ComfyUI VFX Nodes
by FugitiveExpert01
A growing collection of custom ComfyUI nodes built for VFX production pipelines — designed around the real demands of working with high-resolution imagery, video sequences, and AI-assisted visual effects workflows.
📌 Overview
This repo fills the gaps between off-the-shelf ComfyUI nodes and the specific needs of VFX work: large format images, temporal consistency across video frames, precise spatial control, and clean integration with diffusion-based upscaling and enhancement models.
Nodes are built with video batch support as a first-class concern — not an afterthought.
🧩 Nodes
🔲 TileSplit
Splits an image or video batch into an overlapping grid of tiles, ready to be passed individually to a model.
| Parameter | Type | Description |
|---|---|---|
image |
IMAGE | Input image or video batch |
tiles_x |
INT | Number of columns |
tiles_y |
INT | Number of rows |
overlap_percent |
FLOAT | Overlap between adjacent tiles |
Outputs: tiles (LIST) · debug_image · tile_calc
Features:
- Overlap calculated automatically and stored for seamless reconstruction
- Outputs tiles as
(F, H, W, C)tensors — compatible with video model K-samplers - Debug image showing tile boundaries and overlap regions
- Tile dimensions snapped to multiples of 8 for model compatibility
🔳 TileMerge
Reconstructs a full image or video sequence from processed tiles using Laplacian Pyramid blending for seamless, artifact-free joins.
| Parameter | Type | Description |
|---|---|---|
tiles |
IMAGE (LIST) | Processed tile sequences |
tile_calc |
TILE_CALC | Layout data from TileSplit |
Outputs: image
Features:
- Gaussian feathering masks at overlap regions
- Laplacian frequency blending for natural-looking seams
- Robust handling of tensor shapes returned by video models
- Weighted accumulation handles overlapping regions correctly
⚙️ Installation
1. Clone into your ComfyUI custom nodes folder:
cd ComfyUI/custom_nodes
git clone https://github.com/FugitiveExpert01/ComfyUI-FEnodes.git
2. Restart ComfyUI.
Nodes will appear in the node menu. No additional dependencies beyond what ComfyUI already requires (PyTorch, NumPy, Pillow).
🎬 Typical Workflow
Load Video → TileSplit → [Video Model / K-Sampler per tile] → TileMerge → Save Video
TileSplit outputs a list of tile sequences so each tile can be routed through a video model independently, then TileMerge reconstructs the full frame. This allows processing of resolutions that would otherwise exceed VRAM limits.
🗺️ Roadmap
This repo is actively developed alongside VFX production work.
| Node | Description | Status |
|---|---|---|
| TileSplit | Grid tile splitting for video batches | ✅ Released |
| TileMerge | Laplacian pyramid tile reconstruction | ✅ Released |

🤝 Contributing
Pull requests are welcome. If you're adding a node, please:
- Keep video batch support (
F, H, W, C) as the primary tensor convention - Add a docstring describing what the node does and its input/output types
- Test with both single images and multi-frame video batches
