ly2video ~  GNU LilyPond Files Into Video

ly2video is a Python script which converts music represented by a GNU LilyPond file into a video containing a horizontally scrolling music staff which is synchronized with a MIDI-generated audio rendering of the music.

It is also possible to synchronize the video of the scrolling music notation with a previously recorded audio track of the same music, such as a live performance, even when the audio uses tempo rubato or is not precisely metronomic.
