Written by AIAnimation - January 31, 2024

Comprehensive Description and Analysis

AI and animation have been rapidly evolving, and the field of video generation is no exception. Recently, Runway ml released their new multi motion brush tool, which allows users to paint on an image and direct the motion in the AI generation. With the update to the motion brush, users can now apply five coats of paint to dictate the direction of different elements in a scene. In this article, we will explore the process of using the motion brush and showcase various outputs generated using this tool.

Introduction to Runway ml Gen 2

In order to get started with the new multi motion brush tool, we need to access Runway ml Gen 2. This version of the software provides a user-friendly interface and numerous controls for manipulating the AI-generated motion. Once we have uploaded an image, we can begin using the motion brush to add direction and motion to different elements within the scene.

Using the Motion Brush

When using the motion brush, we are presented with a user interface that offers five different brushes to choose from. These brushes can be applied to various parts of the image to control the motion. For example, brush one can be used to add motion to the protagonist, while brush two can be used for flowing petals in a vortex. Each brush can be customized with different motion settings such as horizontal, vertical, and ambient motion.

Adjusting the Brushes

It's important to note that if we paint over a certain area with a new brush, it will replace the previous motion applied. Therefore, we should carefully select the areas we want to modify and adjust the brush size and motion settings accordingly for each brush. By experimenting with different combinations of brushes and motion settings, we can create unique and dynamic animations.

Saving and Generating the Animation

Once we are satisfied with the motion applied using the motion brush, we can save our changes by adding a description and text prompt. Additionally, we have the option to adjust the camera motion, such as zooming in or out. After saving our changes, we can generate the animation and view the output.

Analysis of Generated Outputs

The generated outputs using the motion brush tool can vary in quality and accuracy. In some cases, the motion applied may not closely follow our guidance. However, by adjusting the motion rates and experimenting with text prompts, we can potentially improve the output. It's important to note that these limitations are not unique to Runway ml, as other AI-generated animations may also have similar issues.

Exploring Different Images

In order to showcase the capabilities of the motion brush, we have tested it with a selection of different images. The results demonstrate the versatility and potential of this tool in creating visually stunning animations. By combining multiple brushes and experimenting with different images, users can unlock endless creative possibilities.


The new multi motion brush tool in Runway ml Gen 2 offers exciting opportunities for AI-driven video generation. With the ability to apply five coats of paint and direct the motion of different elements in a scene, users can easily create dynamic and captivating animations. Although there may be some limitations and room for improvement, the overall potential of this tool is impressive. AI and animation continue to evolve, and it's exciting to be a part of such advancements in video creation.
