This package exports 2 scripts:

• create-musescore-video - an opinionated utility to generate videos from MuseScore files
• score-util - used to generate videos with different audio tracks

All ideas and improvements are welcome via issues or pull requests.

Installation

npm i -g https://github.com/keijokapp/score-util

Requirements:

• Node 20 or later
• MuseScore 4 (possibly also works with earlier versions)
• ffmpeg and ffprobe

create-musescore-video

Usage: create-musescore-video input.mscz output.mp4

Creates a video file from MuseScore file. It does this by extracting SVG-s and playback synchronization info with mscore --score-media. It then creates frame images, each being an SVG with a cursor line drawn according to synchronization data.

Limitations:

• The generated video does not have audio. MuseScore does not support exporting audio using Muse Sounds via CLI. Audio could be manually exported and added to the video separately. Eg: ffmpeg -i silent-video.mp4 -i audio.wav -c:v copy -shortest video-with-audio.mp4 (-shortest is there because the audio exported from MuseScore is unnecessarily about 2 seconds longer than the playback)
• Encoding SVG-s to video is quite slow (tested to be <1x).
• Video frames are cut out directly from SVG-s, so if systems are too close together, they might not be separated cleanly.

These limitations are not relevant to current use cases but feel free to create an issue if they are for you.

score-util

Usage: score-util

Given that the utility is run in a working directory with the following structure

 /path/to/some-score
 ├─ some-score.mscz
 ├─ some-irrelevant-other-score.mscz
 └─ audio
    ├─ some-score.wav
    ├─ part1.wav
    └─ part2.wav

It generates the following files:

 /path/to/some-score
 ├─ some-score.pdf                -- PDF export of the score file
 ├─ some-score.mp4                -- video without audio
 └─ export
    ├─ some-score.mp4             -- video with audio from some-score.wav
    ├─ some-score (part1).mp4     --              ... from part1.wav
    └─ some-score (part2).mp4
