The Runway Image to Video (Gen4 Turbo) node generates a video from a single starting frame using Runway’s Gen4 Turbo model. It takes a text prompt and an initial image frame, then creates a video sequence based on the provided duration and aspect ratio settings. The node handles uploading the starting frame to Runway’s API and returns the generated video.
