How to Run LTX in ComfyUI for Image to Video Generation
Installation Guide
Custom Nodes
If there are red nodes in the workflow, it means the workflow lacks certain required nodes. Install the custom nodes for the workflow to work:
- Go to ComfyUI Manager > Click Install Missing Custom Nodes
- Check the list of custom nodes that need to be installed and click install
Is Your Custom Nodes List Empty?
If your list of missing custom nodes is empty, you might already have LTX installed but an older version:
- Go to Custom Nodes Manager
- Search for LTX in the list and Update ComfyUI-LTXVideo
- Click Restart and Click Refresh to refresh Node Definition in workspace
- Open the workflow again and your issue should be resolved
Models
For this guide you'll need 4 models. 2 will be auto-downloaded and 2 will have to be downloaded manually:
- Go to ComfyUI Manager > Click Model Manager
- When you find the exact model you're looking for, click install and press refresh when finished
Model Path Source
Use the model path source if you prefer to install the models using model's link address and paste into ThinkDiffusion MyFiles using upload URL.
Step-by-Step Workflow Guide
The LTX workflow in ComfyUI provides a streamlined approach to image-to-video generation. The process involves:
- Loading your source image
- Configuring LTX model parameters
- Setting generation parameters (resolution, frame count, FPS)
- Running the generation process
- Exporting the final video
Examples
LTX excels at various image-to-video scenarios:
