This is a simplified guide to an AI model called Ltx-Video maintained by Lightricks. If you like these kinds of analysis, you should join AImodels.fyi or follow us on Twitter.
Model overview
ltx-video is the first DiT-based video generation model capable of generating high-quality videos in real-time. It produces 24 FPS videos at a 768x512 resolution faster than they can be watched. The model is trained on a large-scale dataset of diverse videos and can generate high-resolution videos with realistic and varied content. This sets it apart from similar models like LTX-Video and LTX-Video, which also use DiT architectures for video generation but may not match the real-time performance or scale of the data.
Model inputs and outputs
The ltx-video model takes in text prompts or image+text prompts and generates corresponding high-quality video frames. The model is optimized to work on resolutions divisible by 32 and frame counts divisible by 8 + 1, with best results under 720x1280 resolution and 257 frames.
Inputs
- Prompt: Detailed, chronological descriptions of actions and scenes, up to 200 words, focused on specific movements, appearances, camera angles and environmental details.
- Image (optional): An optional input image to use as the starting frame for the generated video.
- Resolution/Frame parameters: Users can specify the target resolution, aspect ratio, number of frames, guidance scale, and inference steps.
Outputs
- Video: The model outputs a sequence of video frames matching the provided prompt and parameters, encoded as a series of image URLs.
