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.
