Video Outpainting

agentspace-so/runcomfy-agent-skills

Spatial extension for video, powered by RunComfy's CLI and Wan 2-7 edit-video. You feed it a vertical clip and a prompt like "extend the canvas to 16:9 by adding matching environment on the sides" and it gives you horizontal output with the original action centered. Works well for aspect ratio swaps (TikTok to YouTube, square to wide) and quick social cuts. Seam quality is acceptable for most internal and social use but not hero delivery. For that, the skill points you at dedicated ComfyUI outpainting workflows like the LTX 2-3 graph, which the CLI can't reach directly. Honest take: prompt-driven spatial extension is still early and you'll notice the seams on close inspection, but it's fast and beats manual rotoscoping for non-critical work.

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.
