This is time-lapse footage of Ben taken overnight one evening, starting at around 5 p.m. and ending at around 6 the next morning. The camera shot one frame every 20 seconds, which means that 20 frames (a second of video) constitute about six minutes and 40 seconds of "real time."
The opening seconds include some stop motion experimentation with a stuffed duck, and some night-mode testing. About 3/4 of the way through, you'll catch Al changing him if you keep a close eye out.
