Extras

Extras can be added to movies, show series, show seasons, and music videos in a few different ways, as listed below.

Extras Folders

One of the cleanest ways of adding extras is to place them in subfolders within your media folders.

Supported folder types are:

• behind the scenes
• deleted scenes
• interviews
• scenes
• samples
• shorts
• featurettes
• clips
• other - Generic catch all for extras of an unknown type.
• extras - Generic catch all for extras of an unknown type.
• trailers

File Name

Some types of extras support a special option if you only have a single of that type. These options are to name the filename a specific word when stored in the same folder.

Supported filenames are:

• trailer
• sample
• theme - Audio file of the theme song

└── sample.mp4

File Suffix

If you would rather keep everything in a single folder, you can append special suffixes to the filename which Jellyfin picks up and uses to identify the file as an extra. Note that, with a few noted exceptions, these suffixes DO NOT contain any spaces.

• -trailer
• .trailer
• _trailer
• trailer - This is a space followed by the word trailer
• -sample
• .sample
• _sample
• sample - This is a space followed by the word sample
• -scene
• -clip
• -interview
• -behindthescenes
• -deleted
• -deletedscene
• -featurette
• -short
• -other
• -extra
