Lightricks, a company involved in developing AI tools for content creation, has announced the release of its latest video model, LTXV-13B.
As the name suggests, the new model boasts 13 billion parameters to improve the quality of the creator’s video, even when running on consumer-grade hardware.
This is the first version of LTXV that offers a new “multi-scale rendering” technology that allows for a faster, more realistic approach to scene generation, in addition to “sampling” controls that improve video quality. It is also the first Lightricks model trained with high quality visual content provided by Shutterstock and Getty, and is licensed through partnerships with companies.
13B is integrated into Lightricks’ AI storyboarding and video creation web app LTX Studio, and is open source and free to use via GitHub and Hugging Face.
Accelerating open source video AI
The release of the LTXV-13B is built from a video generation model with 2 billion parameters. When LTX Video debuted in November, it was one of the first open source models of its kind, challenging its own AI video generation model makers such as Openai, Google, and Adobe.
The release of LTXV under the open source model, combined with its compact architecture, has proven to be a game changer. It claimed to be efficient enough to run on consumer graphics cards like the Nvidia RTX 4090, and provides the visual fidelity and consistency of movement of professional grade tools. LTXV was called the first AI model to generate video faster than EWEEK than real-time.
LTXV has emerged as a favorite for marketing teams and content creators after being pressured to put AI video generation into the hands of a much wider audience and create high-quality video assets.
The LTXV-13B improves video quality and adds new features that are easy for end-users to access. It can run as fast as its predecessors and on consumer hardware.
Enhanced scene rendering
One of the most interesting new features in the LTXV-13B is multi-scale rendering. This allows users to replicate the stage scene construction process that is normally used in Hollywood productions. AI starts with a basic layout and adds detail and clarity to each frame. During the process, it gradually improves the resolution and improves the details.
According to Lightricks, this technique offers two major advantages: Improved realism and reduced delay. The rendering speed is up to 30 times faster than competing video generation models, the company says.
The LTXV-13B is enhanced by many new open source contributions, including upsampling controls to reduce the impact of noise on all frames and improve granularity, such as VACE model inference tools that support reference-to-video editing. It also uses the Uefficive Q8 kernel to scale performance on low power devices such as laptops.
The open source version of the LTXV-13B is available on GitHub and Hugging Face, but the easiest way for non-technical users to access the model is through LTX Studio.
LTX Studio is used by marketing teams, advertising studios and other content creators to turn ideas into storyboards, pitch decks and ultimately sophisticated videos without the hassle of traditional studio-based productions. Teams can start a project by uploading scripts, basic technical prompts, reference images, or sketch-to-shot workflows. Users start with rough sketches and quickly iterate by adding the generated details to the AI.
By eliminating the need for full-scale production teams, location shoots, physical studios and traditional storyboards, LTX Studio offers marketing teams benefits, giving them time to explore more ideas and accelerate video creation. LTX Studio recently won the Digiday Award for Best Advertising Innovation of 2024.
Multi-model app
The LTXV-13B is not the only model available on the platform. Last month, Lightricks announced that Google’s video model Veo 2 will be integrating its app. Support for the popular flux model was added in November, allowing users to generate reference stills.
Users can switch between multiple models for each project and compare outputs. More models are available in LTX Studio, with several specialized editing tools including keyframe editing, camera motion control, character and scene level motion adjustment, multi-shot sequencing, and editing. This platform allows users to narrow down their video production beyond what is possible with the standalone LTXV-13B model.
Zeev Farbman, co-founder and CEO of Lightricks, says the launch of the LTXV-13B is a pivotal moment for the early AI video generation industry. “Our users are now able to create content with more consistency, better quality and more stringent control,” he said in a statement.
