Advanced Runway Pormpt Guide

Runway Gen-2 and Gen-3 respond best to prompts that clearly separate the subject, the style, and the camera movement. Unlike image generators, video generators need to know how things move.

Tips for Gen-3 Prompts

  • Structure: [Subject Action] + [Environment] + [Style/Lighting] + [Camera Movement].
  • Motion Buckets: Gen-2 allows you to control motion intensity from 1 to 10. Use high numbers for action scenes, low numbers for portraits.
  • Negative Prompts: Just like images, use "--no blur, distortion, morphing" to clean up your video generations.
