What it does
LTX-Video is a video-generation model from Lightricks. Describe a scene or give it a picture and it creates a video; it can also extend clips and animate between keyframes. It works with ComfyUI, a visual tool for AI workflows.
The README says development has moved to LTX-2, a newer model that also creates matching sound.
Who it's for
Video creators, artists and developers who want to generate video with AI.
