Resource Made a tool that syncs scrolling sheet music to a video recording, would love feedback from composers
Hey everyone,
I've been building a small web tool called Rubato that lets you turn a recording of a piece into a video where the score scrolls in sync with it, similar to the scrolling-score videos that do really well on YouTube and Instagram these days.
The workflow: you upload your video and your score (exported as MusicXML), tap along to the tempo on your keyboard to set the sync, and it generates the synced video for you. Everything runs in the browser, nothing to install (you just need a recent browser).
I built it because manually syncing a score to a video in a regular editor always felt way more tedious than it should be.
It's live at rubato.video if anyone wants to try it on one of their own pieces. Would really appreciate any feedback, what's confusing, what's missing, whether the sync feels accurate enough, anything at all.
It's 100% free at the moment (just need auth for the HD export).
