+### TMDB
+
+TMDB (The Movie Database) supplies posters, synopses, and show grouping for live-action dramas and movies in the stats [Library](/immersion-tracking#library). AniList only covers anime, so TMDB is what gives live-action titles a cover and a description.
+
+Release builds ship with a project TMDB key, so nothing needs to be configured. Set your own key to use your own quota, or when running SubMiner from source, where no key is bundled. Create one for free under **Settings > API** on [themoviedb.org](https://www.themoviedb.org/settings/api); either the short API key or the long "API Read Access Token" works.

+
+Successful `apiKeyCommand` output is cached for the running client until `tmdb.apiKey` or `tmdb.apiKeyCommand` changes. Failed or empty command output uses the bundled key when available and waits 30 seconds before the next request can retry the command. Changing either credential setting resets this cooldown.

+Changes apply to the next TMDB request without a restart.

 When older stats already grouped multiple seasons under one series entry, SubMiner moves parsed episodes into the season-specific entries on startup and rebuilds the affected summaries.
 
+**Live-action dramas and movies.** Anime covers come from AniList, which has no live-action titles. A title that AniList cannot match is looked up on [TMDB](/configuration#tmdb) instead (release builds bundle a key; source builds need your own): only a Japanese-language, non-animated result whose known titles match the parsed filename exactly is accepted, and it supplies the poster, synopsis, English and Japanese titles, and episode count. If nothing matches automatically, open the title and use **Link to TMDB** to search and pick it by hand. A TMDB show spans all of its seasons, so entries that resolve to the same TMDB title are merged into one card regardless of the season folder they came from, and the merged season titles are remembered so later episodes land on the same card. The **All Titles** filter above the grid narrows the Library to anime or live action, and a title's detail view shows whether it is a drama or a movie. Linking a title to AniList again turns it back into an anime entry. Changing providers downloads the replacement cover before saving the new link; a failed download leaves the previous link and artwork intact. A title without a cover clears the previous artwork. Automatic TMDB matching leaves existing AniList links unchanged.
+
 Jellyfin stream URLs are normalized to stable item links before stats titles are shown, so playback query parameters are not displayed in the dashboard.
 
 When YouTube channel metadata is available, the Library tab groups videos by creator/channel and treats each tracked video as an episode-like entry inside that channel section.
 
 A library entry is identified by its parsed title plus any detected season, so the same show can end up on several cards when releases disagree about the title or omit the season tag. Two fixes are available:
 
-- **Merge duplicates.** Hit **Select** above the grid, tick the cards that are the same show, and choose **Merge Selected**. Pick which entry to keep in the dialog; every episode moves onto it and the other cards are removed. Nothing is deleted, so sessions, mined cards and watch time all carry over. SubMiner remembers the merged title variants, so future episodes parsed with one of those names join the kept entry instead of recreating a duplicate card.
+- **Merge duplicates.** Hit **Select** above the grid, tick the cards that are the same show, and choose **Merge Selected**. Pick which entry to keep in the dialog; every episode moves onto it and the other cards are removed. Nothing is deleted, so sessions, mined cards and watch time all carry over. AniList-linked and TMDB-linked entries cannot be merged together. SubMiner remembers the merged title variants, so future episodes parsed with one of those names join the kept entry instead of recreating a duplicate card.
 - **Move a single episode.** Hover an episode row in a title's episode list and use the **→** button to reassign it to another library entry. The correction is remembered, so later filename parsing or Jellyfin metadata cannot move that episode back. For local files, later episodes in the same directory inherit the correction when their detected seasons are compatible and every manual correction there points to the same entry; a file that parses to a title which already has its own library entry keeps that identity instead. Conflicting seasons or manual destinations are left for review. If the move empties the old entry, that card is removed and you are returned to the grid.
 
 Once cover art resolves a series to an AniList entry, cards with compatible seasons are folded together automatically only when the searched title exactly matches an AniList title or synonym. A fuzzy result that points at an AniList entry already used by another card appears as a **Possible duplicate** review above the Library grid instead. Choose **Review merge** to compare the cards and pick which one to keep, or **Not duplicates** to dismiss that suggestion permanently. Entries with conflicting explicit season numbers are left alone rather than merged or suggested.
