What is Runway Modify?
Runway Modify is a text-guided AI video editing tool powered by the Runway Aleph model. It transforms existing video clips based on natural language descriptions — changing scenes, objects, styles, and visual elements while maintaining temporal consistency. The model supports multiple aspect ratios from portrait to ultra-wide and offers advanced options like reference images and seed values for reproducible results.
Why Choose Runway Modify?
