Synchronized Audio and Video Generation
LTX-2 unifies sound and motion, producing synchronized dialogue, ambient sound, and music directly within the same generation pass. Every beat, expression, and motion stays in sync for natural, cinematic storytelling.
| Prompt | Generated Video |
|---|---|
A cinematic street performance at sunset. The musician strums a guitar and sings softly as pedestrians pass by. The camera tracks smoothly, capturing synchronized lip movement, ambient city sounds, and gentle music. Every frame feels alive, with natural audio-video harmony and emotional realism. |
Native 4K Fidelity at Real-Time Performance
LTX-2 delivers native 4K video at up to 50 fps, combining sharp textures, balanced lighting, and physically accurate motion. It achieves real-time rendering on multi-GPU setups while maintaining cinematic clarity and speed.
| Prompt | Generated Video |
|---|---|
A 3D drone-style camera follows a skateboarder performing tricks through an urban tunnel. Sparks from the board reflect off the wet walls as the camera rotates and tilts, keeping perfect motion flow and focus. |
creative-control
LTX-2 supports multi-keyframe input, 3D camera path logic, and LoRA fine-tuning, allowing creators to control motion, timing, and scene composition with frame-level accuracy. This gives directors cinematic flexibility while maintaining consistency across sequences.
| Prompt | Generated Video |
|---|---|
A single continuous 3D camera orbit around a dancer performing in an empty theater. The camera follows a smooth arc path, maintaining focus on her fluid movements and controlled lighting transitions, creating a sense of cinematic depth. |
Efficient and Scalable Performance
Powered by a hybrid diffusion-transformer architecture, LTX-2 runs efficiently on consumer GPUs while scaling across multi-GPU clusters.
Open-Source and Developer-Friendly
LTX-2 is fully open source. Developers can explore the architecture, fine-tune weights, or integrate the model with editing suites, VFX pipelines, or game engines. Its openness invites experimentation and builds a broader creative ecosystem.
LTX-2 vs Other Models
LTX-2 leads with synchronized audio-video generation, native 4K fidelity, real-time performance, and open-source flexibility. Compared to closed systems, it offers deeper creative control, faster iteration, and a transparent development ecosystem.
