Adds a batch variant that keeps one ffmpeg writer alive across requeued runs via meta_batch.outputs, so long videos stream to disk instead of accumulating frames in RAM. Fixes the 48-byte truncated mp4 left behind by an interrupted batch.
ComfyUI-DukeStereo
A ComfyUI custom node that converts video frames to side-by-side (SBS) stereo format for VR viewing.
Features
- Polylines Fill - High-quality gap filling during stereo warping (from StereoImage Node)
- Edge-aware depth blur - Smooths depth while preserving edges
- Streaming output - RAM-efficient, writes frames directly to video
- H.264/yuv420p - VR-player compatible output
- Format-Strings -
%date:yyyy-MM-dd%,%time:HH-mm-ss%,%divergence%,%width%etc. - Home-Expansion -
~/video/...paths supported - Auto-Increment - Existing files get
_001,_002suffix
Installation
cd ComfyUI/custom_nodes
git clone https://github.com/killertofu86/ComfyUI-DukeStereo.git
pip install -r ComfyUI-DukeStereo/requirements.txt
Requirements
- torch, transformers, numpy, Pillow, numba, scipy, ffmpeg
Parameters
| Parameter | Default | Description |
|---|---|---|
| output_path | stereo_output.mp4 | Output path with format strings |
| divergence | 2.5 | 3D strength (higher = more depth) |
| separation | 0.0 | Additional horizontal offset |
| stereo_offset_exponent | 2.0 | Non-linear depth curve |
| convergence_point | 1.0 | Zero-parallax plane (0.0-1.0) |
| fill_technique | polylines_soft | Gap filling: polylines_soft, polylines_sharp, none |
| depth_blur | 0 | Depth blur kernel (0 = off) |
| depth_blur_edge_threshold | 6.0 | Edge preservation threshold |
| fps | 24 | Output framerate |
| crf | 19 | Quality (lower = better) |
Inputs
- images - Video frames (IMAGE)
- depth_maps - Depth maps from LeReS or similar (IMAGE)
