Download Settings
Where the fake-movie/trailer folders are created. Add this as a Jellyfin Movies library and scan it so a Cinema Mode / trailer pre-roll plugin can use the trailers.
Maximum number of trailers to download each time the task runs. Default: 20.
How many pages to fetch from each TMDB source (20 movies per page). Default: 3.
Trailers for movies you already own won't be downloaded.
If a folder already exists for a movie, don't re-download it.

Trailer Rotation

Keep your trailer library fresh by automatically removing the oldest entries each time the download task runs.

Maximum number of trailer folders to keep on disk at once. When this limit is exceeded, the oldest are deleted first to make room for new downloads. Set to 0 for unlimited. Default: 50.

Cinema Mode Integration

When enabled, this plugin registers as an IIntroProvider and injects downloaded trailers before movies — compatible with Jellyfin's built-in cinema mode support and clients like Wholphin. The output folder must be added as a Jellyfin Movies library and scanned before trailers appear.

Number of trailers to play before each movie. Set to 0 to disable. Default: 1.

Advanced
Full path to yt-dlp. Required for 1080p quality. Also needs ffmpeg on the system PATH. Leave blank to use the built-in downloader (720p max, zero extra tools).
