That YoutTube video is straight ripped off this guy, who posted his ORIGINAL light show on Kontraband several years ago:
Best Christmas Lights EVER at Kontraband

^^This one is the Trans Siberian Orchestra version, and the vid quality is better... since it's the original, lol!^^^
In the original version you can see it was probably done as still photography, and definitely edited after the fact to include the music.
