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 that the workflow lacks the certain required nodes. Install the custom nodes in order for the workflow to work.
- Go to ComfyUI Manager > Click Install Missing Custom Nodes
- Check the list below if there's a list of custom nodes that needs to be installed and click the 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.
