Frequently Asked Questions About LTX-2 AI

Everything you need to know about the LTX-2 video generation model

Is LTX-2 open-source? Can I run it locally?

Yes! LTX-2 is released under the Apache 2.0 license, making it fully open-source. You can download the model weights and run it locally on your own hardware, deploy it on cloud infrastructure, or integrate it into your applications. This gives you complete control over your video generation pipeline without vendor lock-in.

What is the maximum resolution and duration for LTX-2 videos?

LTX-2 supports video generation up to 4K resolution with frame rates up to 50 FPS. Video duration ranges from 6 to 20 seconds per generation. For longer content, you can generate multiple clips and combine them, or use our API for programmatic batch generation.

Does LTX-2 really generate audio with the video?

Yes, native audio synchronization is one of LTX-2's breakthrough features. The model generates synchronized audio including dialogue, environmental sounds, and background music that matches the visual content perfectly. This eliminates the need for separate audio tools or manual lip-sync corrections.

How does LTX-2 compare to Sora and Runway?

Unlike Sora and Runway which are closed-source, cloud-only services, LTX-2 is fully open-source and can be self-hosted. It's the only major model offering native audio synchronization. While others typically offer 1080p at 24-30 FPS, LTX-2 delivers up to 4K at 50 FPS. Plus, you can fine-tune LTX-2 with LoRA adapters for specialized applications.
