/openapi/v2/rhart-video/ltx-2.3/text-to-video
Lightricks' open-source text-to-video foundation model released March 2026. A new 4x larger text connector significantly improves understanding of complex prompts, with greatly enhanced accuracy in rendering multiple subjects, spatial relationships, and stylistic instructions. The rebuilt VAE delivers sharper details while an upgraded vocoder enables clearer synchronized audio generation. Supports native 1080p in both portrait and landscape formats, with multiple frame rates (24/48fps), outputting complete audio-visual content in 5-20 seconds without post-production dubbing.

Smooth and silky camera movements, rapidly skimming low past buildings and streets, evoking a strong sense of speed and flight immersion. Cinematic dynamic lighting, stable and steady, in 4K ultra-high-definition quality.
