Quick Start

Environment Setup

• Tested System Environment: Centos 7.2/Ubuntu 22.04, Cuda >= 12.1
• Tested GPUs: A100(80G) / RTX4090D (24G) / V100(16G)
• Tested Python Version: 3.10 / 3.11

🛠️Installation for Windows

Please use the one-click installation package to get started quickly for Quantified version.

🛠️Installation for Linux

1. Create a conda environment

conda create -n echomimic_v3 python=3.10
conda activate echomimic_v3

2. Other dependencies

pip install -r requirements.txt

🧱Model Preparation

Models	Download Link	Notes
Wan2.1-Fun-V1.1-1.3B-InP	🤗 Huggingface	Base model
wav2vec2-base	🤗 Huggingface	Audio encoder
EchoMimicV3-preview	🤗 Huggingface	Our weights
EchoMimicV3-preview	🤗 ModelScope	Our weights

-- The weights is organized as follows.

🔑 Quick Inference

python infer.py

For Quantified GradioUI version:

python app_mm.py

images, audios, masks and prompts are provided in datasets/echomimicv3_demos

Tips

• Audio CFG: Audio CFG audio_guidance_scale works optimally between 2~3. Increase the audio CFG value for better lip synchronization, while decreasing the audio CFG value can improve the visual quality.
• Text CFG: Text CFG guidance_scale works optimally between 3~6. Increase the text CFG value for better prompt following, while decreasing the text CFG value can improve the visual quality.
• TeaCache: The optimal range for teacache_threshold is between 0~0.1.
• Sampling steps: 5 steps for talking head, 15~25 steps for talking body.
• ​Long video generation: If you want to generate a video longer than 138 frames, you can use Long Video CFG.
• Try setting partial_video_length to 81, 65 or smaller to reduce VRAM usage.
