Runway
prompt generator.

Runway’s video models respond best to prompts that lead with motion: how the camera moves, then what the scene is, then the details that matter. Clear, direct sentences beat long lists of adjectives.

Runway doesn’t use negative prompts — writing “no blur” can even add blur — so the generator phrases exclusions positively, for example “smooth, stable motion” instead of “no jitter”.

Example outputNeon street walk
Tracking shot following the subject: an original fictional adult man in his 30s on a city street at night, rainy, wet reflections. He walks toward the camera through the rain, hands in his jacket pockets and water dripping from his hair, slows as a neon sign flickers beside him, then glances back over his shoulder. Throughout: natural blinking and breathing, rain falling steadily, background lights glowing and flickering softly. He wears a leather jacket outfit. Neon colored lighting, mixed warm and cool. Photorealistic, cyberpunk, teal and orange cinematic grade, teal, neon purple and black palette, natural real-time pacing. Live-action, photographic footage, not animation or CGI. Natural skin texture with visible pores. A clean frame with no text, logos or watermarks. Smooth, stable motion with consistent faces and anatomy.

How to write better Runway prompts.

01

Start with the camera

Opening with the movement (“Slow push-in:” or “Tracking shot:”) tells Runway how the shot should feel before anything else.

02

Describe, don’t negate

Say what you want to see. Positive phrasing avoids accidentally adding the thing you wanted to remove.

03

Image-to-video: prompt the motion

When you start from an image, the frame already sets the look — keep the prompt about the movement and the action.

04

One action per clip

A single clear action reads better than several events squeezed into a few seconds.
