SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Video outpainting fixes the need to uncrop, reframe, or change aspect ratios by extending the visual canvas beyond the original frame while keeping the central action intact.

Core Features & Use Cases

  • Aspect-ratio change (uncrop): Convert 9:16 vertical to 16:9 horizontal or vice versa while preserving the subject in the middle.
  • Prompt-shaped spatial extension: Route canvas expansion requests through the RunComfy CLI using Wan 2-7 edit-video.
  • Hero seam-quality option: Point to dedicated ComfyUI outpainting workflows when you require higher seam and motion-aware consistency for delivery.

Quick Start

Use the video-outpainting skill to extend an input video to a new aspect ratio by running the RunComfy CLI with an outpaint-shaped prompt.

FAQPage Schema
How do I convert a vertical video to horizontal without cropping the subject?

Video outpainting extends the spatial canvas beyond the original frame, allowing you to convert vertical videos to horizontal while keeping the subject intact. It applies prompt-shaped spatial extension to generate new environment details around the central action.

What is video outpainting for social media reframing?

Video outpainting is a spatial extension technique that expands a video's visual canvas to change aspect ratios. It uncrops footage for social media reframing while ensuring the central action remains preserved in the middle.

Can I use RunComfy CLI with Wan 2-7 edit-video to extend a video canvas?

Yes, you route canvas expansion requests through the RunComfy CLI using Wan 2-7 edit-video. You must provide JSON input containing the video_url and a prompt describing the environment to add and how to maintain central framing.

When should I use dedicated ComfyUI outpainting workflows instead of this skill?

You should point to dedicated ComfyUI outpainting workflows when you require higher seam and motion-aware consistency for final delivery. The skill serves as a fast solution for uncropping and extending the video canvas.

What do I need to provide in the JSON input for Wan 2-7 edit-video?

You need to provide JSON input containing the video_url and a prompt. The prompt must describe what environment to add during the spatial extension and how to maintain the central framing of the original video.
