What is LTX Video?
LTX Video is an open-weights generative video foundation model developed by Lightricks. Designed with a focus on real-time inference latency and hardware efficiency, LTX Video generates high-resolution video clips up to 5 seconds long faster than real-time playback on standard enterprise GPUs. Utilizing a spatial-temporal DiT architecture and optimized latent representations, LTX Video excels at rapid camera movements, camera pans, and dynamic object transformations, making it ideal for interactive video creation tools, gaming prototypes, and real-time social content pipelines.
