Summary

BindWeave is a unified framework for subject-consistent video generation, capable of handling both single and multi-subject prompts. It targets researchers and engineers in AI video synthesis, offering high-fidelity video creation by integrating multimodal large language models with diffusion transformers.

How It Works

The core architecture couples a pretrained multimodal large language model (MLLM) with a Diffusion Transformer (DiT). BindWeave achieves cross-modal integration through entity grounding and representation alignment. The MLLM parses complex user prompts, generating subject-aware hidden states that precisely condition the DiT for generating high-fidelity videos, ensuring subject consistency across generations.

Quick Start & Requirements

Installation involves cloning the repository and running bash build_env.sh. Key prerequisites include:

• Switching between feature_extraction and infer Git branches for specific steps.
• Downloading the WanX 2.1 14B model (Wan-AI/Wan2.1-I2V-14B-720P-Diffusers) and the BindWeave 14B model (ByteDance/BindWeave) via Hugging Face CLI.
• Converting downloaded weights using python convert_ckpt.py.
• Updating configuration files (configs/inference/inference_model_s2v.json) to point to downloaded model components.
• Dependencies include huggingface_hub[cli].
