Show HN: Ltx-2 AI – 4K Audio-Video Generation with Creative Control

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 Try it here: https://www.jxp.com/ltx-2 https://www.jxp.com/ltx-2 Would love feedback from the HN community — especially on integration use cases, 4K performance, and creative direction tools.
