A small dance after you arrive
The scene is arrival. Someone is home, and the pet in the photo takes a short dance that reads as a small reassuring hello. That is a way of casting the clip, not a second video with a hallway and a door. The movement underneath is the performance.
Keep the caption as modest as the dance. A brief, playful all-clear fits. Do not turn it into a report that an animal was worried, lonely, or soothed. You are placing a coat into a fixed piece of movement.
