With timestamps:
uv run scripts/get_transcript.py "VIDEO_URL_OR_ID" --timestamps

Supported URL Formats

Output
- CRITICAL: YOU MUST NEVER MODIFY THE RETURNED TRANSCRIPT
- If the transcript is without timestamps, you SHOULD clean it up so that it is arranged by complete paragraphs and the lines don't cut in the middle of sentences.
- If you were asked to save the transcript to a specific file, save it to the requested file.
- If no output file was specified, use the YouTube video ID with a
-transcript.txtsuffix.
Notes
- Fetches auto-generated or manually added captions (whichever is available)
- Requires the video to have captions enabled
- Falls back to auto-generated captions if manual ones aren't available
