# SeedVR2: Video Restoration and 2K Upscale 
 
The finish step. Generated digital-human clips often come out soft — especially the hair, the eyelashes 
and fabric texture. This workflow restores detail and upscales to 2K so the talking head is not the 
softest element in the final edit. 
 
## What it does 
 
1. **Restore** — SeedVR2 reconstructs detail rather than simply interpolating pixels. Skin texture, 
 hair strands and fabric weave come back instead of turning to mush. 
2. **Upscale to 2K** — the restored frame is scaled up while keeping the reconstructed detail intact. 
3. **Temporal handling** — video mode processes frames with temporal context, so the restored detail 
 does not flicker frame to frame. 
 
## Why it matters in a talking-head pipeline 
 
The digital-human chain generates a low-resolution, somewhat soft shot. If you cut that next to 
sharp screen recordings or B-roll, the softness reads as a mistake. A restoration-and-upscale pass 
at the end normalises the whole piece. 
 
## Tips from the episode 
 
- Always restore the **final** clip, after you have settled the content — upscaling a shot you then 
 regenerate is wasted compute. 
- Watch the first and last frame for edge artefacts; give yourself a few frames of handles. 
- Over-restoration looks plastic. Compare against the source at 100% before you commit. 
- For very long clips, chunk the input and stitch, rather than one giant pass.

**About this workflow** 
 
Part of AI-KSK episode 329, which builds a talking-head digital human from a single image plus an audio track and finishes it at 2K. This is a ComfyUI workflow export: it references models that must be present in your ComfyUI environment. On RunningHub the cloud instance already has them installed. 
 
It is a tutorial workflow, not a packaged product. Node parameters are the ones used in the episode; adjust frame count, sample steps and resolution for your own hardware.
