Runway ML's Motion Brush Feature: Animate Your Images Like Crazy

Ever wished you could bring a bit of motion to those static images in your posts? Well, buckle up, because Runway ML has just rolled out a tool that's about to change the game! The new Motion Brush feature allows you to literally brush motion into any part of an image, creating a dynamic four-second video that can add a punch to your visual content. From cloud animations to bustling cityscapes, the possibilities are endless. Today, we’re diving deep into this feature—how to use it, the cool effects you can create, and why it’s a game-changer for content creators everywhere.

What is Runway ML's Motion Brush?

Runway ML has been at the forefront of AI video editing technology, providing tools that convert text and images into video content effortlessly. The latest addition to their arsenal is the Motion Brush feature, which is part of their Gen 2 model, currently in beta. This feature stands out because it lets users selectively animate parts of an image by simply brushing over them.

How the Motion Brush Works

Imagine you have a still image of a serene landscape. With Runway ML's Motion Brush, you can animate the clouds drifting across the sky or a river flowing through the scene. Here's how you can start using this feature:

Visit Runway ML: Go to the official Runway ML website and sign up for a free account. You'll receive a limited number of credits to start experimenting with, no credit card required.

Choose Your Image: You can upload your own image or select from pre-loaded options available on the platform. For this demo, let's say we choose an image of a landscape.

Select the Motion Brush Tool: In the tools section, click on the Motion Brush feature.

Brush Your Image: Use the brush to paint over the area you want to animate, such as the clouds or the water.

Adjust Settings: Set the direction of the motion (horizontal or vertical) and the intensity. You can also play with the brush size and eraser to fine-tune your animation.

Generate and Preview: Once you're satisfied with your settings, generate the video. You'll get a four-second clip showcasing your animated image.

Edit and Extend: If you want a longer video, you can extend the clip up to 16 seconds by generating additional sequences.

In this example, we animated the thunder and rain to create a dynamic weather effect, enhancing the overall mood of the scene. Additionally, we subtly adjusted Pikachu's expression to give it a mischievous smile, adding a touch of personality and depth to the character.

Practical Applications for Content Creators

The Motion Brush feature isn't just a fun tool; it has practical applications across various fields:

  • Social Media Engagement: Enhance your posts on platforms like Instagram and TikTok with dynamic visuals that stand out in a sea of static content.

First Impressions and User Feedback

I recently tried out the Motion Brush for myself, and the results were impressive. The tool is intuitive and responsive, making it easy for beginners and professionals alike to add a dynamic element to their images. The ability to control the motion's direction and intensity allows for customization that can suit any creative vision.


Runway ML's Motion Brush feature is a groundbreaking addition to the world of AI-driven content creation. It's easy to use, versatile, and opens up a new realm of possibilities for animating static images.
