Runway: Aleph 2.0

Runway Aleph 2.0 is an in-context video editing model from Runway. It applies text instructions and keyframe-guided edits across existing footage while preserving details that are not meant to change. It is suited for adding, removing, or replacing subjects and objects, changing backgrounds or outfits, relighting scenes, shifting weather or time of day, restyling footage, and expanding a shot to a new aspect ratio.
