Runway Aleph 2
Runway Aleph 2 is a video editor from Runway in New York. It is not a text-to-video generator. You supply a source video and a prompt describing the change: relight, restyle, remove or replace an object.
Optional keyframe images and positions can pin a face, a product, or a wardrobe beat so it does not drift across the plate. A seed is available for reruns. Without keyframes, the prompt alone drives the edit.
What it's good for
Rewriting footage you already have. The light was wrong, the client hates the couch, an object needs to go. It will not invent a clip from a prompt alone. Duration and resolution follow the source more than a generate picker.
