ComfyUI WanVideo Auto Resize

A high-performance ComfyUI custom node for intelligent image resizing with industry-standard presets and smart orientation detection. Optimized for video workflows and batch processing.

Features

  • Industry Standard Presets: 480p, 576p, 720p, 1080p resolutions
  • Smart Orientation Detection: Automatic portrait/landscape/square detection with improved ranges
  • Multiple Resize Modes: Keep Proportion, Pad, Crop, Stretch
  • Quality Options: Multiple interpolation methods for different use cases
  • GPU Accelerated: CUDA optimized with automatic mixed precision
  • Flexible Padding: Black, White, Gray, or Blur edge options

Installation

  1. Clone into your ComfyUI custom_nodes directory:

    cd ComfyUI/custom_nodes
git clone https://github.com/your-username/ComfyUI-WanVideoAutoResize

  2. Restart ComfyUI

Usage

Input Parameters

  • Preset Resolution: Choose from standard resolutions or Custom
  • Resize Mode: How to handle aspect ratio differences
  • Orientation Priority: Auto-detect or force specific orientation
  • Interpolation: Choose quality vs speed
    • Bilinear: Good balance of speed and quality (default)
    • Bicubic: Higher quality, slower processing
    • Nearest: Maximum speed, good for pixel art
    • Lanczos: High-quality downscaling

Outputs

  • image: Processed image tensor
  • width/height: Final dimensions
  • orientation: Detected orientation
  • aspect_ratio: Final aspect ratio
  • resize_info: Processing details

Orientation Detection

Improved range detection handles near-square images better:

  • Square: Aspect ratio 0.85-1.18 (e.g., 410×390 = 1.05)
  • Landscape: Aspect ratio > 1.18
  • Portrait: Aspect ratio < 0.85

Performance

  • GPU Optimization: Automatic CUDA acceleration when available
  • Memory Efficient: Smart memory management for large images
  • Fast Interpolation: Nearest neighbor for maximum speed
  • Quality Interpolation: Bicubic and Lanczos for best results
