Merry Christmas - amazing Christmas lights
I have my own theory, but watch the video first before reading any more, and see what you think.
Fantastic, well done. I'm afraid I don't know who made this clip, but they have done a great job. I would love to see the original quality video to take a closer look at how it was done.
My theory is that the video creator has taken many still pictures of the house, with different light combinations switched on. It is then a fairly straight-forward (but time-consuming) process to edit the pictures into the correct order, and then synch it with the music.
This means that it is really more of an animation. You would also have to add a quick crossfade between each picture to give the impression of lights going on and off.
All in all, technically excellent. My only comment would be that if it was half as long, or even less it would have more punch. It just goes on a bit too long for me.
