SV4D
Overview :
Stable Video 4D (SV4D) is a generative model based on Stable Video Diffusion (SVD) and Stable Video 3D (SV3D). It takes a single perspective video and generates multiple new perspective videos (4D image matrix) of the same object. The model is trained to generate 40 frames (5 video frames x 8 camera angles) at a resolution of 576x576, given 5 reference frames of the same size. By running SV3D to produce a track video, this track video can then be used as a reference view for SV4D, with the original video serving as reference frames for 4D sampling. The model also generates longer new perspective videos by using the initial generated frame as an anchor point and performing dense sampling (interpolation) for the remaining frames.
Target Users :
Artists, designers, educators, and researchers. SV4D can help them generate new perspective videos for art creation, design showcases, or educational presentations.
Use Cases
An artist uses SV4D to create videos of a sculpture from different angles for an art exhibition.
A designer utilizes this model to generate multi-perspective showcase videos for a product, enhancing the presentation.
An educator employs SV4D to create multi-perspective videos for complex scientific concepts, aiding student comprehension.
Features
Generate a 4D image matrix with 40 frames at a resolution of 576x576.
Use SV3D to create a track video as a reference view for SV4D.
Utilize the input video as reference frames for 4D sampling.
Generate longer new perspective videos through dense sampling (interpolation) of the remaining frames.
Suitable for creating artworks and design processes.
Applicable in educational and creative tools.
Used for research on generative models, including understanding the limitations of these models.
How to Use
1. Prepare a video with 5 reference frames, each with a resolution of 576x576.
2. Use the SV3D model to generate a track video, which will serve as the reference view for SV4D.
3. Input both the track video and the original video as reference frames into the SV4D model.
4. Run the SV4D model to generate a 4D image matrix.
5. If desired, use the generated first frame as an anchor point to perform dense sampling (interpolation) for generating a longer new perspective video.
6. Check if the generated video meets the expected effects and make necessary adjustments.
7. Apply the generated video for art projects, design presentations, or educational demonstrations.

Animate Anyone
Animate Anyone aims to generate character videos from static images driven by signals. Leveraging the power of diffusion models, we propose a novel framework tailored for character animation. To maintain consistency of complex appearance features present in the reference image, we design ReferenceNet to merge detailed features via spatial attention. To ensure controllability and continuity, we introduce an efficient pose guidance module to direct character movements and adopt an effective temporal modeling approach to ensure smooth cross-frame transitions between video frames. By extending the training data, our method can animate any character, achieving superior results in character animation compared to other image-to-video approaches. Moreover, we evaluate our method on benchmarks for fashion video and human dance synthesis, achieving state-of-the-art results.
