Generating realistic sound for video (V2A) is a major challenge, especially for Foley—the art of creating sound effects synchronized with on-screen actions. Current benchmarks for this task are flawed. They are often contaminated with speech, music, and off-screen sounds, making it impossible to truly evaluate a model's ability to generate accurate, synchronized Foley. This misalignment leads to misleading conclusions about model performance.

We introduce FoleyBench, the first large-scale benchmark designed for evaluating Foley-style V2A generation.

* **High-Quality, Foley-Focused:** Contains 5,000 video-audio-text triplets meticulously curated for Foley. All content is non-speech/non-music, with strong causal links between visible actions and their sounds.
* **Diverse Category Coverage:** Ensures a broad and balanced distribution across the Universal Category System (UCS), addressing a key limitation of previous datasets.
* **Rich Metadata for Deep Analysis:** Each clip is annotated with source complexity (single vs. multi-source) and sound type (discrete vs. continuous), enabling fine-grained analysis of model strengths and weaknesses.

## Dataset Description

- **Total Videos**: 5,000
- **Video Duration**: ~10 seconds each
- **Total Size**: ~13 GB
- **Format**: MP4 with embedded audio
- **Resolution**: Various (mostly 640x360)

## Dataset Structure

- **foleybench.csv**: Metadata file with video information including captions, duration, and source metadata
- **data/train-0-of-9.parquet** ... **data/train-9-of-9.parquet**: Ten shards with embedded base64 video content (500 videos per shard)

## Features

Each example in the dataset contains:
- `key`: Unique identifier for the video
- `duration`: Video duration in seconds
- `dataset`: Source dataset name
- `width`: Video width in pixels
- `height`: Video height in pixels
- `caption`: Text description of the video content
- `discrete_vs_rest`: Discrete/rest label
- `source_type`: Source type label
- `sound_type`: Sound type label
- `ucs_category`: UCS category label
- `audioset_category`: AudioSet category label
- `metadata`: JSON string with source information (YouTube ID, timestamps, etc.)
- `video_path`: Relative path of the source video
- `video_data`: Base64-encoded video content

## Usage

```python
from datasets import load_dataset
import base64

# Load the dataset
dataset = load_dataset("FoleyBench/foleybench")

# Access video data
first_example = dataset["train"][0]
print(f"Caption: {first_example['caption']}")
print(f"Duration: {first_example['duration']} seconds")

# Decode video
video_b64 = first_example["video_data"]
video_bytes = base64.b64decode(video_b64)

# Save video to file
with open("video.mp4", "wb") as f:
    f.write(video_bytes)
```
