Ahoy mateys, I’ve sailed the docs and rode the forums but I need some help on how best to rip and encode a 3D BRD. I’ve managed to use ffmpeg to create a kind of SBS video but it’s wrong and there’s a green bar between the feeds. What is the magic sauce I’m missing? Makemkv is what I used to rip.

Anyone have some one-liners or tips in the documentation that don’t suck?

How about this tool? As far as I'm aware plain FFmpeg can't decode MVC (or am I wrong?)

I first rip to MKV via makemkv, I rip it like any other 2d stream. The video file ends up being left/right interleaved.

I then used ffmpeg as documented here https://ffmpeg.org/ffmpeg-filters.html#stereo3d

To separate the left and right channels into sbs file. It ends up with a MKV that is twice as wide as a 2d video steam. I guess maybe my problem is lack of understanding (on my part) of sbs format…

If it's twice as wide as you want, just resize it. More important is that you probably ending up with both planes, left and right being identical, meaning it will not have 3D effect. Just tested it myself with latest version of ffmpeg. Still no official MVC support it seems...
