A single mediamix.
py, only ffmpeg is required.
Music is looped or trimmed to the voice, ducked under speech (sidechaincompress), loudness is normalised to −16 LUFS, with a fade-out; if the video is shorter, the last frame is held.
Subtitles from timed text, untimed text (split on pauses), an SRT file or optional Whisper.
pytest 34/34; the demo clip is 14.
