Swapping left view in MVC file with 4K?
Posted: Sat Mar 30, 2024 1:37 am
Hey all, apologies if this is a newbie question that is easily shut down.
I rip a lot of 3D Blu-Rays using MakeMKV and BD3D2MK3D so I can watch them in a VR headset. I also occasionally rip 4K UHD 2D discs.
It's my understanding that the MVC format stores the full image for the left view, and then stores the right view in a compressed format that essentially just describes the way in which the right view differs from the left view.
Would it be possible to take a 1080p MVC file and swap out the left view AVC stream with a 4K version of the same movie? (Assuming the left view in the 3D version perfectly aligns with the 2D version of the movie). The left view would be fully "upscaled" to 4K, and the right view would be mostly upscaled. Obviously it wouldn't be perfect. Any sharp edges between 3D layers wouldn't be as crisp, and of course the extra visual information revealed by parallax shifts would still be 1080p. But, for the most part, the image quality would be greatly increased.
Since no one has done this before (as far as I can tell), I'm assuming I'm misunderstanding something big. But is there really any reason why this wouldn't be possible? Does anyone know of any software/tools that could be used to attempt this?
Thanks!
