#### **Copy-and-paste prompts**

```
"Fashion editorial close-up video: lower body mid-run on a sunlit walkway with diagonal shadows; vivid red knee-high socks with fluttering ribbon, glossy black Mary Jane kitten heels; elegant and playful mood; strong motion blur, shallow depth of field, warm film grain, high contrast, minimalist background."
```

```
"A high-energy action motion sequence: capture a subject mid-movement as if frozen in time, then released back into motion. Begin with a moment of suspension — the body in mid-air, hair and fabric pulled upward — then flow into the follow-through of impact or landing. Cinematic realism with strong directional light, high shutter speed look for clarity, natural motion blur trailing behind the limbs. Camera: dynamic tracking at 35mm, shifting from a low angle to eye level, emphasizing intensity. The sequence should feel like a compressed burst of energy — one decisive action visualized across just a few seconds."
```

```
"A white deer stands on a rocky hilltop under a dark blue sky. The camera zooms rapidly towards the deer's face. The deer stares directly at the camera, its white fur distinct against the rocks. Shadows play across its antlers as the camera moves closer."
```
