# 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.
