Tora
Overview :
Tora is a video generation model based on Diffusion Transformers (DiT), which integrates text, visual, and trajectory conditions to achieve precise control over video content dynamics. Tora is designed to fully leverage the scalability of DiT, allowing for the generation of high-quality video content across different durations, aspect ratios, and resolutions. The model excels in motion fidelity and physical world motion simulation, offering new possibilities for video content creation.
Target Users :
The primary audience for Tora includes video content creators, animators, and visual effects specialists who require a technology that allows for precise control over video dynamics and motion. Tora offers an innovative approach for generating high-quality video content, particularly suited for complex projects that demand highly customizable dynamic effects.
Use Cases
Generate a natural landscape video featuring a specific trajectory, such as floating roses against a snow-capped mountain backdrop.
Create a virtual scene with smooth dynamics, such as seagulls flying underwater amidst vibrant coral reefs.
Produce a commercial advertisement with precise motion control, like a red helium balloon rising in the desert.
Features
Trajectory Extractor (TE): Encodes arbitrary trajectories into hierarchical spatiotemporal motion patches.
Spatiotemporal Diffusion Transformer: Combines 3D video compression networks to effectively preserve motion information between frames.
Motion Guided Fusionizer (MGF): Seamlessly injects multi-level motion conditions into DiT blocks using adaptive normalization layers.
High motion fidelity: Achieves precise control over video dynamics, generating videos consistent with physical world motion.
Multi-resolution support: Capable of generating high-quality videos in various resolutions.
Long-duration video generation: Supports the creation of video content with extended durations.

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.
