# Human Motion

EchoMimicV2 is an upper-body animation technology developed by the Ant Group's Terminal Technology Department at Alipay. It generates high-quality animated videos by leveraging reference images, audio clips, and a series of gestures to ensure the coherence between audio content and upper-body motions. This technology simplifies the previously complex animation production process through an Audio-Pose dynamic coordination strategy, enhancing the expressiveness of upper-body details, facial features, and gestures while reducing conditional redundancy. Additionally, it seamlessly integrates avatar data into the training framework using a head-part attention mechanism, which can be omitted during inference, thereby facilitating the animation production process. EchoMimicV2 also features a specific-stage denoising loss designed to guide motion, detail, and low-level quality of the animation at specific stages. This technology has surpassed existing methods in both quantitative and qualitative assessments, demonstrating its leading position in the field of upper-body human animation.

Developed jointly by Tencent and Shanghai Jiao Tong University, MimicMotion is a high-quality human motion video generation model. This model achieves controllability in the video generation process through confidence-aware pose guidance, improving temporal smoothness and reducing image distortion. Employing an advanced image-to-video diffusion model combined with a spatiotemporal U-Net and PoseNet, it can generate videos of arbitrary length with high quality based on pose sequence conditions. MimicMotion significantly outperforms prior methods in several aspects, including hand generation quality and accurate adherence to reference poses.

Movmi is an AI-powered motion capture tool that captures human body movements from 2D media data (images and videos), providing developers with high-quality human motion capture solutions. The entire capture process is completed in the cloud, requiring no high-end equipment. Movmi supports capturing footage from various cameras, including smartphones and professional cameras, suitable for diverse life scenarios and even supporting multi-character scenes. Movmi also offers a full-text atlas character library for various animation projects. Movmi's membership plans are divided into Bronze, Silver, and Gold, offering different levels of features and experiences. Users can use the output FBX files in any 3D environment.
