How does a 3D cinema movie get translated into a 2D movie you can watch at home? Do they show you only one eye perspective or do they film a separate 2D version? Or is it something else?

How does a 3D cinema movie get translated into a 2D movie you can watch at home? Do they show you only one eye perspective or do they film a separate 2D version? Or is it something else?

Answer 1

Sometimes they rework some special effect shots, but usually you’re just seeing the left eye view.

Answer 2

Many movies aren’t really shot in 3D, they’re shot in 2D and post-processed to create a 3D image. So a 2D movie existed before the post-processing.
