DiffSynth Studio

What is the project about?

DiffSynth Studio is a Diffusion engine designed for image and video generation. It's built to be compatible with open-source diffusion models while enhancing computational performance.

What problem does it solve?

It addresses limitations in existing diffusion models, such as resolution constraints and computational efficiency, particularly in video synthesis. It also aims to make advanced image and video generation techniques more accessible. It allows for longer video generation, and improved control over image generation.

What are the features of the project?

  • Compatibility: Works with various open-source diffusion models (Stable Diffusion, Stable Video Diffusion, ControlNet, AnimateDiff, IP-Adapter, and more).
  • Enhanced Performance: Restructured architectures (Text Encoder, UNet, VAE) for better computational efficiency.
  • Video Synthesis:
    • Text-to-video generation (using models like CogVideoX-5B, HunyuanVideo).
    • Long video generation (ExVideo).
    • Video editing.
    • Video interpolation.
    • Self-upscaling.
    • Toon shading (Diffutoon).
    • Video stylization.
  • Image Synthesis:
    • High-resolution image generation.
    • Controllable image generation (ControlNet).
    • LoRA fine-tuning.
    • Entity-Level Controlled Image Generation (EliGen).
    • Aesthetic understanding integration (ArtAug).
  • WebUI: Provides a user-friendly interface (Gradio and Streamlit) with a painter tool for interactive image creation.
  • Advanced VRAM Management: Efficient use of VRAM, enabling high-resolution video generation even with limited resources.
  • Extensible: Supports a wide range of models and techniques, with ongoing development and addition of new features.

What are the technologies used in the project?

  • Python
  • Diffusion Models (Stable Diffusion, Stable Video Diffusion, etc.)
