How to get the best out of Gen-4 Aleph (Video to Video)
Gen-4 Aleph (Video to Video) on Pixio is Runway's video-to-video model: you input existing video and a text prompt (and optionally a reference image) to restyle or transform the clip. Change the look (e.g. cartoon, painting), add or remove objects, adjust lighting, or guide the mood—while preserving motion and timing. Use it when you have footage and want to change its style or content, not generate from a single still.

Use it when you have footage and want to change its style or content, not generate from a single still.
Use this when
- You have existing video and want to change its style (e.g. oil painting, anime, sketch) with a text prompt or stylized reference frame.
- You need to add, remove, or replace objects or change lighting while keeping the original motion.
- You want Gen-4-level consistency—coherent characters, objects, and locations across the transformed clip.
- You're building a post pipeline with Runway: generate with Gen-4 image-to-video, then restyle or edit with Aleph, then 4K upscale.

Credits
Credits depend on duration and plan; video-to-video typically costs more per second than image-to-video. Check the model card in Pixio for current rates.
Why video-to-video fits restyle and edit
Gen-4 Aleph (Video to Video) doesn't create video from a still—it and changes how it looks or what's in it. The prompt (and optional reference image) drives the transformation; . Use it for artistic restyles (cartoon, painting, etc.), object/lighting edits, or to align footage with a new look. Combine with Gen-4 image-to-video for new shots and Gen-4 Upscale for 4K.
