Runway Aleph 2.0
Runway Aleph 2.0 is for transforming existing footage. Use it when you already have a source clip and want to restyle, alter, or reinterpret it with a text prompt and optional image guidance.
Best for
- video-to-video
- restyling footage
- source clip transforms
- image-guided edits
Use when
- You have an existing video that should remain the motion base.
- You want to change the look, setting, wardrobe, lighting, or style of a clip.
- You need a source-video model rather than a new video generator.
Avoid when
- You do not have a source video.
- You need text-to-video or image-to-video from scratch; use Runway Gen-4.5.
