Any Way To Split 3d Blu-Ray Into Two Files?

Author

I am trying to make an edit of the IMAX version of guardians of the galaxy and GOTG Vol.2 and I know that the IMAX scenes are on the 3d blu ray. I want to know if i can separate the 3d blu ray into two 2d files (One for right eye, one for left eye) with ZERO loss of quality. Since both films on 3d blu ray have alterations to the 2.39:1 scenes (such as items popping out of the frame) I plan to combine the 3D IMAX scenes with the 2D 2.39:1 scenes on the regular blu ray and author it to blu ray with no loss of quality. How should I go about this project? (Also, when I am done, I plan to do the same thing with Civil War and Doctor Strange).
Thanks

I’m not sure if you can do mathematically zero loss of quality, as I believe 3D Blu-rays are encoded with MVC video codec, while 2D Blu-rays use AVC video codec.

Ok, so how would I do it with minimal loss of quality?

I’ve never done it, but when I did a bit of googling, I think you want to build an AVISYNTH script with this:

MVCSource appears to allow you to decode either stream, at which point you can either write out to an AVI File, or encode with x264 etc.

Got it, thank you!

Did you have much success with this? I’m a bit obsessed with getting the IMAX versions of these movies as they’re MUCH better, and I don’t have a 3D TV. I’m also worried that they’ll release Infinity War this same way, and a movie that was shot 100% in IMAX will be wasted.

Yeah, I unfortunately don’t have enough hard drive space to complete this project. I need to buy a new hard drive to get this done.

I did some googling and I read something saying MVC is backward compatible (it would play 2d on a non 3d player).

The link to doom9 plugin it sounds like one stream (stream 0) is AVC encoded and the other is MVC (stream 1).

If that is true maybe you can demux the avc encoded stream and go from there
