SUMMARY

Best For

Enterprise teams needing on-prem deployment, full model customization & IP protection at zero marginal cost — plus multi-shot scene generation, real-footage editing (EXR/IC-LoRA), and physical-AI/robotics base models
Filmmakers and VFX artists using cloud-based generation tools

Which model is right for me?

  • LTX is best for

    • Enterprise teams that need self-hosted deployment, full model ownership, and LoRA fine-tuning without a subscription-based cloud platform
    • Organizations that need to customize, fine-tune, and integrate video models directly into their own products, workflows, and infrastructure
    • Teams that need a complete production capability stack — Retake, Extend, LipDub, HDR, and native Audio-to-Video in a single model
    • Scaling API usage where native 4K output, cost predictability, and deployment flexibility matter at volume
    Try LTX-2.5 Now
  • Runway is best for

    • Filmmakers and VFX artists who want cloud-based generation with strong camera controls and character consistency tools without managing infrastructure
    • Creative teams producing cinematic video content who don't need on-prem deployment or model customization

LTX-2.5 Model

LTX-2.5 is here. Sharper, faster, yours to build on.

A stronger foundation for the worlds already being built on LTX. Native multishot, precise editing, and 4K HDR output, built to hold up from first draft to final render. Learn More →

Multishot

Generate connected scenes, not single clips. Hold character, environment, lighting, and voice consistent across wide, medium, and close-up shots in one generation.

Auto Duration

Let the model set the pace. Clip length is predicted from the described action, so scenes land at the right duration without manual tuning.

Man diving off rocks into the sea — Auto Duration example

Native HDR

Generate high-resolution HDR footage built for professional finishing. Output drops straight into your grading and color pipeline, ready for the big screen.

Volcano erupting with lava flowing down dark rocky terrain under a dusky sky.

Diffusion Fidelity Rendering

Generate every scene from a grid of high-fidelity keyframes that focus detail where it matters most. Get industry-leading pixel quality that holds up frame by frame, even on a cinema screen.

Customer Voices

"The industry has long needed a bridge between generative AI and professional finishing standards. By moving past 8-bit SDR, we’ve eliminated the technical gap that kept AI assets from being used on high-fidelity displays and within complex spatial experiences. We’re no longer compromising on bit depth; we’re finally getting the dynamic range required for cinematic immersion in XR and virtual production. In the past, AI-generated content was a black box; you couldn't relight it or grade it without the image falling apart. Now, these assets behave like the real world, carrying the dynamic range needed to sit alongside traditionally captured elements. This gives our teams a professional-grade toolkit to integrate generative AI into their creative process."
