Extend existing Veo video clips beyond per-call duration caps by stitching coherent continuations that preserve motion, lighting, and subject identity.

Core Features & Use Cases

  • Route to Veo 3-1 extend endpoints (extend-video and fast/extend-video) to create longer clips from a seed video.
  • Choose between high-quality extended output and faster, cost-efficient iterations for draft content.
  • Use cases include hero cuts, chained narrative shots, and iterative scene expansion while maintaining visual consistency.

Quick Start

Provide a seed video URL and a continuation prompt to the RunComfy CLI to generate an extended clip.
