Most AI video tools hand you a black box: closed weights, a subscription, and no way to see what is happening under the hood. LTX takes the opposite approach. Built by Lightricks, LTX is an open foundation model that generates and simulates across video, audio, and the physical world, and it puts the weights, the code, and the control in your hands.
At the center of the model is LTX-2.3, a 22B-parameter dual-stream diffusion transformer that produces native 4K video at up to 50 frames per second, with audio and video generated together in a single pass rather than stitched together afterward. Artificial Analysis, an independent benchmarking group, currently ranks LTX among the top three AI video models in the world.
You choose how you want to use it. Download the open weights and run LTX-2.3 on your own hardware. License the model for on-premise deployment backed by enterprise support. Or build directly on LTX Studio, the production suite that turns the model into a full creative workflow. Companies like ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already rely on LTX for their own work.
LTX is not built for one-off social clips. It is infrastructure for teams that generate motion, audio, and physical environments as part of their own products and pipelines.

Act-Two
Act-Two allows for the animation of any character by capturing and transferring movements, facial expressions, and dialogue from a performance video onto a static image or reference video of the character. To utilize this feature, you can choose the Gen‑4 Video model and click on the Act‑Two icon within Runway’s online interface, where you will need to provide two key inputs: a video showcasing an actor performing the desired scene and a character input, which can either be an image or a video clip. Additionally, you have the option to enable gesture control to effectively map the actor's hand and body movements onto the character images. Act-Two automatically integrates environmental and camera movements into static images, accommodates various angles, non-human subjects, and different artistic styles, while preserving the original dynamics of the scene when using character videos, although it focuses on facial gestures instead of full-body movement. Users are given the flexibility to fine-tune facial expressiveness on a scale, allowing them to strike a balance between natural motion and character consistency. Furthermore, they can preview results in real time and produce high-definition clips that last up to 30 seconds, making it a versatile tool for animators. This innovative approach enhances the creative possibilities for animators and filmmakers alike.
