I have an MK3D video file containing a 3D movie. But my video player (Skybox for Oculus Quest) does not support MK3D files, only MKV files. My question is, how do I convert my MK3D file into an MKV file, while keeping it as a 3D video?
Both MKV and MK3D are part of the Matroska file format, so I tried simply renaming the file from “.mk3d” to “.mkv”. But that makes it play as a 2D movie, it loses the 3D aspect. So how do I preserve the 3D nature of the file?
.mkv
files in 3D mode, as the file-extension difference is just a convenience feature to put the player into the right mode. If Skybox doesn't support that, there is a list of supporting players in this article, to which you should add VLC.
