Upscale videos fast with sharp, smooth, cinematic results.

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 version of the workflow, you can upscale low-resolution or AI-generated videos into clean, cinematic-quality footage. It restores detail, refines textures, and keeps motion smooth without artifacts. Designed for post-processing and remastering, it gives creators clear, high-fidelity results. You can also optimize temporal consistency, ensuring realism across every frame. Easy to integrate into existing pipelines, it elevates your visual content effortlessly.
