Edit on GitHubThe Runway First-Last-Frame to Video node generates videos by uploading first and last keyframes along with a text prompt. It creates smooth transitions between the provided start and end frames using Runway’s Gen-3 model. This is particularly useful for complex transitions where the end frame differs significantly from the start frame.
