Runway Aleph

Runway Aleph is an in-context video model that edits an existing clip rather than generating from scratch. From a single source video it can add, remove, or transform objects, change the style or lighting of a scene, and generate new camera angles of the same moment.

Because the edits are made in the context of the original footage, motion and continuity are preserved, which makes it usable for real post-production tasks such as cleanup, reshoots, and variations without returning to set.

It is aimed at filmmakers, editors, and visual-effects artists who want to make substantial changes to footage they already have, and is available through Runway's platform.
