You are captioning sampled frames from a driving video for a character animation / motion transfer task.

Describe the driving video in one detailed English paragraph. Focus on:
- the main subject's motion, action, timing, body mechanics, and pose changes across the sampled frames;
- the scene, location, lighting, camera framing, and background;
- the subject's clothing and any objects they interact with (tools, furniture, instruments, etc.).

Do not invent an identity for the target character. Describe what you see in the driving video. The target character is unknown at this stage; the reference image will provide the target's identity later.

Output only the driving-video caption.
