Diffusion As Shader
Overview :
Diffusion as Shader (DaS) is an innovative video generation control model designed to achieve diverse control over video generation through a 3D perception diffusion process. This model utilizes 3D tracking videos as control inputs, supporting multiple video control tasks under a unified architecture, including mesh-to-video generation, camera control, motion transfer, and object manipulation. The main advantage of DaS lies in its 3D perception capabilities, significantly enhancing the temporal consistency of generated videos and demonstrating powerful control abilities with minimal data and short tuning times. Developed collaboratively by research teams from institutions like the Hong Kong University of Science and Technology, the model aims to advance video generation technology, providing more flexible and efficient solutions for fields such as filmmaking and virtual reality.
Target Users :
This product is designed for professionals requiring high-quality video generation and control, such as filmmakers, virtual reality developers, and game designers, enabling them to efficiently meet complex video production needs.
Use Cases
Convert a simple animated mesh into a high-quality video with detailed appearance and geometric features.
Generate a video with a specific camera movement trajectory based on a given text prompt.
Transfer motion from one video to another, achieving motion transfer.
Manipulate specific objects within the video, such as moving or rotating them, to meet specific production needs.
Features
Supports high-quality video generation from text prompts or images
Enables precise camera control, including up, down, left, right movements, and spiral motions
Converts simple animated meshes into visually rich videos
Supports object manipulation, such as moving or rotating specific objects
Facilitates motion transfer, transferring motion from one video to another
Enhances the temporal consistency of generated videos through 3D tracking videos
Allows model fine-tuning in a short time with minimal data
How to Use
1. Prepare the input data, such as text prompts, images, or simple animated meshes.
2. Use the tools provided by the DaS model (e.g., Depth Pro, SAM) for preprocessing the input data, like estimating depth maps and segmenting objects.
3. Generate 3D tracking videos as control inputs for video generation as needed.
4. Input the preprocessed data and 3D tracking videos into the DaS model for video generation.
5. Fine-tune the model parameters to optimize the quality and control of the generated video.
6. Output the generated video for subsequent editing and application.
