Quick answer
An AI video prompt works best when it reads like a short shot brief: one subject, one setting, one camera move, three or four specific actions, and the look you want. Write it in plain sentences, in the order things happen. Put the most important action early, keep each clip to one continuous shot, and say what you do not want (for example “no cuts, no text, no logos”). Then check the clip against each action you asked for, and change one thing at a time when you retry.
Key takeaways
- Use a simple order: subject, setting, camera, actions, style, exclusions.
- Name the camera move, for example “the camera moves backwards in front of the subject”.
- Add 3–4 checkable moments so you can tell whether the model followed the brief.
- Keep one shot per prompt. Ask for cuts in separate clips.
- Refine by changing one element per retry and noting what changed.

In WorldofAI’s eight-model test, the winning prompt was long and specific, yet several models still left out a car splash or a head turn. That tells you two things: detail helps, and you need a way to check what you got.
This guide answers one question: how do you write an AI video prompt that models actually follow? It builds on our Kling 4.0 vs Seedance 2.5 comparison and the WorldofAI source video.
What makes an AI video prompt work?
A good AI video prompt is clear about what happens, where the camera is and what it should look like. Models handle short, concrete descriptions better than vague moods.
“A cool rainy city video” leaves almost everything to chance. “A slow backward tracking shot of a courier cycling through a rainy city street at night, neon reflections on wet tarmac” gives the model a subject, a setting, a camera move and a look.
Most current text-to-video models generate short clips, often 5 to 15 seconds, and some offer longer ones. In a short clip there is only room for a few actions, so choose them carefully.
What should an AI video prompt include?
Use these six parts, in this order:
| Part | What to write | Example |
|---|---|---|
| Subject | Who or what, with 1–2 fixed details | A courier in a yellow waterproof jacket |
| Setting | Place, time and weather | A busy city street at night, heavy rain |
| Camera | Shot type, movement and lens | Slow backward tracking shot, 35mm lens |
| Actions | 3–4 things that happen, in order | Stops at a red light, wipes rain off a phone |
| Style | Lighting and finish | Photorealistic, neon reflections, shallow depth of field |
| Exclusions | What you do not want | No cuts, no text, no logos |
💡 Tip: Repeat the fixed details of your subject (the yellow jacket, the white spacesuit) in every prompt in a series. It helps the model keep the character consistent between clips.
What is a good AI video prompt template?
Copy this template and fill in the brackets:
“A single continuous [shot type] of [subject with 1–2 fixed details] [doing the main action] in [setting, time of day, weather]. The camera [movement], keeping [subject] [framing]. [Action 1]. [Action 2]. [Action 3] before [final action]. [Style: lighting, realism, lens, depth of field]. No cuts, no text, no logos.”
Here is a filled-in example for a small business advert:
“A single continuous close-up tracking shot of a ceramic coffee mug with steam rising, on a wooden café counter in soft morning light. The camera slowly circles the mug from left to right, keeping it centred. A hand slides a saucer next to it. Sunlight moves across the counter. The steam curls towards the window before the shot ends. Photorealistic, warm tones, shallow depth of field, 50mm lens. No cuts, no text, no logos.”
Notice each action is a short sentence of its own. That makes it easier for the model to pick out, and easier for you to check.
Why add checkable moments to your prompt?
Checkable moments turn a vague result into a clear pass or fail. In the WorldofAI test, the prompt included a splash, umbrellas and a head turn. That is how the creator could say Seedance 2.5 looked gorgeous but missed two requested actions.
For your own prompts, pick three or four moments that matter to the shot and are easy to see. Then, when the clip arrives, tick them off:
- Did the main action happen?
- Did the camera move the way you asked?
- Did each named detail appear?
- Did the subject stay the same from start to finish?
If you want to compare several tools with the same prompt, our guide on how to compare AI video generators fairly before you pay turns these checks into a simple scorecard.
How do you write and refine a prompt, step by step?
- Write the one-line goal. For example: “a 10-second background clip of our café for an Instagram advert”.
- Fill in the six parts using the table above.
- Order the actions as they should happen in time, with the most important one first.
- Set the length and aspect ratio in the tool: 16:9 for YouTube and websites, 9:16 for Reels, TikTok and Shorts.
- Generate one clip and watch it at least twice.
- Tick off your checkable moments. Note which ones failed.
- Change one thing, such as moving a missed action earlier or making it more specific, and try again.
- Save the final prompt with the model name and settings so you can reuse it.
⚠️ Warning: Every retry usually costs credits. Set yourself a limit, such as three attempts per shot, before you start. If a model keeps missing the same action, try a different model rather than rewriting endlessly.
What mistakes stop models following your prompt?
| Mistake | Why it fails | Better approach |
|---|---|---|
| Too many actions | Short clips cannot fit them all | Keep to 3–4 actions per clip |
| Asking for cuts | Models struggle to plan edits | One shot per prompt; edit clips together after |
| Vague mood words only | The model has to guess | Describe what is visible: light, weather, movement |
| Changing the subject’s details | The character drifts between clips | Repeat the same 1–2 fixed details every time |
| Asking for words on screen | On-screen text often comes out garbled | Add text and logos in your video editor |
| Real people or brands | Likeness and trademark risks | Use original characters and your own branding |
🔎 Unconfirmed / rumour: Different models respond to wording differently, and the tools change often. Treat any template, including ours, as a starting point and test it on the model you actually use.

Frequently asked questions
How long should an AI video prompt be?
Long enough to cover subject, setting, camera, 3–4 actions, style and exclusions. That is usually 60 to 150 words. Beyond that, models often drop details.
Why does the AI video model ignore part of my prompt?
Usually there are too many actions for the clip length, or the key action is buried at the end. Move it earlier, make it a short sentence of its own, or try another model.
Should I describe camera movement in AI video prompts?
Yes. Name the shot type and movement, such as a slow push-in or a backward tracking shot. In the WorldofAI test, camera control was one of the clearest differences between models.
Can I add text or logos with an AI video prompt?
It is better not to. Generated text is often garbled. Add titles, captions and logos in your video editor instead.
Do I need a different prompt for each AI video model?
Start with the same prompt so you can compare fairly, then tweak it for the model you choose. Our guide on comparing AI video generators fairly explains how.
The bottom line
Write your AI video prompt like a shot brief: subject, setting, camera, a few clear actions, style and exclusions. Add moments you can check, change one thing at a time and save what works. Your next step: take one clip you need this week, fill in the template and run it once.
