LTX Video 2.3 version 1.1 GGUF Image to Video — v1.0

This ComfyUI workflow is for turning an image and a prompt into two videos—one with audio and one without. It is a GGUF workflow for LTX Video 2.3 version 1.1.

Its nodes are wired, visible, and grouped; it uses no set/get nodes or subgraph.

To use it, drag an image into the image nodes, adjust the prompt, and press queue.
