Browser

The server serves the web app

Run Muxite next to your library and open its address. Nothing to install on the computer you edit from.

iPhone and iPad

Free on the App Store

The app is a client: type in your server’s address and sign in.

What it does

Everything inside the file, without re-encoding.

Tracks

See what is really in there.

Every video, audio and subtitle track, with codec, language, channels and default and forced flags.

Muxite reads the first audio frame, so it tells DTS from DTS-HD, E-AC-3 from E-AC-3 Atmos, and TrueHD from TrueHD Atmos.

  • InstantRename tracks, set languages and flags.
  • RemuxRemove tracks or attachments in the background.

Subtitles

Fix the timing. Fix the typo.

A visual editor for SRT, ASS/SSA and WebVTT: timestamps, text, and shifting everything at once. A raw text mode when you would rather type.

It works on subtitles inside the MKV and on .srt files next to it. Add new ones from a file, by drag and drop, or from an OpenSubtitles search.

Bitmap subtitles

Turn PGS and VobSub into text.

Blu-ray (PGS) and DVD (VobSub) subtitles are pictures. Muxite shows them one frame at a time next to a text box: type what you see, and save the result as a new SRT track.

Drafts are kept between sessions, so a feature-length film can take a few evenings.

Chapters and tags

Edited in place. No remux.

Chapters and Matroska tags are written without remuxing the file. Apply one chapter template to a whole season, fill the gaps, renumber.

Bulk scripts

One rule per line, across a whole folder.

Write what should change, preview it for free, then queue it. Each changed file gets its own background job; files no rule matches are left alone.

Files

Housekeeping, too.

The chores around the library, from the same place.

  • Move, rename, delete

    Files and folders. Subtitles next to a video move with it.

  • Convert to MKV

    .mp4 and .avi in, .mkv out.

  • Verify

    Check a file’s integrity before you trust it.

Fast on big files

It reads what it needs. Not the whole file.

Muxite reads Matroska itself, without ffmpeg. To pull one subtitle track out of a 19 GB file, it reads about 500 KB.

Run the server

One Docker container.

Point it at your media, name your libraries, and give it a password.

01

Add it to your compose file

Mount the same media folder your Jellyfin or Plex server uses, and list your libraries in LIBRARIES.

services:
  muxite:
    image: git.buttilda.com/muxite/muxite:latest
    volumes:
      - /path/to/media:/media
      - ./auth.toml:/etc/muxite/auth.toml:ro
    environment:
      - LIBRARIES=Movies,TV Shows
      - AUTH_FILE=/etc/muxite/auth.toml
      - MUXITE_JWT_SECRET=change-me
    ports:
      - "3000:3000"

02

Make a password hash

The hash goes in auth.toml.

docker run --rm -it git.buttilda.com/muxite/muxite muxite hash-password

03

Open it

Go to the server in a browser, or type its address into the app.

http://your-server:3000

The full setup, including the format of auth.toml, is in the repository.
