SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill extends existing video clips beyond their original duration while preserving subject identity, motion, lighting, framing, and visual continuity.

Core Features & Use Cases

  • Quality-based routing: Choose between Veo 3-1 Extend for hero-quality results and Fast Extend for lower-cost iteration.
  • Narrative chaining: Build longer, shot-by-shot sequences by feeding each generated clip into the next extension.
  • Prompt guidance: Describe only the next action, anchor the camera explicitly, and keep each extension focused on one main beat.
  • Use Case: Turn a short Veo clip into a longer continuous scene or develop a multi-shot narrative from a single seed video.

Quick Start

Use the video-extend skill to continue the user-provided video with a prompt describing what should happen next.

Frequently Asked Questions about video-extend

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I extend a Veo video clip without losing subject identity or lighting consistency?▼

Video continuation preserves subject identity, motion, lighting, and physics by feeding an existing source video URL and a continuation prompt into the extension endpoint to generate longer continuous footage.

What's the best way to build a multi-shot narrative sequence from a single generated video?▼

Narrative chaining builds longer sequences by feeding each generated clip into the next extension, keeping each prompt focused on one main beat and anchoring the camera explicitly.

Do I need RunComfy CLI access to use Veo video continuation endpoints?▼

Yes, Veo video continuation requires an accessible source video URL, a continuation prompt, RunComfy CLI access, and valid RunComfy authentication to route requests through standard or fast extension endpoints.

When should I use Veo 3-1 Extend versus Fast Extend for video generation?▼

Veo 3-1 Extend routes to hero-quality results for final footage, while Fast Extend enables lower-cost iteration, allowing you to balance quality and cost across your video extension workflow.

Can I extend an existing video by describing only the next action in the prompt?▼

Prompt guidance for video extension works by describing only the next action, anchoring the camera explicitly, and keeping each extension focused on one main beat to maintain visual continuity.

Does video extension maintain consistent motion and framing across chained clips?▼

Video extension maintains consistent subject identity, motion, lighting, framing, and visual continuity across chained clips by applying continuation prompts to the source footage sequentially.
