## Description

EchoMimic V2 is an AI video generation pipeline and computer vision animation model designed to produce synthetic human animations. It functions as a generative framework that creates semi-body videos by aligning a static reference image with pose movements extracted from a driving video.

The system utilizes a diffusion-based generation process combined with latent space compression and a temporal attention mechanism to ensure smooth transitions between frames. It maintains consistent person identity through reference-based encoding and guides spatial placement via pose-driven motion conditioning.

The project includes capabilities for multi-stage image refinement to improve facial detail and sharpness. It also provides tools for animation dataset preparation, including the downloading and preprocessing of video data into formats required for model training and inference.
