TrackSplit

Turn your chaptered video library into a tagged music library, ready for Jellyfin, Lyrion, or any music server that reads standard audio files.

What it does

Point TrackSplit at a video file with chapter markers and it splits the audio into one file per chapter, tags every track, generates album and artist cover art, and lays everything out in an Artist/Album/ folder structure your music server can scan immediately. Lossless sources stay lossless. Repeat runs skip albums that have not changed.

Better together with CrateDigger

TrackSplit works on any chaptered video, but it works best when those videos were prepared by CrateDigger.

CrateDigger identifies festival sets and concert recordings, embeds chapter markers at every track boundary, and writes rich metadata into your MKV files: canonical artist names, festival and venue details, MusicBrainz IDs, and DJ artwork. TrackSplit reads all of that and produces a music library where every artist, album, and collaborator is named and linked correctly.

Without CrateDigger you still get a properly split, tagged album from any chaptered video. With CrateDigger the result is a fully enriched music library that stays in sync with your video library. That is the 1+1=3.

How it fits your workflow

  1. Install and verify: install FFmpeg (required) and optionally MKVToolNix, then confirm everything works with tracksplit --check.
  2. Run on a file or folder: one command handles probing, splitting, tagging, and cover art.
  3. Point your music server at the output: Jellyfin, Lyrion, Plex, or anything that reads standard audio tags will pick it up.
