What it does
When an instructor drops a new lesson video into a shared Dropbox folder, this pipeline produces a complete localized package: a source-language transcript, translated `.srt` subtitle files, and dubbed audio tracks in each target language, all archived to R2 under a stable per-lesson key.
When to use it
Use it when you publish course content regularly and want localization to happen the moment a video lands, instead of batching it manually. Best for teams with a fixed set of target languages defined once.
How it works
- 1A new file in the Dropbox `/course-videos` folder fires the trigger.
- 2The video audio is sent to Hugging Face Whisper for source-language transcription with word timings.
- 3Branch on file type: skip non-video files, continue for `.mp4`/`.mov`.
- 4For each configured target language, the transcript is translated and timed into an `.srt` subtitle file.
- 5ElevenLabs generates a dubbed voice track per language from the translated text.
- 6All subtitle files and audio dubs are written to R2 under `lessons/{lessonId}/{lang}/`.
