# ComfyUI-Lightx2vWrapper
|
|
|
|
ComfyUI custom nodes for [LightX2V](https://github.com/ModelTC/LightX2V). The
|
|
wrapper exposes LightX2V's modular configuration and runner APIs, together
|
|
with ComfyUI-friendly file inputs and output previews.

## Supported workflows
|
|
|
|
The repository includes runnable workflow examples under
|
|
[`example_workflows/`](example_workflows/):
|
|
|
|
- [Wan 2.2](example_workflows/lighx2v_wan2.2.json) text/image-to-video
|
|
- [SekoTalk](example_workflows/lightx2v_seko_talk.json) and [static
|
|
SekoTalk](example_workflows/lightx2v_seko_talk_static.json)
|
|
- [Multi-person SekoTalk](example_workflows/lightx2v_seko_talk_multi_talk.json)
|
|
- [SeedVR2](example_workflows/lightx2v_seedvr.json) video restoration
|
|
- [SwiftVR image](example_workflows/lightx2v_swiftvr_image.json) and [SwiftVR
|
|
video](example_workflows/lightx2v_swiftvr_video.json) restoration
|
|
|
|
The examples are versioned with the wrapper and are the best reference for
|
|
current node names and connections.
|
|
|
|
## Installation
|
|
|
|
Clone the repository with its LightX2V submodule into ComfyUI's
|
|
`custom_nodes` directory:
|
|
|
|
```bash
|
|
cd ComfyUI/custom_nodes
|
|
git clone --recursive https://github.com/ModelTC/ComfyUI-Lightx2vWrapper.git
|
|
cd ComfyUI-Lightx2vWrapper
|
|
python -m pip install -r lightx2v/requirements.txt
|
|
python -m pip install -r requirements.txt
|
|
```
|
|
|
|
For an existing checkout, update the submodule with:
|
|
|
|
```bash
|
|
git submodule update --init --recursive
|
|
```
|
|
|
|
Download the model files from [LightX2V on Hugging Face](https://huggingface.co/lightx2v)
|
|
and place them under `ComfyUI/models/lightx2v/`.
|
|
|
|
## Node groups
|
|
|
|
- **Configuration:** `LightX2VInferenceConfig`, `LightX2VTeaCache`,
|
|
`LightX2VQuantization`, and `LightX2VMemoryOptimization`.
|
|
- **Composition:** `LightX2VConfigCombinerV2` and `LightX2VConfigCombinerV3`.
|
|
- **Inference:** `LightX2VModularInferenceV2`.
|
|
- **Talk inputs:** single-object, file-list, JSON, and multi-object talk
|
|
combiners.
|
|
- **Video inputs and restoration:** `LightX2VInputVideoPath`, SeedVR2 and
|
|
SwiftVR loaders/samplers, plus `LightX2VOutputVideoPreview`.
|
|
- **LoRA:** `LightX2VLoRALoader`.
|
|
|
|
The inference node currently accepts the model classes exposed by
|
|
`model_utils.support_model_cls_list`: Wan 2.1/2.2 variants, SekoTalk,
|
|
Qwen Image, and SeedVR2. The retired `*_distill` values remain selectable as
|
|
compatibility aliases for saved ComfyUI workflows and are normalized before
|
|
LightX2V's runner is built.
|
|
|
|
## Model files
|
|
|
|
Place each model in its own directory under `ComfyUI/models/lightx2v/`. LoRA
|
|
files can be placed in either `ComfyUI/models/lightx2v/loras/` or
|
|
`ComfyUI/models/loras/`.
|
|
|
|
```text
|
|
ComfyUI/models/lightx2v/
|
|
├── Wan2.2-I2V-A14B-distill-fp8/
|
|
├── seedvr2_ema_3b_fp8/
|
|
└── loras/
|
|
```
|
|
|
|
The exact directory names depend on the downloaded checkpoint. The model
|
|
picker only lists directories that exist on the local ComfyUI installation.
|
|
|
|
## Development
|
|
|
|
Install the development hook and run the same checks used by CI:
|
|
|
|
```bash
|
|
python -m pip install pre-commit
|
|
pre-commit install
|
|
pre-commit run --all-files
|
|
```
