Expand video scenes smoothly with consistent motion and perspective.
Who it's for: creators who want this pipeline in ComfyUI without assembling nodes from scratch. Not for: one-click results with zero tuning — you still choose inputs, prompts, and settings.

Why RunComfy first
- Fewer missing-node surprises — run the graph in a managed environment before you mirror it locally.
- Quick GPU tryout — useful if your local VRAM or install time is the bottleneck.
- Matches the published JSON — the zip follows the same runnable workflow you can open on RunComfy.
When downloading for local ComfyUI makes sense — you want full control over models on disk, batch scripting, or offline runs.
How to use (local ComfyUI)
1. Load inputs (images/video/audio) in the marked loader nodes.
2. Set prompts, resolution, and seeds; start with a short test run.
3. Export from the Save / Write nodes shown in the graph.
Expectations — First run may pull large weights; cloud runs may require a free RunComfy account.
Overview
With this advanced workflow, you can easily expand video frames beyond their original bounds while keeping motion and lighting continuity intact. It helps extend scenes horizontally or vertically, perfect for adjusting aspect ratios or creating panoramic effects. This process ensures visual harmony and smooth transitions across extended areas. The tool enhances creative control for cinematic storytelling. Ideal for designers and video creators seeking fluid, high-quality frame extensions.
