💡 Usage Tips

• Reference Image Preparation: Please upload cropped face images (recommended resolution: 512x512) as reference. Avoid using full-body photos to ensure optimal identity preservation.
• Inference Steps: For simple scenes, you can reduce the sampling steps to 20 to significantly decrease inference time.

  Note: Our internal model based on Seedance1.0 achieves high quality in under 8 steps. Feel free to experience it at CapCut.

• Best Quality: For the highest fidelity results, we recommend using a resolution of 1280x720.
• Enhanced Pose Detection: We have resolved the previous pose detection issue by introducing DreamID-V-Wan-1.3B-DWPose. This significantly improves stability and robustness in pose extraction.

Installation

Install dependencies:

# Ensure torch >= 2.4.0
pip install -r requirements.txt

DreamID-V-Wan-1.3B

• Single-GPU inference

python generate_dreamidv.py \
    --size 832*480 \
    --ckpt_dir wan2.1-1.3B path \
    --dreamidv_ckpt dreamidv.pth path  \
    --sample_steps 20 \
    --base_seed 42

• Multi-GPU inference using FSDP + xDiT USP

pip install "xfuser>=0.4.1"
torchrun --nproc_per_node=2 generate_dreamidv.py \
    --size 832*480 \
    --ckpt_dir wan2.1-1.3B path \
    --dreamidv_ckpt dreamidv.pth path  \
    --sample_steps 20 \
    --dit_fsdp \
    --t5_fsdp \
    --ulysses_size 2 \
    --ring_size 1 \
    --base_seed 42

DreamID-V-Wan-1.3B-DWPose

Please ensure the pose estimation models are placed in the correct directory as follows:

DreamID-V/
└── pose/
    └── models/
        ├── dw-ll_ucoco_384.onnx 
        └── yolox_l.onnx         

• Single-GPU inference

python generate_dreamidv_dwpose.py \
    --size 832*480 \
    --ckpt_dir wan2.1-1.3B path \
    --dreamidv_ckpt dreamidv.pth path  \
    --sample_steps 20 \
    --base_seed 42
