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

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

We can do that and you used to be able to buy cameras and tvs made to do that. I don’t think there are widely available anymore, as they apparently were don’t a financial success. I have a 3d TV uses polarization to split the two images, but there isn’t a lot of content that takes advantage of it.
