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. Native Batch Support: Optimized for video workflows and large image batches.

🛠 Installation Navigate to your ComfyUI directory: ComfyUI/custom_nodes/. Create a new folder named MyCustomAA. Place the video_aa_node.py and __init__.py files into that folder. Restart ComfyUI.

🚀 Parameters & Usage Find the node under: CustomPostProcess -> 🚀 Video Adaptive Anti-Aliasing 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.
