But due to its complexity, new users may not fully know how to use it. If you're also one of the Runway users who are struggling to use Motion Brush, then this guide is what you need. This guide provides easy-to-follow instructions on how to use Runway Motion Brush. Read on to find them out!
What Is Motion Brush in Runway?
First, an introduction. As the name implies, the Motion Brush is a feature of Runway that is designed all around motion and movement. It's accessible with its Gen-2 model.
Runway's Motion Brush allows the users to essentially draw over the elements and subjects in the photo that they want to see moving (just like using a magical paint brush), and then Runway makes those pieces move. Moreover, its multi-motion brush feature allows you to select different elements and assign different movements to them.

With the power of Motion Brush, you can breathe life into static images, with remarkably lifelike results. You can make clouds or mist slowly float across a landscape, or a row of animals faces into different directions.
How to Use Motion Brush in Runway
The Motion Brush has a lot to offer, but if you’ve not used it before, you may be cautious or confused about how to make the most of this tool. With that in mind, here’s a complete step-by-step guide of how to use Motion Brush in Runway, with easy to follow instructions, perfect for beginners.
Step 1: Go to the Runway Dashboard and Find Motion Brush
First you need to log into Runway and go to its dashboard, and click Start a new session.
Then choose Gen-2 as the working model and then select Motion Brush.
Step 2: Upload Your Image
You can either upload one of your own, by either clicking the “Upload a file” button or dragging and dropping your image onto the window, or you can use the text-to-image capacities of Runway to make your own image from a prompt. The choice is yours.
Step 3: Use the Brushes to Select Elements to Move
Once your image is loaded in, use the brush draw onto the image to select the elements or subjects you want to see moving.
Runway offers five motion brushes, allowing you to select five different areas to apply different motions.
Each brush has an adjustable size. And the Auto-detect area option can help you instantly select an element without spending time drawing the area manually.
Step 4: Set the Movement Direction and Speed
Once you’ve selected the part of the picture you want to see moving with the Motion Brush, you can use the three sliders at the bottom right of the screen to set the style of movement.
There’s a Horizontal slider for side-to-side movement, a Vertical slider for up and down movement, and a Proximity slider for movement towards or away from the camera. There's also an Ambient (noise) slider, which allows you to add randomness to above motions to simulate natural movements. Adjust each slider as desired.
Note that the further you extend each slider, the faster the movement will be. So, if you want to see something move to the right really quickly, shift the horizontal slider to the right as far as it will go.
And if you have used multiple brushes in the previous step, you'll need to set these movement settings for each brush.
Step 5: Generate and Watch/Share the Video
When you’ve locked in the areas you want to see move and set the desired movement speed and direction, simply click the “Generate” button to confirm your changes and generate the videos exactly as you intended. You can then watch, download or share the animated images as you like.
