What is LTX-2 API?

The LTX-2 API is a professional-grade AI video generation platform that enables developers to create stunning videos from text prompts or static images. Built on the cutting-edge LTX-2 model from Lightricks, our API delivers enterprise-quality video generation through a simple RESTful interface.

Whether you're building a content creation platform, automating marketing video production, or developing the next generation of AI-powered tools, the LTX-2 API provides the capabilities you need. Our platform supports both Text-to-Video (T2V) generation for creating videos from natural language descriptions, and Image-to-Video (I2V) transformation for animating static images into dynamic video content.

With support for resolutions up to 4K, frame rates of 25 or 50 FPS, and video durations from 6 to 20 seconds, the LTX-2 API covers a wide range of professional video production needs. Choose between Fast mode for rapid prototyping or Pro mode for maximum quality output.

Frequently Asked Questions

What is the maximum video resolution supported by LTX-2 API?

LTX-2 API supports video generation up to 4K (3840x2160) resolution. You can also choose 1080p (Full HD) or 1440p (2K) depending on your needs. Higher resolutions consume more credits per second of generated video.

Does LTX-2 API support asynchronous video generation?

Yes, LTX-2 API uses an asynchronous task-based architecture. When you submit a generation request, you receive a task_id immediately. You can poll the status endpoint or configure webhooks to receive notifications when generation completes.

What's the difference between Text-to-Video and Image-to-Video?

Text-to-Video (T2V) generates videos entirely from text descriptions, while Image-to-Video (I2V) uses a static image as the starting frame and animates it. I2V is ideal when you have existing visual assets you want to bring to life.

How long are generated videos stored?

Generated videos are stored on our servers for 24 hours after creation. During this time, you can download the video multiple times using the provided URL. After 24 hours, videos are automatically deleted.
