Eli5 why we can’t make cameras with 2 perspectives that alternates between to do 3D video

205 views

This might be a stupid idea, but without a microscope, it seems feasible, imagine having two cameras recording, and on your screen at home we alternate between the cameras every frame to make 3D video, this is almost what’s already happening in our eyes so why not in media?

EDIT: I think I phrased myself poorly, I don’t mean a screen that sends two images or why cameras are this and that, I mean footage that gives one frame from one camera, and the next frame from the second camera, alternating back and forth to make our eyes mens it together into a 3D picture

The problem is not the cameras. 3D movies are filmed using 2 cameras to capture images as though it is viewed through our eyes.

The problem is that when the images are displayed. One image has to go in the right eye and the other into the left eye for our brains to perceive it as 3D. This can be solved in a controlled environment like a cinema but not so easy in other environments unless we wear headsets.

The problem isn’t the recording or even the broadcasting. The problem is the projection or display.
