I have just released my first Windows app π₯³
It helps you organize your media library by bringing your file names into the format used by Jellyfin, Kodi, Plex etc. with the help of TheMovieDB and MediaInfo.
It's currently unlisted, so can only accessed via this link. It's free. If you have any feedback or encounter any issues, let me know :)

Movie Renamer organizes your movie collection into the clean, Jellyfin-friendly layout β without ever touching a file you didn't approve. Requires .NET Desktop Runtime. Will prompt to install if not present. Point it at your library, and Movie Renamer recursively scans every video, parses the filename for title, year, and edition hints, then probes the file with MediaInfo for resolution, dynamic range (Dolby Vision, HDR10+, HDR10, HLG), codec, and 3D layout. It searches TMDB for the official movie title, and a live preview shows exactly what each file and folder will be renamed to β before anything changes on disk. * Output format `Movie Title (Year) - Edition Resolution Dynamic-Range Codec 3D 3D-Format.ext` inside `Movie Title (Year)\` Examples: - `Night of the Living Dead (1968) - 4K DV.mkv` - `Metropolis (1927) - Extended 4K HDR x265.mkv` - `Nosferatu (1922) - 1080p x264.mkv` * Features - Recursive folder scan with extension whitelist - Smart filename parsing - MediaInfo probe: resolution, HDR and 3D formats - TheMovieDB search and match selection per file - Multi-language support - Edition Parsing: Director's Cut, Extended, Unrated, IMAX, Theatrical, and more - Support for multiple versions of the same movie - Filter for still-to-be-renamed movies - File name customization in Settings - Option to manually edit the suggested name - Dry-run preview: nothing moves until you hit Apply - Undo log: revert any change with one click - Dark Mode support - Keyboard-only control possible * Built for Jellyfin, works with Plex, Kodi etc. This app lets you easily and quickly convert your file names to conform to the official Jellyfin naming convention. It is also supported by Plex, Kodi and other media software. * Privacy Indexing runs locally on your machine. Only TMDB API calls for movie titles leave your PC.
