OpenSubtitlesDownload.py is a small software written in Python, built to help you quickly find and download subtitles for your favorite videos. It can be used as a nautilus script, or as a regular application working under GNOME or KDE desktop environments. You can also use it in full CLI mode (Command Line Interface) on your NAS, Raspberry Pi or anywhere you want really, as long as you have a working Python interpreter.

The subtitles search is done by precisly identifying your video files by computing unique movie hash sums. This way, you have more chance to find the exact subtitles for your videos, avoiding synchronization problems between the subtitles and the soundtrack. But what if that doesn't work? Well, a search with the filename will be performed, but be aware: results are a bit more... unpredictable (don't worry, you will be warned! and you can even disable this feature if you want).

The subtitles search and download service is powered by opensubtitles.org. Big thanks to their hard work on this amazing project! Be sure to give them your support if you appreciate the service provided, they sure need donations for handling the ever growing hosting costs!

• Use a GNOME/GTK or KDE/Qt GUI depending on your favorite desktop environment
• Or just use the CLI! Great for automation, and it works on Linux, macOS and Windows
• Query subtitles in more than 60 different languages for documentaries, movies, TV shows and more...
• Query subtitles in multiple languages at once
• Query subtitles for multiple video files and folders at once
• Detect valid video files (using mime types and file extensions)
• Detect correct video titles by computing unique movie hash sums in order to download the right subtitles for the right file!
• If the video detection fails, a backup search using filename is performed
• Download subtitles automatically if only one is available, choose the one you want otherwise
• Download the subtitles file right next to the video file (need read/write permissions)
• Rename downloaded subtitles to match the video file. Possibility to add a language code (ex: movie_en.srt).

• Python 3 (you can use legacy versions to continue on Python 2)
• zenity (only needed for GNOME based desktop environments)
• kdialog (only needed for KDE based desktop environments)
• common unix tools (only needed for GUIs): wget & gzip (GUI subtitles downloading), ps & grep (GUI autodetection)

Quick install as a nautilus script, under GNOME desktop environment:

$ mkdir -p ~/.local/share/nautilus/scripts/
$ cd ~/.local/share/nautilus/scripts/
$ wget https://raw.githubusercontent.com/emericg/OpenSubtitlesDownload/master/OpenSubtitlesDownload.py
$ chmod u+x OpenSubtitlesDownload.py
