LTX-2

LTX-2, the next-generation multimodal AI foundation model from Lightricks, is a complete AI creative engine built for high-demand production workflows. It directly addresses the need for high-fidelity, controllable, and cost-efficient video and audio generation. By transforming text or still images into coherent, delivery-ready 4K video sequences, LTX-2 empowers studios, developers, enterprises, and independent creators to accelerate their pipelines and unlock new levels of creative freedom.

Key Features

LTX-2 is engineered to move beyond simple demos, providing the precision and performance required for professional content delivery.

• 🎬 Native 4K Output at 48 FPS Achieve professional-grade visual quality with native 4K resolution at 48 frames per second, supporting sequences up to 15 seconds long. This capability ensures your generated assets meet broadcast and cinematic standards, eliminating the need for extensive post-generation upscaling.

• 🎧 Synchronized Audio and Video Generation Unlike models that treat sound as an afterthought, LTX-2 generates visuals and synchronized audio in a single, coherent process. This ensures perfect synchronization of motion, dialogue, ambience, and music, providing a foundation for compelling, high-quality storytelling right out of the box.

• ⚙️ Radical Efficiency and Accessibility LTX-2 is optimized for speed and efficiency, running effectively on high-end consumer-grade GPUs. This democratizes access to world-class AI video generation, making professional creative power accessible at significantly lower operational costs compared to models requiring specialized, high-cost infrastructure.

• 🎨 Advanced Creative Control and Customization Maintain granular control over the final output using text, image, depth, and reference-video inputs. Features like multi-keyframe conditioning, 3D camera logic, and temporal outpainting allow creators to precisely shape pacing, motion, style, and narrative coherence across extended scenes.

• 🔗 Production Workflow Integration Designed for real-world pipelines, LTX-2 offers robust API access and connects directly to industry-standard editing suites, broadcast tools, game engines, and VFX pipelines. This seamless integration ensures AI-generated assets flow effortlessly into existing production environments.

Use Cases

LTX-2’s production-ready capabilities translate directly into significant time and cost savings across various creative domains.

• Post Without the Production: Automate traditionally costly and time-consuming tasks like motion tracking, rotoscoping, and plate replacement. LTX-2 delivers high-fidelity, broadcast-ready composites faster than real-time, allowing VFX teams to preserve detail and consistency while drastically reducing post-production cycles.

• From Concept to Dynamic Cutscene: Transform static concept art, character sketches, or keyframes into dynamic, story-driven motion sequences without requiring a full 3D rendering pipeline. Game developers can rapidly generate in-game loops, trailers, or cinematic sequences, using LoRA fine-tuning to maintain stylistic consistency and brand-specific visual identity.

• Faster, Smarter Pre-Production: Visualize storyboards, camera logic, and complex lighting scenarios instantly. Creative teams can simulate camera moves and pacing before stepping onto a physical set, allowing directors and clients to refine compositions and narrative flow with realistic motion previews, saving substantial time and cost during principal photography.

Unique Advantages

LTX-2 distinguishes itself by combining high-fidelity output with an open, accessible architecture that prioritizes developer control and production reality.

• Built for Real Workflows: LTX-2 isn't just a demo tool; it's designed to connect directly into professional pipelines. Its architecture supports both quick previews and delivery-ready 4K outputs, ensuring utility at every stage of the production process, from ideation to final delivery.

• A Truly Open System: LTX-2 is set to be released later this fall with open weights and training code. This strategic openness empowers researchers, enterprises, and independent creators to fully customize, extend, and innovate upon the foundation model, fostering a powerful ecosystem of specialized tools and applications.

• Holistic Multimodal Coherence: By generating synchronized audio and video simultaneously, LTX-2 overcomes the common limitation of many AI video models where sound is mismatched or generated separately. This single, coherent process is essential for creating believable, immersive content.

• Cost-Efficient Power: The radical efficiency that allows LTX-2 to run on consumer-grade GPUs democratizes high-resolution AI video creation, making it a viable, cost-effective solution for independent creators and smaller studios who cannot invest in massive dedicated server farms.

Conclusion

LTX-2 offers the fidelity, control, and efficiency demanded by modern creative pipelines. By providing an open, high-resolution, and multimodal engine, Lightricks is empowering professional creators to integrate AI seamlessly into their production reality.
