Controlnet for Wan2.2 A14B (hed)
This repo contains the code for controlnet module for Wan2.2. See Github code.
Same approach as controlnet for Wan2.1.
For ComfyUI
Use the cool ComfyUI-WanVideoWrapper.
The latest version of the diffusers is required.
You can install it like this:
pip install git+https://github.com/huggingface/diffusers.git
Inference examples
Simple inference with cli
python -m inference.cli_demo \
--video_path "resources/bubble.mp4" \
--prompt "Close-up shot with soft lighting, focusing sharply on the lower half of a young woman's face. Her lips are slightly parted as she blows an enormous bubblegum bubble. The bubble is semi-transparent, shimmering gently under the light, and surprisingly contains a miniature aquarium inside, where two orange-and-white goldfish slowly swim, their fins delicately fluttering as if in an aquatic universe. The background is a pure light blue color." \
--controlnet_type "hed" \
--base_model_path Wan-AI/Wan2.2-T2V-A14B \
--controlnet_model_path TheDenk/wan2.2-t2v-a14b-controlnet-hed-v1
