Disney SIGGRAPH Sampling Based Scene Space Video Processing - ON BLENDER !!!

You do not need multiple cameras if you use a video as input for multi-view stereo.

That can work for certain kinds of footage of a static scene, but obviously not for a scene with moving actors.

which BTW is totally irrelevant for some processes like denoise, or deblur for ex. where no kinekt was used and there are a LOT of moving people.
