+## Goal
 This project aims to create a simple and scalable repo, to reproduce [Sora](https://openai.com/sora) (OpenAI, but we prefer to call it "CloseAI" ) and build knowledge about Video-VQVAE (VideoGPT) + DiT at scale. However, we have limited resources, we deeply wish all open-source community can contribute to this project. Pull request are welcome!!!
 
 本项目希望通过开源社区的力量复现Sora，由北大-兔展AIGC联合实验室共同发起，当前我们资源有限仅搭建了基础架构，无法进行完整训练，希望通过开源社区逐步增加模块并筹集资源进行训练，当前版本离目标差距巨大，仍需持续完善和快速迭代，欢迎Pull request！！！

+2. Train models that boost resolution and duration.
+
+- Extensions
+3. Conduct text2video experiments on landscape dataset.
