Creating Slow Motion Videos with Runway ML: A Detailed Guide

The power of slow-motion footage in filmmaking is undeniable, from showcasing the intricacies of action sequences to emphasizing emotional moments. But what if you didn't capture your footage in high frame rates needed for slow motion? Fortunately, with the application of AI technology and tools like Runway ML, you can transform your regular footage into slow-motion marvels. Let's walk you through the process.

What is Runway ML?

Runway ML is an easy-to-use platform that harnesses the power of machine learning for creators, enabling them to use advanced AI models without any coding. It offers various capabilities, one of which includes the ability to create slow-motion videos from normal footage through frame interpolation.

Converting Normal Footage to Slow Motion: A Step-by-Step Guide

  1. Launch Runway ML: Open Runway ML on your computer and create a new workspace.

  2. Import Your Footage: Click on the 'Add Input' button to import the video file you want to convert into slow motion. Remember that Runway ML can handle video files up to 500MB in size.

  3. Choose AI Model: From the list of available AI models, select the one that fits your needs. For slow-motion video creation, 'DAIN' is the appropriate model to use. DAIN (Depth-Aware video frame INterpolation) is designed to generate intermediate frames in a video sequence to achieve slow motion.

  4. Configure Settings: After selecting the DAIN model, configure your settings. You'll need to specify the 'Time Steps' setting, which dictates how many frames will be interpolated between the original frames. A higher number will result in a slower slow-motion effect. For instance, setting Time Steps to 0.5 will double your video's length, while setting it to 0.25 will quadruple it.

  5. Run the Model: Click on the 'Run' button to start the frame interpolation process. The AI will work to create the new frames necessary for your slow-motion video.

  6. Preview and Export: Once the process is complete, preview your slow-motion video directly in Runway ML. If you're satisfied with the result, click 'Export' to save your new slow-motion video.


Runway ML provides an accessible route into the world of AI-enhanced video editing, making it possible for creators at all levels to harness the power of machine learning. With the platform's DAIN model, you can breathe new life into your footage, transforming everyday moments into breathtaking slow-motion sequences. As with all AI tools, the results can vary, but with quality source material and a bit of experimentation, you can create striking slow-motion footage with ease.
