Change Video Background: Replace Any Backdrop Instantly with AI

Yes, the Change Backdrop app is available on Unlimited Explore mode. You can use this app to change the backdrops of your videos without consuming credits when using Unlimited Explore.

The Change Backdrop app costs 15 credits per second.

All Apps are available to Runway users on a Standard plan or above. Each App uses credits similar to regular Runway generations, so you can start using Apps immediately with your existing plan.

For best results, use high-quality image or video inputs to avoid morphing or artifacts in your outputs. Start with simple, direct prompts instead of detailed or overly complex prompts. Prioritize describing what you would like to see happen in your output (e.g. "place the object in a bright, sunlit forest") instead of using negative prompting (e.g. "place the object in a forest that isn't dark").

Yes, you can use multiple Runway Apps on one image or video to create more complex effects. To use multiple Apps in sequence, simply download the output from your first App generation, then upload that result as the input to your next App. This allows you to combine effects like removing an object from a video and then changing the video background in separate steps.
