How to write better AI video prompts
Subject
Name one clear subject and one clear action. "A lone engineer walking toward a jet" beats "an amazing scene with technology".
Environment
Describe the space, materials and atmosphere: wet concrete, drifting dust, a hangar door open to a storm. Environment carries most of the realism.
Camera movement
One movement per shot. A slow push in builds tension; an orbit reveals scale; handheld adds documentary urgency. Combining them confuses the model.
Lighting
Lighting decides the mood before anything else. Golden hour reads as warm and nostalgic; hard dramatic light reads as tense and industrial.
Motion
Specify how things move — slow, deliberate, drifting, sudden. Models default to unnatural speed unless told otherwise.
Realism
Ask for natural physics, accurate reflections and detailed textures, and explicitly exclude what you don't want: text overlays, warped hands, watermarks.
Aspect ratio
Choose before you write. 9:16 needs vertical composition and tight framing; 16:9 rewards wide establishing shots.
