This repository includes official codes for "Seeing and Hearing: Open-domain Visual-Audio Generation with Diffusion Latent Aligners (CVPR 2024)".

🔮 Method

Framework Overview. Our approach is versatile and can tackle four tasks: joint video-audio generation (Joint-VA), video-to-audio (V2A), audio-to-video (A2V), and image-to-audio (I2A). By leveraging a multimodal binder, e.g., pretrained ImageBind, we establish a connection between isolated generative models that are designed for generating a single modality. This enables us to achieve both bidirectional conditional and joint video/audio generation.

🔆 Abstract

Video and audio content creation serves as the core technique for the movie industry and professional users. Recently, existing diffusion-based methods tackle video and audio generation separately, which hinders the technique transfer from academia to industry. In this work, we aim at filling the gap, with a carefully designed optimization-based framework for cross-visual-audio and joint-visual-audio generation. We observe the powerful generation ability of off-the-shelf video or audio generation models. Thus, instead of training the giant models from scratch, we propose to bridge the existing strong models with a shared latent representation space. Specifically, we propose a multimodality latent aligner with the pre-trained ImageBind model. Our latent aligner shares a similar core as the classifier guidance that guides the diffusion denoising process during inference time. Through carefully designed optimization strategy and loss functions, we show the superior performance of our method on joint video-audio generation, visual-steered audio generation, and audio-steered visual generation tasks.

   mkdir ckpt; cd ckpt
   git clone https://huggingface.co/cvssp/audioldm-m-full
   cd ..
   

   (2) Download imagebind ckpts imagebind_huge.pth from the official repo. Put the ckpts to imagebind/.checkpoints/.

   mkdir imagebind/.checkpoints; cd imagebind/.checkpoints
   wget https://dl.fbaipublicfiles.com/imagebind/imagebind_huge.pth
   cd ../..
   

   (3) Download qwen ckpts from the huggingface repo. Put the ckpts to qwen_ckpt/.

   mkdir qwen_ckpt; cd qwen_ckpt
   git clone https://huggingface.co/Qwen/Qwen-VL-Chat
   cd ..
