# ComfyUI-LTXVideo
ComfyUI-LTXVideo is a collection of custom nodes for ComfyUI designed to integrate the LTXVideo diffusion model. These nodes enable workflows for text-to-video, image-to-video, and video-to-video generation. The main LTXVideo repository can be found [here](https://github.com/Lightricks/LTX-Video).

## Installation

Installation via [ComfyUI-Manager](https://github.com/ltdrdata/ComfyUI-Manager) is preferred. Simply search for `ComfyUI-LTXVideo` in the list of nodes and follow installation instructions.

### Manual installation

1. Install ComfyUI
2. Clone this repository to `custom-nodes` folder in your ComfyUI installation directory.
3. Install the required packages:
```bash
cd custom_nodes/ComfyUI-LTXVideo && pip install -r requirements.txt
```
For portable ComfyUI installations, run
```
.\python_embeded\python.exe -m pip install -r .\ComfyUI\custom_nodes\ComfyUI-LTXVideo\requirements.txt
```

### Models

1. Download [ltx-video-2b-v0.9.safetensors](https://huggingface.co/Lightricks/LTX-Video/blob/main/ltx-video-2b-v0.9.safetensors) from Hugging Face and place it under `models/checkpoints`.
2. [Install git-lfs](https://docs.github.com/en/repositories/working-with-files/managing-large-files/installing-git-large-file-storage) and clone the text encoder model to `models/text_encoders`:
```bash
cd models/text_encoders && git clone https://huggingface.co/PixArt-alpha/PixArt-XL-2-1024-MS
```
