## What it is
Official repository for LTX-Video, a DiT-based open-weights video generation model from Lightricks that generates high-fidelity video (up to 4K, 50 FPS) from text, image, or audio inputs with synchronized audio. It provides inference code, ComfyUI and Diffusers integrations, and links to training tools, with development continuing in the LTX-2 repository.

## Use cases
- generate videos from text prompts
- animate a still image into a video
- generate video with synchronized audio
- run video generation locally on my own GPU
- integrate video generation into ComfyUI workflows
- use a video generation model with Hugging Face diffusers
- fine-tune a video model on my own footage

## When to choose
- you need open-weights video generation you can run or fine-tune yourself
- you want synchronized audio+video output in one model
- you need ComfyUI or Diffusers integration for video generation
- you want high-resolution (up to 4K) video generation with multiple performance modes

## When to avoid
- you only need a hosted API without managing GPUs (use the LTX API instead)
- you need lightweight video editing rather than generative video creation
- you lack a capable GPU and cannot use cloud inference
- you need a closed-source commercial product with support guarantees
