Lightricks' next-generation image-to-video foundation model, delivering comprehensive quality improvements over the LTX-2 series. A completely rebuilt VAE architecture significantly enhances sharpness in hair, text, and edge details while greatly reducing frozen frames and static Ken Burns effects for more authentic motion. Native 9:16 portrait support enables direct creation of social media-native content without cropping. Generates matching ambient sound effects and visual motion in a single pass, achieving perfect audio-visual alignment within 5-20 second durations, truly bringing static photos to life.
