如何写出真正有效的 AI 视频提示词

A great AI video starts with a great prompt. But "a dog running" gets you a generic clip, while "a golden retriever sprinting across a rain-soaked beach at golden hour, low tracking shot, lens flares" gets you something cinematic. The difference is structure.

This guide breaks down the 5-part prompt formula that consistently produces better AI video — whether you're using Seedance 3.0, HappyHorse, Veo 3.1, or any model.

The 5-Part Prompt Structure

Every strong video prompt contains five ingredients. You don't always need all five, but including most of them dramatically improves results.

1. Subject (主体)

Who or what is the focus? Be specific.

❌ Weak: "a person"
✅ Strong: "a woman in a red trench coat"

2. Setting (场景)

Where does it happen? Environment grounds the scene.

❌ Weak: "outside"
✅ Strong: "on a neon-lit Tokyo street at night"

3. Motion (运动)

What moves, and how? This is what makes it video instead of a photo.

❌ Weak: "walking"
✅ Strong: "walking briskly while glancing over her shoulder"

4. Camera (镜头)

How is it filmed? Camera language translates directly to AI output.

❌ Weak: (omitted)
✅ Strong: "low-angle tracking shot, slight handheld shake"

Common camera terms that work well:

| Term | Effect | |------|--------| | Tracking shot | Camera follows the subject | | Crane shot | Camera rises vertically | | Close-up | Tight framing on detail | | Wide shot | Establishes scale | | Dolly zoom | Dramatic perspective shift |

5. Mood (氛围)

The emotional texture. Lighting, color, atmosphere.

❌ Weak: "nice"
✅ Strong: "moody, volumetric fog, teal-and-orange color grade"

Putting It Together

Here's the formula as a template you can copy:

[Subject] + [action/motion] + [setting] + [camera] + [mood]

And a full example:

A weathered fisherman hauling a net onto a wooden dock, waves crashing below, golden hour backlight, slow dolly-in, warm cinematic tones with lens flare.

Model-Specific Tips

Seedance 3.0

Seedance 3.0 excels at coherent motion and multi-shot narrative. You can describe a sequence of actions and it maintains subject consistency. Lean into camera movement descriptions.

HappyHorse 1.1

HappyHorse 1.1 is fast and versatile for 4–12 second clips. Keep prompts focused on a single strong action — it shines when the motion description is clear and contained.

Veo 3.1

Veo 3.1 produces exceptional realism and detail in short clips (4–8s). Invest heavily in the mood and lighting descriptions; it renders atmosphere beautifully.

Common Mistakes to Avoid

Overloading the prompt. More words ≠ better. Stick to the 5 parts.
Vague motion. "Moving" tells the model nothing. Specify direction and speed.
No camera direction. Without it, you get a default flat angle.
Contradictory instructions. "Slow and fast" confuses the model.

Start Practicing

The fastest way to improve is to iterate. Write a prompt, generate, then refine one element at a time. Try the formula above in the text-to-video generator — you'll see the difference within a few attempts.

Happy prompting.
