Nice! Before, we had 2 different methods for generating video from LilyPond.

ly2video, by Adam Spiers, which makes a scrolling score.

MKVIDEO, by Knut Petersen, which makes a still score with notes changing 
color as they are played.

Now the video you've produced has a moving blue bar reminding me of the 
MuseScore software's playback function.

I think ideally these things would be combined into a best-hybrid 
product that's officially maintained within LilyPond or along-side as 
Frescobaldi is. Or whatever best serves the community around it.

As LilyPond moves towards using the cairo library for graphics output, I 
hope these video output methods (or something like them) is available 
beyond the transition. Video scores can be great learning aids for 
complex choral works. (Reminds me, I told someone I could get them one 
of "Worthy Is The Lamb" from Handel's Messiah by spring...)
