Source description

Personal upscaler. With the default settings, 720p images (realistic) with a good amount of detail work best. For anime and other content, lower settings may suffice. However, you are free to change the parameters.

Adjust the First Stage Denoise and Second Stage Denoise nodes to control how much the model re-imagines details. Higher values add more detail but can alter the image more. A good range is 0.4-0.7.

Purpose

  • Ultra Upscaler is a personal image-upscaling workflow: it takes an image and produces an upscaled image, with realistic 720p images that have good detail described as the best fit with default settings.

Flow

  • The First Stage Denoise and Second Stage Denoise nodes control how much detail the model re-imagines.

Inputs and outputs

  • For anime and other content, lower settings may suffice.

Setup

  • The base model is SDXL 1.0.

Dependencies

  • Listed model files: bbox/face_yolov8m.pt, controlnet-tile-sdxl-1.0.safetensors, epicrealismXL_vxviiCrystalclear.safetensors, and sdxl_lightning_8step_lora.safetensors.

  • Named ComfyUI node packs: comfyui_essentials, comfyui-impact-pack, comfyui-impact-subpack, comfyui-kjnodes, and comfyui-wd14-tagger.

Configuration

  • The described denoise range is 0.4–0.7; higher values add detail but can alter the image more.
