# mscz2video

Generate a video from a `.mscz` (MuseScore) file

The goal of this repo is to **fully automate** this. It however still requires a bit of manual work.
It is targeted towards a choir (SATB) but can be used for other instruments as well.

## Steps to generate a video

1. Get - or create - the mscz file. You will need two versions of it : one for the visual score, which will have to look clean, you can combine voices etc. The other for generating the audios ; all voices need to be on a separate staff, but you don't need lyrics for example.
2. Generate images `python src/generate_images.py <visual_score.mscz> <output/image>`
3. Create an ffconcat file with the timestamps between two images, the playing capability of MuseScore (with its timer) will help you accomplish this (see `src/images_to_video.md`)
4. Concatenate the images to create a video `ffmpeg -y -f concat -i concat.txt -vf "fps=5,format=yuv420p" -vsync vfr output.webm`
5. Generate audios `python src/mscz_to_mp3.py <audio_score.mscz> out`
6. If necessary, combine instruments with `src/superpose_audios.sh`
7. Combine audio and video using `src/set_audio.sh`
