<h1 id="comfyui-ss-before-after-node-l91bf4tue">ComfyUI SS Before After Node</h1>This repository provides two powerful custom nodes for ComfyUI to create stunning before-and-after transition videos. These nodes are designed for visual comparisons, transformations, and creative effects, supporting both standard and depth map-based transitions.<h2 id="features-ihdw3vthv">Features</h2><ul><li>SSBeforeAndAfterVideo: Create videos with fade and wipe transitions between two images.</li><li>SSBeforeAndAfterVideoWithDepthMap: Create depth-aware transitions using a depth map for more immersive effects.</li><li>High-quality output with customizable resolution, frame rate, feathering, and looping.</li><li>Automatic handling of output directories and filenames.</li><li>Progress bar for frame generation.</li><li>Robust ffmpeg integration for video encoding.</li></ul><a target="_blank" rel="ugc" href="https://github.com/MrSamSeen/ComfyUI_SSBeforeAfterNode">https://github.com/MrSamSeen/ComfyUI_SSBeforeAfterNode</a><hr /><h2 id="node-1:-ssbeforeandaftervideo-d35prhgs2">Node 1: SSBeforeAndAfterVideo</h2><h3 id="description-h7xpwnoxo">Description</h3>Creates before-and-after transition videos using classic fade and wipe effects.
