Can I generate videos in 4K?


Generative video outputs are created in 720p, but can be upscaled to 4K. To upscale a generation, follow these steps:

  1. Create a video output inside a generative session
  2. Once the output has finished generating, select the Upscale to 4K (Screenshot 2025-07-20 at 6.17.58 PM.png) option beneath the completed generation
  3. The upscaled output will appear as a new generation 

To upscale uploaded videos (up to 40 seconds) not generated in Runway, you can use the Upscale App: Creating with Apps.

Additionally, exporting in 4K from a Video Editor Project will not upscale or change the resolution of non-4K footage. 

For further information on resolution settings, please see Changing the aspect ratio and resolution of your generative videos.
