Attention developers, creatives, and video generation enthusiasts: There’s a next-gen tool entering stage right, and it’s worth a close-up. Fittingly, that’s exactly what we’re giving it.
Meet LTX Video (LTXV), the generative AI video model created by Lightricks engineers and released as open source to drive access and innovation. It’s an AI tool designed to be an assistant and elevator for creatives. Because there’s so much to cover and share, we’re breaking down LTXV’s story and capabilities under four umbrellas: speed, consistency, problem-solving, and innovation.
The scoop: Accessible, cutting-edge generative AI video creation is here. So without further ado, let’s get into how you can grasp it.
Speed
Developed with direct feedback from LTX Studio users, LTXV provides a new framework for researchers to advance solutions for motion consistency, computational efficiency, and scalability while setting new standards for performance.
The result? Breakthroughs in creation speed.
LTXV has the capability to generate 5 seconds of high-quality video in 4 seconds—every second counts, after all.
Let’s break this down. Running on NVIDIA’s H100 GPUs, LTXV achieves eye-opening real-time processing speeds, generating a 5-second video sequence (121 frames at 768×512 resolution) in just 4 seconds (or less) using 20 diffusion steps.
Optimized for both GPU and TPU systems, LTXV reduces video generation times by more than 90%, putting it among the fastest models for high-quality video output. Creatives, take note: If you’re stressing about generation time, LTXV is here to nip that in the bud. And less time for generation = more time for ideating.
Independent creatives and creative studios alike can tap into LTXV if they’re looking to iterate effectively, get immediate results, and implement feedback right away to create something even better than before. LTXV’s generative AI capabilities are designed for innovation within commonly available configurations. Developers and academics looking to advance AI video can also turn to LTXV as fertile ground for further innovation.
Consistency
You might be thinking, “With all this production speed, there ought to be plenty of glitches and quality failures, right?”
Wrong.
LTXV is designed to maintain precision and visual quality without compromising speed or memory efficiency. Running on bfloat16 precision (which provides nearly the same range as full precision but uses less memory), LTXV efficiently generates high-quality video even on widely available prosumer GPUs, such as the RTX 4090.
If you’re in the weeds of video generation and understand the above, great! If not, what it means is that LTXV is designed to run and create smoothly, and precision isn’t sacrificed for speed. In fact, precision has only been further advanced by LTXV.
Producing extended, high-quality videos with consistency across length offers creators flexibility, control, and a lot more tools + legroom to get creative.
Problem-solving
As previously mentioned, LTXV was developed with direct feedback from LTX Studio users. It provides a new framework for researchers to advance solutions for motion consistency, computational efficiency, and scalability.
It was built, in part, to remove the hurdles to video generation and make for a seamless, iterable model that creatives, academics, and marketers can turn to—whether in a pinch or within an extended time frame.
LTXV will also pave the way for Lightricks to develop better generative AI video products that address the needs of many industries interested in AI’s capabilities, such as advertising and filmmaking.
LTXV’s Diffusion Transformer is also key to LTXV’s problem-solving tools. It’s an architecture that ensures smooth, coherent transitions between frames, eliminating issues like object morphing that have plagued previous generations of video models (we’ve all seen ’em). Diffusion models are especially good at creating high-quality samples, which makes them effective tools for tasks like synthesizing images.
In short, you can bid a much-needed farewell to blobby, wonky transitions and imagery.
Innovation
Lightricks shared LTXV with their open community to engage global academics and developers and enable them to build on and help shape the future of AI video. Talk about a next-level brainstorming sesh.
Released on GitHub and Hugging Face, the model was built using PyTorch XLA and runs smoothly on both GPU and TPU systems.
LTXV is standing on the shoulders of unicorns. It follows in the footsteps of Long AnimateDiff, an open-source animation framework Lightricks released earlier this year. LTXV is designed for extensive customization, allowing developers to fine-tune output and fostering a global community of experimentation and advancement—much like Long AnimateDiff.
LTXV’s and Lightricks’ mission are to put cutting-edge video generation within reach on commonly available configurations. With speed, consistency, and problem-solving in tow, innovation practically fosters itself.
Whether you’re an individual creator or a marketing exec looking to spruce up your video capabilities, LTXV can complement evolving needs and generate work worth being proud of.
It’s the first real-time, open-source AI video generation model, and it’s ready when you are.
Welcome to the future
Scalable long-form video production. Faster processing and rendering times. Quality motion and structure consistency. And plenty of room for innovation. LTXV aims to empower global creativity, and their open-source contributions + model leave no stone unturned.
If you’re a creative—or a team of 200 creatives—looking to dabble in everything this generative AI video model has to offer, now’s your chance to take LTXV for a spin.
