|A Claude Code skill for extending or continuing existing video clips using Google Veo 3-1 extend-video endpoints via the RunComfy CLI, enabling shot-by-shot narrative chaining with consistent motion, lighting, and subject identity.
Overview
Video Extend is a Claude Code skill that continues existing video clips beyond their original duration using Google Veo 3-1's extend-video endpoints through the RunComfy CLI. It supports both a high-quality default endpoint and a faster, lower-cost variant for iterative drafts. The skill is designed for building longer narratives shot-by-shot from a single seed clip, maintaining consistent motion, lighting, and subject identity across extensions.
Key Features
- Two quality tiers: Full Veo 3-1 Extend for hero-quality final delivery, and Fast Extend for cost-controlled iteration and multi-shot drafts
- Shot-by-shot chaining: Feed the output of one extend call as input to the next, enabling narrative sequences built from a single seed clip (recommended 3-5 seconds per extend for identity consistency)
- Continuation-focused prompting: The source video provides identity, lighting, and framing; the prompt describes only what happens next, with explicit camera anchoring to prevent drift
- Simple CLI workflow: Install via npm, sign in with
runcomfy login, and run extends with a singleruncomfy runcommand specifying the source video URL and continuation prompt
Who is this for?
- Video creators who need to extend short Veo clips past the per-call duration cap (e.g., 8s to 16s)
- Content producers building chained narrative sequences shot-by-shot from a single starting clip
- Teams iterating on video compositions who want to draft with Fast Extend before committing to full-quality renders
