video-outpainting

video-outpainting is a skill for Claude Code from prime-skills/runcomfy-agent-skills. It costs 162 tokens per session (2,300 once invoked), scanned A, original, MIT.

A skill for extending the visible canvas of an existing video through RunComfy, a service for running video models. It can change the aspect ratio, such as from vertical 9:16 to horizontal 16:9, by adding matching surroundings around the original action.

In plain words
What is it for?
Use it to turn vertical videos into horizontal ones, make horizontal videos vertical, or add more environment at the sides or top and bottom.
Why use it?
It avoids cropping important content or reshooting a video for another screen shape. The original central action can remain while the scene is expanded around it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

video-outpainting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Video Outpainting

Extend a video's spatial canvas — uncrop vertically or horizontally, change aspect ratio while preserving the central action. This skill routes spatial extension through Wan 2-7 edit-video for prompt-shaped canvas changes, and points the agent at dedicated ComfyUI outpaint workflows when hero-grade seam quality matters.

# 1. Install (see runcomfy-cli skill for details)
npm i -g @runcomfy/cli      # or:  npx -y @runcomfy/cli --version

# 2. Sign in
runcomfy login              # or in CI: export RUNCOMFY_TOKEN=<token>

# 3. Spatially extend a video (closest CLI-reachable approach)
runcomfy run wan-ai/wan-2-7/edit-video \
  --input '{"video_url": "...", "prompt": "...extend canvas..."}' \
  --output-dir ./out

Pick the right model

Wan 2-7 Edit-Videowan-ai/wan-2-7/edit-video (default)

Prompt-driven video edit; accepts spatial extension language ("extend the canvas to 16:9 by adding matching environment on the left and right"). Wide enough quality for social and most internal uses. Pick for: aspect-ratio swap (vertical ↔ horizontal), social-cuts, uncrop where seam quality is acceptable. Avoid for: hero ad delivery with strict seam-quality requirements — use a ComfyUI outpainting workflow.

For broader video edit see video-edit.
