- 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

- Requires the video to have captions enabled
- Falls back to auto-generated captions if manual ones aren't available
