JXP LTX 2.3 AI Video Generator

JXP LTX 2.3 is an AI video generator aimed at producing high-fidelity cinematic clips with matched audio. It can turn text prompts, images or audio into videos, and offers both in-browser generation and options for local workflows.

The system uses a multimodal audio‑visual transformer to process text, images, audio and video together, so motion, visuals and sound stay in sync. This release emphasises clearer audio, improved prompt understanding, better image-to-video motion and native portrait output.

• Text-to-video and image-to-video generation from prompts or reference images
• Audio-to-video generation using voice, music or sound effects to influence motion and pacing
• Native 4K output at 50 fps and support for 20-second clips
• Portrait (vertical) video support for social formats
• Improved detail and prompt adherence; works with ComfyUI and local workflows

Typical users include content creators and influencers making Shorts or Reels, marketing and brand teams producing promos, filmmakers using it for previs, and developers who want local or custom pipelines. More information is available at https://www.jxp.com/ltx/ltx-2-3.
