LTX-2.5 vs HunyuanVideo 1.5

LTX is the enterprise video standard for 2026: native 4K, audio-to-video, on-prem deployment, and a production API at $0.04/sec. HunyuanVideo 1.5 tops out at 720p and lacks the speed and infrastructure readiness production teams require.

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
Developers running open-source video generation on consumer GPUs

Which model is right for me?

  • LTX is best for

    • Production teams whose deliverables go to broadcast, commercial review, or any screen where resolution and frame rate are non-negotiable
    • Teams that need controls beyond raw generation — Retake, Extend, LipDub, and native Audio-to-Video built in, not bolted on from separate tools
    • Building scenes with structure and length — up to 20 seconds per clip, full motion control, and character consistency via LoRA
    • Deploying at scale where generation speed, cost per second, and 4K output all have to work together
    Try LTX-2.5 Now
  • HunyuanVideo 1.5 is best for

    • Developers running open-source video generation on consumer GPUs without enterprise infrastructure requirements
    • Researchers experimenting with text-to-video and image-to-video generation without needing production-grade infrastructure

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.

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.

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."
