Between the Bars

I just recently found out about this amazing project called LaBlogotheque that's been going on for a few years. This gorgeous video of Chris Garneau playing Elliott Smith's "Between the Bars" looks and feels like a painting somehow (reminds me of Courbet). It got me thinking, again, about the possibilities of using video as a painting reference. What would happen if you tried to paint from a video? If you tried to paint from an infinite 2D loop? And how would this differ from painting from a photograph and painting from life?
