# Video prompting: control motion and camera

> Write effective video prompts for PornX that control subject motion, secondary movement, and camera behavior for consistent results.

Video prompts work differently from image prompts. The scene is already defined — by the first frame in Image-to-Video, or by the subject description in Text-to-Video. The prompt's job is to describe movement, not appearance.

## Prompt structure for video

Write elements in this order:

| Position | Element          | Example                                   |
| -------- | ---------------- | ----------------------------------------- |
| 1        | Subject motion   | `walking slowly forward`                  |
| 2        | Secondary motion | `hair blowing in the wind, dress flowing` |
| 3        | Camera movement  | `slow zoom in, steady camera`             |
| 4        | Lighting or mood | `soft natural light, warm tone`           |

Keep it short. Four to eight terms produce more consistent results than long descriptive paragraphs.

## Motion terms that work

**Body motion:** `walking forward, turning head slowly, looking toward camera, sitting down, leaning back, raising arms, subtle breathing motion, blinking`

**Secondary motion:** `hair blowing, dress flowing, water rippling, leaves moving, smoke drifting`

**Camera:** `slow zoom in, slow zoom out, steady camera, slow pan left, slow pan right, slight camera shake, pull back, push in, orbit around subject`

**Pace:** `slow motion, normal speed, gentle, subtle`

## Good vs bad video prompts

**Bad:** `beautiful woman, soft light, photorealistic, high quality` — this describes an image, not motion. The model produces a near-static clip.

**Good:** `slow pan right, subject turns head toward camera, hair moving gently, steady handheld camera feel, warm soft light`

**Bad:** `running, jumping, spinning, dancing, waving, laughing` — too many simultaneous actions. The model can't resolve them and produces chaotic or distorted motion.

**Good:** `walking slowly forward, slight sway in movement, camera pulls back steadily`

## Image-to-Video vs Text-to-Video prompting

**Image-to-Video** — the scene is fixed. Focus entirely on motion and camera. Don't redescribe the subject or setting.

**Text-to-Video** — the scene is not fixed. Open with a brief subject and setting description, then move into motion and camera terms. See [Text-to-Video](/video-generation/text-to-video).

## Tips

* One primary motion per prompt — describe one main action and let secondary motion support it
* Add camera movement explicitly — without it the model defaults to a locked, static camera
* Avoid conflicting directions — `zoom in` and `pull back` in the same prompt cancel each other out
* Subtle motion prompts produce more stable output than large movement prompts — `slow turn` beats `spinning around`
* If the output is too static, add `continuous motion, fluid movement` to the prompt
