Next Steps & What to Expect

Initial Sync and Downloads

Once your connections are set up:

  1. Initial Sync: Trailarr will begin to sync media items from all your configured and enabled connections. This process involves fetching lists of your movies and series.
  2. Trailer Scan: It will then scan your existing library (based on your path mappings) to see which trailers you already have.
  3. Magic Happens (Downloads): Trailarr includes a scheduled task, "Download Missing Trailers," which typically runs every hour by default (this can often be configured in Settings > Tasks). This task will identify media items missing trailers (according to your profiles) and attempt to download them.

How does Trailarr work

  • Trailarr gets all the Movies and Series from the Radarr and Sonarr connections
  • Scans the media folders to find any existing trailers. Trailarr detects a file as a trailer if it meets these conditions:
    • File should be one of (avi, mkv, mp4, webm).
    • It should have the word trailer in it, episode files (with SXXEXX) are ignored even if they have the word trailer in them.
    • It should either be in the media folder itself, OR in a subfolder named trailer/trailers (not case-sensitive!).
  • Runs some tasks every 60 minutes (configurable in Settings) to refresh the media from Arrs, and Download Missing Trailers based on Profiles.

A Note on Patience

Please be patient, especially during the first sync and the initial "Download Missing Trailers" task. The time these operations take can vary significantly depending on:

  • The size of your media library: More items mean more API calls and more data to process.

  • The number of missing trailers: If you have a large library with few trailers, the first download run might be extensive.

    Do NOT use 'cookies' for large downloads

    If you have added a cookies file in Settings > General during Setup, remove them until the initial downloads are completed!

    Some trailers might fail to download because they are Age-Restricted, don't worry, you can download them later!

    You can set them once those initial downloads are complete!

  • Your internet connection speed.

  • Rate limits of trailer sources.

You can monitor Trailarr's activity through its logs and/or see the status of tasks in Settings > Tasks.

Enjoy your automatically managed trailer collection with Trailarr! 🥳🎉
