I built Ltx-2 AI, a next-generation video generation model that unifies sound, motion, and visual storytelling in one pass. Unlike fragmented workflows that require separate dubbing, rendering, and editing, Ltx-2 AI delivers synchronized audio-visual output — precise, cinematic, and production-ready.

What it does:

Generates synchronized audio + video in a single pass

Delivers native 4K textures and frame-consistent motion

Offers multi-mode performance — fast preview to high-fidelity render

Supports multi-keyframe control, 3D camera logic, and LoRA style adapters

Accepts text, image, clip, depth, and audio inputs

Provides open APIs and SDKs for integration and automation

Who it’s for:

Filmmakers, marketers, and animation studios

Game and XR developers

Post-production and pre-vis teams

Anyone needing cinematic motion without full 3D pipelines

Would love feedback from the HN community — especially on integration use cases, 4K performance, and creative direction tools.
