. Some graphics and shapes generate a lot of noise in between the blend of the frames. It is an issue related to render, layers, textures, compression, etc? I am very curious about it.
I attach two images with examples. View the images in 100% size to see the noise more in detail.
I appreciate your time to reply.
