Lightricks has released an AI model called LTX Video (LTXV) it says generates five seconds of 768 x 512 resolution video (121 frames) in just four seconds, outputting in less time than it takes to watch. The model can run on consumer-grade hardware and is open source, positioning Lightricks as a mass market challenger to firms like Adobe, OpenAI, Google and their proprietary systems. “It’s time for an open-sourced video model that the global academic and developer community can build on and help shape the future of AI video,” Lightricks co-founder and CEO Zeev Farbman said.

“With real-time processing, scalability for long-form video, and a compact architecture that runs efficiently even on consumer-grade hardware, LTXV is poised to make professional-grade generative video technology accessible to a broader audience — an approach that could disrupt the industry’s status quo,” according to VentureBeat.

Lightricks — the Israeli company behind the previsualization tool LTX Studio and the beautification app Facetune — says it developed the new tool based on feedback from users.

The fact that LTXV can run on widely available prosumer GPUs, such as Nvidia’s RTX 4090, makes it “particularly suited for smaller creative studios and independent creators,” the company explains in a press release.

The two billion parameter LTXV model achieved its four-second, 768 x 512 performance running on Nvidia H100 GPUs. Tom’s Guide reports “it will take a fair bit longer than four seconds” to output five seconds of high-quality video using the RTX 4090, though VentureBeat attests that even on consumer-grade hardware, “LTXV delivers near-real-time performance, making it one of the fastest models of its kind.”

Tom’s concludes that “being able to run a model like this comfortably on a good gaming PC is a huge step up for AI video and gets us to a point where it could be integrated into games or video editing tools for real-time rendering and previews.”

‍“LTXV represents a new era of AI-generated video,” Lightricks co-founder and CTO Yaron Inger said. “By designing a robust video encoding model that compresses the video in a very compact way (1:192 of the original video), we’ve achieved unprecedented speed while improving motion consistency and visual continuity.”

Tom’s says LTXV can be accessed through the new desktop version of ComfyUI (now in closed beta for Windows/macOS/Linux) “if you have a good enough gaming PC.”

VentureBeat reports that Lightricks has also released it on GitHub and Hugging Face in “an initial ‘community preview’ phase to allow for testing and feedback.” The model is available under an OpenRAIL license, “ensuring that derivatives remain open for academic and commercial use,” VB notes.
