Use Youka to create a karaoke video from /path/to/song.mp3. Transcribe the lyrics in English, use a clean karaoke subtitle style, export the final video in 1080p, and save it as ./karaoke.mp4.

Use Youka to create a karaoke video from https://example.com/song.mp4. If URL dependencies are missing, install them first. Then transcribe the lyrics automatically, use a clean karaoke subtitle style, export the final video, and save it as ./karaoke.mp4.
