Model overview

ltx-video is a groundbreaking video generation model developed by Lightricks, the creators of popular photo and video editing apps like Facetune and Videoshop. It is the first DiT-based video generation model capable of producing high-quality videos in real-time, at a resolution of 768x512 and 24 FPS. This makes it significantly faster than traditional video generation models, allowing users to generate videos faster than they can be watched.

Similar models like lcm-video2video, video-crafter, and frames-to-video also focus on video generation, but they typically require more time and computational resources to produce high-quality results. In contrast, ltx-video is able to generate realistic and diverse video content in real-time, making it a significant advancement in the field of video AI.

Model inputs and outputs

ltx-video takes a text prompt as the main input, which is used to guide the generation of the video. The model can also accept an optional input image, which can be used as the starting frame for the generated video. The output is an array of video frames, represented as image URIs, that can be combined into a video.

Inputs

Prompt: A detailed, descriptive text prompt that provides instructions for the model on what to generate. The prompt should be a single paragraph that includes specific details about the desired scene, characters, actions, and environment.
Optional Image: An input image that can be used as the starting frame for the generated video.
