DeepSubX is a Dockerized application that extracts embedded subtitles and translates external subtitle files for movies and TV shows using the DeepL API. It provides a web UI for batch processing media folders and can optionally notify a Plex server to refresh its library after translations are added.

Key Features

  • Translate subtitle files (SRT, external subtitles) using the DeepL API
  • Extract embedded subtitles from video files and output translated subtitle files
  • Optional Plex integration to trigger library updates after translations
  • Web UI built with Vite and React for browsing and processing media folders
  • Configurable via environment variables and designed to run in Docker / Docker Compose

Use Cases

  • Translate entire movie and TV show libraries into a target language for local viewing
  • Automatically refresh a Plex media server after generating translated subtitles
  • Batch-process new releases or large collections of media files using a containerized workflow

Limitations and Considerations

  • Requires a DeepL API key (network access and API usage costs apply); no built-in offline/local translation models
  • Designed to run in Docker; manual setup without containers may require additional tooling
  • Focused on extraction and translation; it is not a full subtitle editor or advanced subtitle timing fixer

DeepSubX is suited for self-hosted media enthusiasts who need automated subtitle translation and simple Plex workflow integration. It emphasizes straightforward batch processing and containerized deployment for media collections.
