LTX Video (LTXV): a real-time video generation open source model for generating high quality video

General Introduction

LTX-Video is the first DiT (Diffusion Transformer) based real-time video generation model developed by Lightricks. The model is capable of generating high-quality video at 24 frames per second at 768x512 resolution, faster than the time it takes to watch the video.LTX-Video has been trained on a large and diverse video dataset to generate high-resolution videos with realism and diverse content. The model is designed to provide a fast and efficient video generation solution for a variety of creative and professional application scenarios.

LTXV has obvious drawbacks, don't enter a simple cue word, give a detailed description of the video screen or expand on the cue word.
