There are mulitple ways to identify a video as 3D.
A video can be identified as 3D using the the metadata manager. Simply edit a video:
Then select the 3D format:
In order to properly detect 3D, two tags need to be present in the filename. First, a '3D' tag has to be present. Second, one of the following must also be present, hsbs, fsbs, sbs, htab, ftab, or mvc.
Tags need be be surrounded be either a space ( ), hyphen -, dot . or underscore _. Tags are case-insensitive, so both 3d and 3D will work.
Examples:
- moviename (year).3d.hsbs.mkv
- moviename 3d sbs.mkv
- moviename.3D-HTAB.mkv
- moviename-3D.sbs-720p.mkv
- moviename-3D.mvc.mkv
Older file naming conventions are still accepted by placing one of the following tags within the filename:
- [fsbs]
- [ftab]
- [hsbs]
- [htab]
- [3d] - Indicates half side by side
- [sbs3d] - Indicates half side by side
For example:
/Movies
/300
300 [hsbs].mkv
/Home Alone (1990)
Home Alone [fsbs].mkv
3D can even be combined with the multi-version video support discussed in the Movie Naming article.
Here's an example of a movie containing multiple versions in a single movie folder, some 3D and others 2D:
/Movies
/300
/300 - 1080p.mkv
/300 - 720p.mp4
/300 - 3d-hsbs.mp4
/300 - 3d.hsbs.mp4
/300 - 3d.mvc.mp4
