Paper Arxiv Project Page

Generating semantically and temporally aligned audio content in accordance with video input has become a focal point for researchers, particularly following the remarkable breakthrough in text-to-video generation. We aim to offer insights into the video-to-audio generation paradigm.

Install

First install the python requirements. We recommend using conda:

conda create -n vta-ldm python=3.10
conda activate vta-ldm
pip install -r requirements.txt

Then download the checkpoints from huggingface, we recommend using git lfs:

mkdir ckpt && cd ckpt
git clone https://huggingface.co/ariesssxu/vta-ldm-clip4clip-v-large
# pull if large files are skipped:
cd vta-ldm-clip4clip-v-large && git lfs pull

Model List

  • ✅ VTA_LDM (the base model)
  • 🕳️ VTA_LDM+IB/LB/CAVP/VIVIT
  • 🕳️ VTA_LDM+text
  • 🕳️ VTA_LDM+PE
  • 🕳️ VTA_LDM+text+concat
  • 🕳️ VTA_LDM+pretrain+text+concat

Inference

Put the video pieces into the data directory. Run the provided inference script to generate audio content from the input videos:

bash inference_from_video.sh

You can custom the hyperparameters to fit your personal requirements. We also provide a script that can help merge the generated audio content with the original video based on ffmpeg:

bash tools/merge_video_audio

Training

TBD. Code Coming Soon.
