About LTX-2.3
LTX-2.3 is Lightricks' multimodal video generation model, producing synchronized video and audio in a single pass rather than layering sound on afterward. It runs in three modes: type a text prompt to generate video from scratch, upload a starting image to animate it into motion, or drive the output directly from an audio clip so the visuals sync to the sound, with clip length following the audio. Text and image mode clips run 6 to 10 seconds, generated at resolutions from 1080p up to full 4K, in either landscape or portrait orientation. Native audio generation is on by default in the text and image modes, so dialogue and ambient sound arrive built into the render — no separate audio pass needed. It's built for production-ready output: temporal stability and motion coherence hold up across longer clips and higher resolutions, suited to creative and marketing pipelines that need polished results fast.
