# LTX-Video

[LTX-Video](https://huggingface.co/Lightricks/LTX-Video) is a very efficient video model by lightricks. The important thing with this model is to give it long descriptive prompts.

<Tip>
  Make sure your ComfyUI is updated.

  * [Download ComfyUI](https://www.comfy.org/download)
  * [Update Guide](/installation/update_comfyui)

  Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
  If you can't find them in the template, your ComfyUI may be outdated.(Desktop version's update will delay sometime)

  If nodes are missing when loading a workflow, possible reasons:

  1. Not using the latest ComfyUI version(Nightly version)
  2. Using Stable or Desktop version (Latest changes may not be included)
  3. Some nodes failed to import at startup
</Tip>

## Multi Frame Control

You can download the input images: [starting frame](https://raw.githubusercontent.com/Comfy-Org/example_workflows/refs/heads/main/ltxv/multi-frame/house1.png) and [ending frame](https://raw.githubusercontent.com/Comfy-Org/example_workflows/refs/heads/main/ltxv/multi-frame/house2.png).
