Configuring LTX 2.3 workflow in ComfyUI
ComfyUI
Demo summary
The creator walks through a custom ComfyUI workflow for LTX 2.3, showing how to add the RG3 Power Lora Loader and an image-to-video adapter to improve lip-syncing.
Step-by-step
- Open the pre-built LTX 2.3 image audio to video template in ComfyUI
- Open the subgraph to access internal nodes
- Replace the basic Load LoRA node with the RG3 Power Lora Loader
- Add the LTX 2.3 384 LoRA to the loader
- Add the image-to-video adapter LoRA to the loader
- Set the strength for the top two LoRAs to 0.5
- Set the strength for the image-to-video adapter LoRA to 1.0
- Replace the stock Save Video node with the Video Helper Suite (VHS) node
Watch out for
- The image-to-video adapter LoRA is required if you want to animate lip-syncing from a static image; without it, the animation often fails to work.
Tips
- Use the RG3 Power Lora Loader to manage multiple LoRAs within a single node instead of the basic loader.
- Maintain the original 384 LoRA from the stock template while adding custom adapters.
