Hunyuan Video-Foley: AI-Powered Revolution in Sound Design

Sound tends to play a brilliant role in animation, TV, film, and gaming. Traditionally, Foley artists may produce the everyday sounds like clothing rustles, footsteps, and object collisions in a studio setting, which is a process that is both resource-heavy and time-consuming.

Now, Tencent's Hunyuan Video Foley has surely come up the with the sound design's new ear. By using the advanced AI models, it will automatically generate the high-quality and perfectly synchronized Foley sounds directly from the videos.

The breakthrough tends to reduce the production costs while maintaining the professional-grade audio quality. This post is all set to introduce what is the Hunyuan Video Foley and how to use it.

Part 1: What is Hunyuan Video Foley

Hunyuan Video Foley remains to be the end-to-end Text video to Audio framework developed by Tencent's Hunyuan lab. It takes both text prompts and video frames as input before generating the lifelike sound effects, aligning with the actions of the videos and the atmosphere of the video.

Key Features

• The Models couple with the optional text prompts and video frames to understand the environment and context.
• With this model, you'll be able to create 48kHz professional-level audio with stable and clear sound.
• It helps you to ensure the ambient sounds, collisions, and footsteps are perfectly aligned with video actions.
• Hunyuan video Foley tends to align the generated audio with the reference audio model for enhanced realism and clarity.

Part 2: How does Hunyuan Video Foley Work

Hunyuan Video Foley is built on the multi-model diffusion models and a large-scale dataset. It could work by looking at the following things.

1. Date Collection & Preprocessing

It is trained on over 100 000 hours of high-quality audio pairs with text annotations. You could easily filter out the poor-quality samples to improve the performance.

2. Multi-model Understanding

The model tends to process the video frames + text prompts to identify actions like footsteps, glass breaking, and contextual atmosphere.

3. Time Synchronization

It matches the sound events with the exact timestamps and the visual actions to ensure natural playback.

4. Representation Alignment

It tends to use a reference audio model during the training to align the frequency features, which could result in the more stable and realistic sound output.

5. Evaluation

It outperforms the existing AI sound generation models in human listening tests and objective benchmarks for sound clarity and Synchronization.

Part 3: How to Access and Use Hunyuan Video Foley

Where to get it

GitHub:

Source code and setup instructions are available on Tencent's official GetHub repository.

Hugging Face :

Pertained models may be downloaded from Hugging Face.

Gradio Demo :

A web interface might help you to upload a video before adding the prompts and generating the sound effects interactively.

Step-by-step guide to using the Hunyuan Video Foley

Step 1: Clone the GitHub Repo:

git clone https://github.com/Tencent-Hunyuan/HunyuanVideo-Foley

Then, you'll need to install the dependencies with pip install -r requirements.txt

Step 2: In this phase, you'll need to download the pretrained models from Hugging Face, which could require Git LFS.

Step 3: Run inference of the single video by following the command written below.
