Return Synthesia-alike videos and make it free.
A lot of my fellow Musescore barkadas (even Pros) would actually complain that if they render piano videos in Musescore, the video would actually illustrate only the Sheet Music, not the Piano Tutorial (a la Synthesia) itself. So, if you would, we can request you to return Synthesia-alike videos and make it free.

Sounds like you are referring to the score-sharing website musescore.com, so you should go over there to that site to ask about this.
