LTX-Video

LTX-Video is Lightricks' open video generation line built on a Diffusion Transformer, notable for pushing generation speed: the distilled variants need as few as 8 diffusion steps and can run faster than real time on an H100 GPU. The repository covers text-to-video, image-to-video, multi-keyframe conditioning, and forward or backward video extension, and the LTX-2 release adds synchronized audio generation with output up to roughly 10 seconds, 50 frames per second, and native 4K resolution. Model options span a 13B full model, 13B and 2B distilled versions, and FP8 quantized variants for lower VRAM, with macOS supported through MPS. Weights ship under the OpenRail-M license, permitting commercial use, and the ecosystem includes official ComfyUI workflows, Hugging Face Diffusers support, and community tools like LTX-VideoQ8. It attracts creators and developers who want controllable local video generation without datacenter-scale hardware.
