AI Video Prompt Composer
Turn one scene into a clear video brief. Combine action, camera, lighting, timing and continuity, then edit the result.
Your scene
No sign-up. Prompt text stays in this page. This tool assembles text; video generation happens in the model you choose.

Your editable prompt
Set duration and ratio in the generator too. Model behavior varies; this builder does not call a video API.
Add your scene or load an example to begin.
If your model has no negative field, rewrite the main prompt positively and omit unsupported settings. Copying a prompt does not generate a video.
How to use this builder
- Define one shot. Name the subject, starting pose and reason for the movement. Use reference images you own or have permission to use.
- Choose a small motion budget. Combine one primary action with one camera move. For a face close-up, begin with a locked camera and subtle performance.
- Build, then edit. Remove conflicting instructions. Keep timing within the selected duration and change the output text if your model expects a different format.
- Generate and review. Set supported controls in the video service. Inspect identity, eyes, hands, background and final frames before using the clip.
Eight starting points, different production choices
Social and product clips
TikTok and YouTube Shorts use a portrait composition with one readable action. Product demo separates the reveal, demonstration and final hold. App promo recommends compositing real screenshots so labels stay legible.
Performance and atmosphere
Cinematic uses one camera path. Talking character identifies the separate audio/lip-sync step. Seamless loop specifies endpoint continuity. Atmosphere keeps the camera still while a small environmental motion carries the shot.
Worked example: a product demonstration
Start with a cream desk lamp and one switch. Request one switch action, a short forward camera move and a steady illuminated end pose. Keep the lamp proportions and brass material unchanged.
Load Product demo to see the filled brief. If the lamp bends during the camera move, lock the camera and test again. If a label needs to remain exact, add it later as an overlay or animate the original product image in an editor.
Keep the same reference, model version, duration and resolution when comparing prompt revisions. A clearer prompt reduces ambiguity; it does not guarantee a better render.
Limits to plan around
- This is a deterministic text builder, not a video generator, model evaluator or quality score.
- Long gestures, simultaneous camera moves and changing backgrounds can increase temporal errors. Simplify after a failed test.
- Negative prompts, exact durations, ratios and audio controls depend on the selected model. Check its current documentation.
- Requested consistency and matching loop endpoints still require frame-by-frame review. No preset guarantees identity, realistic anatomy or a seamless loop.
- The builder does not store inputs or send them to a generation API. Normal site analytics and cookie settings are described in the privacy policy.
Frequently asked questions
Is this free to use?
Yes. Building, editing and copying text here is free. A separate video generator may charge credits or require hardware.
Which video models does it support?
The output is plain text with model-neutral sections. Enter a model name as a delivery note, then adapt the text and settings to that model. This is not an API integration.
Why is the negative prompt separate?
Some generators accept a dedicated negative field; others do not. Use that field only when supported. Otherwise describe the desired stable behavior in the main prompt.
Can I edit the generated prompt?
Yes. Both result boxes are editable. Copy uses your current edited text. Clicking Build prompt again replaces the results with a fresh version from the form.
Will a six-second prompt produce exactly six seconds?
Only if the chosen generator supports that duration and you set it there. Text is a creative instruction, not an export setting.
