Help when you need it

Use another device to sign in

Quick Connect lets an already signed-in phone or computer approve the device you’re setting up. Use it when your app shows a Quick Connect code.

  1. Keep the code visible on the new device.
  2. On a phone or computer, open Blackbeard’s Vault Jellyfin and sign in to the same Jellyfin account. If typing the address, keep the s in https://. Usernames are case-sensitive; match the capital and lowercase letters exactly.
  3. Open your user/profile menu, choose Quick Connect, enter the new device’s code, and confirm.

If Quick Connect is unavailable, use password sign-in on the new device. A local app PIN is a different optional setting.

Something not working?
  • Can’t connect? Check the s in https:// and copy the full server address again. Don’t add a port number.
  • Can’t sign in? Match every capital and lowercase letter in your username. Use your Jellyfin account, not your email or an Emby login. Remove accidental spaces.
  • Video or sound problem? Close and reopenUpdate the app, checkreopen for an update,it, and try another title. The Moonfin alternative is another option.

Picture and HDR settings

Keep the default player settings for your first movie. Browser and desktop playback support differ. On Windows, Moonfin normally converts HDR for SDR output.

Windows / Linux: Jellyfin MPV Shim is another option for users who want more playback control. Its full library interface is newer than its playback engine. Official downloads and instructions.

Some native apps handle audio, subtitles, or video formats better than a browser. If the browser struggles with a title, try Moonfin or ask Cruv.

Why this app? Details and sources

The browser is the easiest free starting point across computers. Current desktop clients are in transition: Jellyfin Desktop 2 is a prerelease, and MPV Shim’s full browsing interface is new. A long-lived playback engine does not establish a new interface’s reliability.
