Runway Aleph

Runway Aleph is a video-to-video transformation model that reskins existing footage using reference images while preserving the original motion, timing, and camera work.

Aleph operates in V2V mode: you supply an existing video clip and one or more reference images that define the desired visual style or character appearance. The model re-renders the video with the new look while faithfully following the original motion path, camera movement, and timing. This makes it powerful for style transfer, character replacement, and visual effects work where the underlying choreography must remain intact. It is not a general-purpose generator and does not support text-to-video or image-to-video from scratch.
