OVERVIEW

What is LTX?

LTX is lightricks' first-party open video model and production platform for controllable, synchronized audio-video generation. It sits in the Video Creation category and is designed around video concepting, generation, localization, and post-production. Its main capabilities include joint video and audio generation, open model weights, long-form creative controls.

The product is especially relevant for production workflows, local experimentation, audio-led video. In practice, LTX can help users produce or iterate on video without starting every shot from a traditional editing timeline. It works best as part of a reviewed workflow: start with a clear goal, provide useful context, assess the output, and refine it before relying on the result.

CORE FEATURES

What LTX can do

01

Joint video and audio generation

Joint video and audio generation is central to the LTX workflow, helping users begin with less setup and reach a workable first result faster.

02

Open model weights

This capability makes LTX more useful for local experimentation, especially when several iterations are needed.

03

Long-form creative controls

LTX combines this with joint video and audio generation, so the output can remain connected to the wider task instead of becoming an isolated feature.

USE CASES

Where it fits best

Production workflows

Use LTX for production workflows when you want to produce or iterate on video without starting every shot from a traditional editing timeline. Review the result against the original brief before sharing or publishing it.

Local experimentation

Use LTX for local experimentation when you want to apply open model weights to a practical workflow. Review the result against the original brief before sharing or publishing it.

Audio-led video

Use LTX for audio-led video when you want to apply long-form creative controls to a practical workflow. Review the result against the original brief before sharing or publishing it.

BEST FOR
