How to use Erase and Replace

Step 1
Paint over image
Import an image from your computer or assets in Runway. Simply select a brush size and paint over the subject you’d like to replace.
Step 2
Write a prompt
Use your imagination to craft an original line of text. You’ll want to provide as much detail as possible for the best results — descriptors like “high definition” or “oil painting” indicate specific styles to match the context of your original photo.
Step 3
Click “Replace” to generate a new image! From there, the image can be downloaded to your assets, or locally to your computer.
