Runway Aleph

Runway Aleph is an AI video editing tool driven by text prompts. Instead of a timeline and keyframes, you describe the change and the tool performs it. The listed capabilities cover generating new camera angles from existing footage, removing objects from a video, changing the environment a scene takes place in, and applying styles and effects. It also supports green screen extraction and changing how a character looks. Alongside the natural language control, the page mentions detailed video control, so the simple prompt path sits above a more precise one. It says the tool can be used for free without logging in.

- Generate a new camera angle from footage you already have.

- Remove an object from a video without manual masking.

- Change the environment a scene takes place in.

- Apply styles and effects, or extract a green screen.

- Creators editing short-form video for social platforms.

- Marketers producing ad variations from one shoot.

- Anyone who needs a quick edit without editing software.

Processing takes time and depends on queue length and clip length, so do not plan a same-minute turnaround. Prompt-driven editing is not deterministic: the same description can give different results, so expect to retry and refine wording. Only edit footage you own or have the rights to modify, because altering someone else's video without permission is a problem. And because access needs no login, there is no project library or history, so download anything you want to keep immediately. Behavior may vary across browsers and devices, so test before production use and consult the help docs if errors appear.
