Runway Aleph – an AI video editing model developed by Runway

What is Runway Aleph？

Runway Aleph is a powerful AI video editing model developed by Runway. It allows users to edit videos using simple text prompts—enabling fast and intuitive content addition or removal, style transformation, environment changes, and camera motion adjustments. With Aleph, users can easily remove unwanted elements from a video or transform a daytime scene into night, or convert a realistic video into a cartoon style. One of Aleph’s core strengths is its context-aware editing capability—it understands narrative flow and spatial-temporal relationships in videos, avoiding common editing artifacts and errors.

Key Features of Runway Aleph

Content Addition and Removal
Aleph can accurately identify objects in a video and supports adding new elements or removing unwanted ones. For instance, it can remove glass reflections or background clutter, or add falling cherry blossoms to a street interview scene.

Environment and Atmosphere Transformation
Users can change the environment, weather, or season of a video with a simple text command—turning a sunny scene into a rainy one, or converting daytime footage into night, giving the video a new narrative mood.

Style Transfer
Supports converting videos into artistic styles such as cartoons, oil paintings, or other visual aesthetics, while maintaining visual consistency. This is ideal for creative projects and brand storytelling.

Camera Motion Transfer
Aleph retains the original camera movements—such as pans, zooms, or tracking shots—when generating new content or perspectives. This is particularly useful for dynamic scenes, where maintaining the original motion rhythm enhances realism.

Green Screen and Lighting Optimization
Built-in green screen extraction doesn’t require professional equipment—AI automatically detects and isolates the subject. It also supports lighting adjustments to fit different scene requirements.
