Turns a grainy, low-resolution video clip into a cleaner, higher-resolution one
The problem it solves
You want to reuse an old clip, but it is so grainy and small that it looks broken on a modern screen.
For People restoring old footageVideo makers reusing low-res clips
- Before
- You live with the noisy clip or pay for an online upscaling service by the minute.
- After
- One template cleans up the noise and enlarges the clip on your own graphics card, with frames that stay consistent.

Overview
This is an official ComfyUI workflow template that restores and upscales one video with the 3B version of SeedVR2, an open model from ByteDance Seed that keeps frames consistent with each other. You load a clip, choose how many times larger it should be, and it saves a sharper video. You can trim a long clip first and work through it in shorter parts. ComfyUI offers to download the two model files, about 3.7 GB, the first time. It suits people restoring old footage or low-resolution recordings.
It uses the smaller 3B model, so the download is under 4 GB, and it restores each clip in one step rather than many.
Try these first
Start with the first one: it is a small task you can check easily.
- Open the template with its sample clip, keep the default settings and render it, then compare the result with the grainy input.First try · about 3.7 GB download
- Load [your video], turn on trimming and upscale only the first 5 seconds.
- Upscale [your video] two times and turn on color correction to match the original colors.

How it works
From the creator's documentation.
| Step | What happens | Data goes to |
|---|---|---|
| 1 · Model files | ComfyUI offers to download the two model files, about 3.7 GB, the first time | Your computer |
| 2 · Load and trim | You load a clip and can cut out a shorter segment to work on | Your computer |
| 3 · Restore and upscale | SeedVR2 3B removes noise and scales the video by the factor you set | Your computer |
| 4 · Save | ComfyUI saves the upscaled video | Your computer |
Good to know
Restore and upscale a short, degraded video clip with the official SeedVR2 3B Int8 graph. The template can trim a segment first, then upscales it and saves the new video.
Limits
- The template's own note warns that long inputs can run out of memory or slow down. Turn on trimming and upscale long videos in shorter segments, then join them.
- The two model files take about 3.7 GB of disk space, and the template needs ComfyUI 0.28.0 or newer.
