Let admins set the countdown display, auto-hide delay, and minimum clip length for Skip and Request buttons on Jellyfin and Emby. Add the three preferences to the synced profile and admin defaults. Keep zero distinct from an unset minimum clip length, and label the controls clearly as Cinema Mode settings.
Add an authenticated Cinema Mode endpoint that returns the advertised movie or series as a TMDB ID and media type. Share the lookup rules with Emby. Prefer trailer metadata and owners, recover attached owners by matching file paths, and use playback context when the media type is missing. Keep filename provider IDs and TVDB mapping available without title searches. Add an optional filename or display-name search fallback, disabled by default. Read item and owner metadata without library visibility filtering so private Cinema Mode videos can be identified. Use Jellyfin's compatible item-query API and return an unresolved result when lookup fails or times out.
Expose the Cinema Mode endpoint using the shared resolver and add the optional filename-search setting to Emby's configuration page. Support Emby's string item IDs, parent and series relationships, and owner recovery through matching attached trailer files. Keep authentication and Emby's item visibility checks.
Check that Jellyfin applies the new admin defaults and preserves user values when a default is unset. Verify that Emby saves and loads the preferences, including zero as no minimum clip length.
Cover trailer metadata, owner recovery, playback context, filename provider IDs, TVDB mapping, and optional title searches with release-year matching. Check private trailer lookup without user-scoped library queries, reject ambiguous or conflicting identities, and guard the compatible item-query API. Verify authentication and the response format expected by Moonfin.
Check that filename IDs retain their movie or series provider type. Verify that matching attached trailers must identify one owner and that the Cinema Mode endpoint requires authentication.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Emby's AwaitSearch ignores the 8-second timeout.
The Jellyfin version uses search.WaitAsync(cancellationToken). The Emby version returns the provider task as-is. If the TMDB provider ignores the token, the Emby request waits as long as the provider takes, and the 8-second limit in CinemaService has no effect. Task.WaitAsync doesn't exist on netstandard2.1, so you need a small polyfill with Task.WhenAny.

New setting keys added:
These match the setting names used by Moonfin.
CinemaFilenameSearchEnabled is a separate Moonbase administrator setting and is not synchronized as a client preference.
Compatibility
Testing
Verified trailer identification using typed and untyped TMDB metadata, attached owners, matching file paths, embedded TMDB/TVDB filename IDs, and title-based fallback.
Confirmed that embedded filename IDs work with optional filename/title search disabled. The companion Moonfin PR contains the full testing details.
