Runway Gen-4 Aleph (commonly referenced as gen4_aleph) is Runway’s in-context video editing + video-to-video generation model built on the Gen-4 family. Aleph was announced by Runway as a major extension to Gen-4 that lets users edit, transform and regenerate parts of an existing video (object removal/insertion, relighting, new camera angles, style/lighting changes) using simple text prompts and optional reference images.
Basic features (what gen4_aleph does)
- Video-to-video editing: Add, remove or replace objects and characters in a clip.
- Extend a story by generating the next shot that follows the input sequence.
