A new open source AI video generator just came out swinging. LTX V13B is here. Imagine generating AI video up to 30 times faster than anything out there and that is without sacrificing high detail and believable motion. All thanks to optimized kernels and smarter VAE compression. This model uses something called multiscale rendering. Every scene starts with a coarser more rough outline which by the way gives you vast previews in ltx but your final result will have razor shar, high resolution detail and oh yeah open source so you can run this all on your consumer grade GPU as well. Check it out on GitHub and hugging face pages, dive into the code yourself, customize pipelines and help develop the future of AI video technology. But if you're not a tech savvy dev in LTX Studio itself, you'll have a fantastic UI to try out this brand new model. Control start and end keyframes steer camera motion Click the link down below.
