ComfyUI SS Before After Node

[](LICENSE)

[]()

Create stunning before-and-after transition videos directly in ComfyUI.

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.

✨ Features

  • 🔄 SSBeforeAndAfterVideo – Create videos with fade and wipe transitions between two images.
  • 🌌 Depth Map Support – Create depth-aware transitions (SSBeforeAndAfterVideoWithDepthMap) for immersive effects.
  • 🎬 Customizable Output – High-quality output with custom resolution, fps, feathering, and looping.
  • ⚡ FFmpeg Integration – Robust video encoding.
  • 📊 Progress Tracking – Built-in progress bar for frame generation.

    • 🚀 Quick Start

    Prerequisites

  • ComfyUI installed
  • FFmpeg installed and available in system PATH

    • Installation

  • Go to your ComfyUI custom nodes directory:

    • “`bash

    cd ComfyUI/custom_nodes

    “`

  • Clone this repository:

    • “`bash

    git clone https://github.com/SamSeenX/ComfyUI_SSBeforeAfterNode.git

    “`

  • Install dependencies:

    • “`bash

    pip install -r ComfyUI_SSBeforeAfterNode/requirements.txt

    “`

  • Restart ComfyUI.

    • Basic Usage

  • Add the node SSBeforeAndAfterVideo or SSBeforeAndAfterVideoWithDepthMap to your workflow.
  • Connect your before_image and after_image inputs.
  • Configure parameters (transition type, duration, FPS).
  • Run the workflow.

    • 📖 Documentation

    Node 1: SSBeforeAndAfterVideo

    Creates before-and-after transition videos using classic fade and wipe effects.

    Parameters:

  • transition_type: fade, wipe_from_left, wipe_from_top, etc.
  • transition_duration: 0.5 – 10.0 seconds.
  • feather: Softness of the wipe edge (0.0 – 1.0).

    • Node 2: SSBeforeAndAfterVideoWithDepthMap

    Creates transitions using a depth map, revealing images based on depth (e.g., back-to-front).

    Parameters:

  • depth_map: Input depth map image.
  • transition_type: back_to_front, front_to_back, middle_out.
  • easing_method: Smoothness of the transition.
