# SeedVR2 I2I Upscaler

## Summary

Practical `SeedVR2` image-to-image upscaler and restoration workflow from the `wizdroid/comfyui-workflows` pack. This is the kind of workflow you keep around when you want cleaner detail recovery, not just a bigger image.

## Model Family

- `seedvr2`

## Status

- `imported-only`

## Source

- Repository: <https://huggingface.co/wizdroid/comfyui-workflows>
- Workflow file: <https://huggingface.co/wizdroid/comfyui-workflows/raw/main/seedvr2-i2i.json>
- Original publisher: `wizdroid`
- Date imported: `2026-08-31`

## Developer notes

- This came from the same workflow pack that also ships Flux2-Klein, Z-Image-Turbo, and MiniMax H3 templates.
- The source README positions this as one of the stronger local upscaling and restoration paths in the pack.

## Our notes

- This looks like a real SeedVR2 workflow to keep, not just a benchmark artifact.
- On an `RTX 3070` with `8 GB` VRAM, expect it to feel tight to heavy, especially if you try to push larger inputs or aggressive tiling.
- Best use case is detail recovery and restoration where quality matters more than speed.

## Required custom nodes

- `ComfyUI-SeedVR2_VideoUpscaler` (`ainvfx`)

## Required model files

- `seedvr2_ema_7b_sharp_fp16.safetensors`
- `ema_vae_fp16.safetensors`

## Notes

- Good candidate when SeedVR2 is the right tool and you want a ready-made ComfyUI path instead of wiring the graph by hand.
