This docker container can convert frame-packed (mvc) mkv files to side-by-side (sbs) mkv files. All audio and subtitle tracks are copied to the output file.
Makemkv should output two streams one for the left and one for the right eye. This script will take the multi view encoded streams and combine them back into a sbs video.
