What makes a good AI video prompt?

A good AI video prompt is specific, visual, and action-oriented. It describes the subject, motion, camera movement, lighting, and style in concrete terms. Avoid abstract concepts and focus on what the camera would actually see.

How long should an AI video prompt be?

Optimal prompt length is 50-150 words. Too short gives the AI too much freedom (unpredictable results). Too long creates contradictions. Gemini Omni Flash supports up to 2000 characters, but 100-200 words typically produces the best results.

Do the same prompts work across different AI video tools?

The core principles are the same, but each model has strengths. Prompts that work on Gemini Omni Flash will generally work on other tools, though you may need to adjust for each models specific capabilities.

Should I include negative prompts?

Most current AI video generators do not support negative prompts the way image generators do. Instead, focus on clearly describing what you DO want rather than what you do not want.

How to Write AI Video Prompts: Tips, Templates & Examples for 2026

The Prompt Framework

Every effective AI video prompt answers five questions:

What is in the scene? (Subject)
What is happening? (Action/Motion)
How is the camera moving? (Camera)
What does the light look like? (Lighting)
What's the overall feel? (Style/Mood)

The Formula

[Subject] + [Action] + [Camera Movement] + [Lighting] + [Style/Quality]

Prompt Templates by Category

Product Commercial

A [product] on [surface/environment], [product motion], 
[camera movement], [lighting style], [atmosphere], 
product commercial quality, [duration]

Example:

A wireless earbud case opening in slow motion on a matte black surface, revealing glowing earbuds inside, smooth dolly-in with slight rotation, dramatic side lighting with cool blue accent, particles of light rising, 8K product commercial, 6 seconds

Cinematic Landscape

[Location/environment], [natural motion], [camera movement],
[time of day/lighting], [atmosphere], cinematic quality, 
[aspect ratio hint]

Example:

Vast desert dunes at golden hour, sand particles drifting in warm wind, drone shot slowly ascending to reveal endless horizon, warm directional sunlight casting long shadows, heat haze visible, cinematic widescreen quality

Fashion / Lifestyle

[Person description] in [setting], [action/pose], 
[fabric/hair motion], [camera style], [lighting], 
[editorial style reference]

Example:

A model in a flowing red silk dress standing on a rooftop at dusk, dress fabric billowing dramatically in wind, slow-motion hair movement, camera circling at medium distance, golden hour backlight with city lights below, high fashion editorial cinematography

Abstract / Brand Visual

[Visual elements] in [space/environment], [motion type],
[color palette], [texture/material], [mood], seamless loop

Example:

Liquid chrome and molten gold colliding in zero gravity, forming impossible geometric shapes, light refracting through translucent surfaces creating prismatic rainbow caustics, dark void background, extreme macro detail, satisfying visual, seamless loop

[Eye-catching hook], [dynamic motion], vertical format 9:16,
[bold colors/contrast], [energy level], social media optimized

Example:

Colorful paint splashing in extreme slow motion against pure white background, forming the shape of a sneaker, vibrant neon colors, high contrast, vertical format, energetic and eye-catching, social media style

Camera Movement Vocabulary

Use these specific terms for predictable camera behavior:

Term	Effect
Dolly-in	Camera moves toward subject
Dolly-out	Camera moves away from subject
Pan left/right	Camera rotates horizontally
Tilt up/down	Camera rotates vertically
Tracking shot	Camera follows subject movement
Crane shot	Camera rises or descends
Static	Camera doesn't move
Handheld	Slight natural shake
Orbit / arc	Camera circles around subject
Zoom in/out	Focal length changes

Lighting Keywords That Work

Rim lighting — Light from behind, creating edge glow
Volumetric light — Visible light beams through atmosphere
Golden hour — Warm, directional, low-angle sunlight
Neon — Colorful artificial light sources
Studio lighting — Clean, professional, controlled
Dramatic shadows — High contrast, moody
Soft diffused — Even, gentle, flattering
Backlit — Light source behind subject

Quality and Style Modifiers

Add these at the end of your prompt to influence output quality:

8K quality / cinematic quality / professional quality
shallow depth of field / bokeh
slow motion / 120fps feel
film grain / anamorphic lens
color grading: [warm/cool/teal-orange]

Common Mistakes and Fixes

Mistake	Fix
"A beautiful sunset"	"Golden hour sun setting behind mountain silhouette, warm orange sky fading to purple, time-lapse clouds"
"Make it look cool"	"Neon blue rim lighting, dark background, slow motion, cinematic color grading"
"A person walking"	"A woman in a black coat walking through rain-soaked Tokyo streets at night, neon reflections on wet pavement, tracking shot from side"
"Fast action"	"Extreme slow motion capture of water balloon bursting, droplets suspended in air, high-speed camera feel"

Iteration Strategy

First generation: Use your full prompt, evaluate the result
Second generation: Adjust the weakest element (usually motion or camera)
Third generation: Fine-tune lighting and atmosphere
Lock it in: Once you find a working formula, save the prompt for reuse

Platform-Specific Tips for Gemini Omni Flash

Duration: Start with 5s for testing, extend to 8-12s for final output
Aspect ratio: Choose before writing your prompt — it affects composition
Audio: Enable native audio for content that needs ambient sound
Seed: Use a fixed seed when iterating to keep similar visual elements
Resolution: Use 720p for final output, 480p for quick tests
