A professional-grade, edge-aware anti-aliasing post-processing node for ComfyUI. This node is specifically designed to eliminate jagged edges (aliasing) in AI-generated videos and images without sacrificing overall texture detail.

Description

AI video generation often suffers from "pixel crawling" or "staircase effects" (aliasing) on high-contrast edges. Traditional blur filters fix this by blurring the entire frame, which results in a loss of sharpness.

Features

Smart Edge Detection: Uses mathematical gradients to find jagged boundaries. Detail Preservation: Keeps faces, textures, and backgrounds sharp while smoothing only the "noisy" edges. Adaptive Blending: Smoothly transitions between the original image and the anti-aliased edges.

Parameters & Usage

Find the node under: CustomPostProcess -> Parameter Type Description Recommended Value strength FLOAT The intensity of the smoothing effect. 0.8 - 1.2 edge_threshold FLOAT Sensitivity of edge detection. Lower = more areas smoothed. 0.10 - 0.20 blur_radius INT The width of the anti-aliasing filter. 1 (Sharper) or 2 (Softer) Ideal Workflow Placement: VAE Decode -> Video Adaptive AA -> Video Combine (VHS)

Pro Tips

For Upscaling: Always place this node after an upscale operation to clean up any pixel interpolation artifacts. For Animation: If you notice "flickering" on thin lines, decrease the edge_threshold to allow the node to cover more subtle edges.
