The Runway Image to Video (Gen3a Turbo) node generates a video from a single starting frame using Runway’s Gen3a Turbo model. It takes a text prompt and an initial image frame, then creates a video sequence based on the specified duration and aspect ratio. This node connects to Runway’s API to process the generation remotely.
