hpcaitech/Open-Sora ? reverse-engineered prompt

I want to build an open-source project like OpenAI's Sora for video generation. The main goal is to create a user-friendly and efficient platform that can produce high-quality videos from text prompts. Let's call it Open-Sora.

The core functionality should be text-to-video, but it should also support other modes like image-to-video and video-to-video. Users should be able to control the output, like generating videos of varying lengths from a few seconds up to 15 seconds, and at different resolutions and aspect ratios.

Please build this in Python. Set up the complete pipeline, including scripts for training the models and running inference. To make it easy for people to play with, wrap the generation logic in a simple Gradio web demo. Pull in the necessary libraries for diffusion models and transformers. You can look up the latest efficient training techniques if you need to.
