SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Video editors need to extend a clip's visible area or adjust aspect ratio without re-shoots, while keeping the central action intact and coherent.

Core Features & Use Cases

  • Extend the video spatial canvas by prompting the model to add matching environment to the left and right to reach a target aspect ratio (e.g., 9:16 to 16:9).
  • Route through Wan 2-7 Edit-Video for CLI-based extension or redirect to dedicated ComfyUI outpainting workflows for hero-quality seams.
  • Use cases include social clips (TikTok/YouTube Shorts), tutorials, and marketing videos where framing must remain centered.

Quick Start

Prompt Wan 2-7 Edit-Video to extend the canvas to 16:9 while preserving the central action.

FAQPage Schema
How do I change a video aspect ratio from 9:16 to 16:9 without cropping the central action?

To change a video aspect ratio from 9:16 to 16:9, video outpainting spatially extends the canvas by generating matching background environments while preserving the central action and maintaining frame coherence.

What is the best way to extend video frames for TikTok or YouTube Shorts without visible seams?

The best way to extend video frames for social clips without visible seams is routing through dedicated ComfyUI outpainting workflows, which provide hero-grade seam quality and coherent background extension.

Do I need RunComfy CLI and Wan 2-7 to extend a video canvas via prompting?

Yes, extending a video canvas via prompting requires RunComfy CLI and the Wan 2-7 edit-video model to execute the spatial outpainting and generate the extended environment.

Can I use ComfyUI workflows for higher quality video outpainting seams?

Yes, you can redirect the video outpainting task to dedicated ComfyUI workflows to achieve hero-grade seam quality, ensuring the extended background remains visually coherent with the original frames.

When should I use prompt-driven video outpainting instead of re-shooting a clip?

Use prompt-driven video outpainting when you need to adjust framing or extend the visible area of social clips and marketing videos without re-shooting, provided the central action remains centered and coherent.
