Preparing MOV / WebM for a cleaner MIDI result
- Use a short source clip with steady audio levels and trim away setup, countdown, or conversation.
- A clear single melody, vocal, or instrument line usually needs less cleanup than a dense finished mix.
- Trim long silence and unrelated sections before uploading so the transcription focuses on the passage you need.
- Some MOV files contain several audio streams; the converter uses the first stream, so export the intended mix first when needed.
