Lightricks has released the revolutionary open source video generation model LTX Video (LTXV). This model is based on the diffusion transformer architecture and has 2 billion parameters. It was natively integrated with ComfyUI on the first day of release, attracting widespread attention in the industry. Its efficient generation speed, excellent picture quality, and convenience and ease of use all indicate that video generation technology has entered a new stage of development.
Lightricks recently released the revolutionary open source video generation model LTX Video (LTXV for short). This model based on the diffusion transformer (DiT) architecture has 2 billion parameters and achieved native integration with ComfyUI on the first day of release. , triggering strong repercussions in the industry.
This breakthrough video generation model delivers impressive performance. It can generate video content with a resolution of 768×512 pixels at 24 frames per second, which is even faster than the video playback speed itself. Specifically, LTXV can generate video content up to 5 seconds (121 frames) in just 4 seconds. This ultra-efficient processing power brings a revolutionary work experience to creators.
In terms of technical implementation, LTXV uses bfloat16 precision and can run efficiently on mainstream graphics cards such as NVIDIA RTX4090, ensuring video quality while optimizing memory usage. Its diffusion transformer architecture not only ensures the smoothness of picture transitions, but also effectively solves common problems such as object deformation, maintaining stable picture quality even when generating long videos.
The seamless integration of LTXV and ComfyUI further demonstrates its user-friendly design concept. Creators can directly search and use the dedicated "LTXVideo" node through ComfyUI Manager. This convenient workflow greatly lowers the threshold for use. By combining LTXV's real-time rendering capabilities with ComfyUI's powerful interface, creators gain an unprecedented video creation platform.
It is worth noting that the release of LTXV is not only a technological breakthrough, but also represents the democratization trend of creative technology. By making advanced video generation technology accessible, Lightricks provides a creative tool full of possibilities for creators from all backgrounds. As the ComfyUI community begins to explore the potential of LTXV, we can expect to see more innovative application scenarios emerge.
The release of LTXV marks that video generation technology has entered a new stage of development. Its excellent performance and convenient use experience will have a profound impact on the creative industry and open a new era of video content creation.
