This is one of the most animated live-action clips I've ever seen. The timing is simply perfect!
A few things I've noticed:
- Much of the charm here comes from the contrast between the busy, wild 7 seconds of the beginning, and the remaining 5 seconds of quiet aftermath.
- The dog detaches and leaves not at once, but gradually. It reminds me that the principle of arcs is much broader than we usually give it credit for: things tend to change direction over time, not in a single moment.
- Another gradient is his posture. He's hunched down for the first 6 seconds or so, then straightens in three beats:
00:06 - slightly straighter, the dog is further now
00:07 - almost fully upright, but his back is still arched forward - he's still inside the situation
00:10 - fully upright, spine arch reversed, he's out of the situation.
- His arm up when he says "you go" is clearly an act of pride and victory.
- For the first 10 seconds, the only thing in the world is that dog. This we see through change: when he feels the crisis to be over, he looks at the photographer - the rest of the world is relevant again
Kudos for Shuki Gamliel, who sent me the link.
