ComfyUI_RightEyeDisparity

A simple ComfyUI custom node for generating right eye disparity videos for VR. Generates right eye videos efficiently based on left eye video and depth maps.

Features

• 🎬 Video Batch Processing: Memory-efficient design
• 👁️ Right Eye Only Output: Saves memory by processing only what's needed
• 🔧 High-Quality Disparity Generation: Uses proven algorithms from ComfyStereo
• 📹 Workflow Integration: Works seamlessly with Video Combine and Meta Batch nodes

Installation

1. Clone into ComfyUI custom nodes folder:

cd ComfyUI/custom_nodes
git clone https://github.com/KAVVATARE/ComfyUI_RightEyeDisparity.git

2. Install dependencies:

cd ComfyUI_RightEyeDisparity
pip install -r requirements.txt

Usage

Video Right Eye Disparity Node

Inputs:

• images: Left eye video frames (batch)
• depth_maps: Depth map for each frame
• fill_technique: Occlusion filling technique

Output:

• images: Generated right eye video frames

Key Parameters:

• divergence (0.05-15): Disparity strength. Higher values create stronger 3D effect
• separation (-5-5): Horizontal offset adjustment
• stereo_balance (-0.95-0.95): Left/right disparity balance
• fill_technique: Recommended "Fill - Polylines Soft"

Example Workflow

1. Load Video → Load left eye video
2. MiDaS Depth Map → Generate depth maps
3. Video Right Eye Disparity → Generate right eye video
4. Upscale → Optionally upscale left/right separately
5. Video Combine → Save as video with Meta Batch

Memory Optimization Tips

• Adjust batch size to control memory usage
• direction_aware_depth_blur is disabled for faster processing
• Depth map output is omitted to save memory

Troubleshooting

Out of Memory

• Process with smaller batch sizes
• Reduce resolution and upscale after processing

Unnatural Disparity

• Adjust divergence between 2-5
• Check depth map quality
