## Overview
Video reasoning grounds intelligence in spatiotemporally consistent visual environments that go beyond what text can naturally capture, 
enabling intuitive reasoning over motion, interaction, and causality. Rapid progress in video models has focused primarily on visual quality. 
Systematically studying video reasoning and its scaling behavior suffers from a lack of video reasoning (training) data. 
To address this gap, we introduce the Very Big Video Reasoning (VBVR) Dataset, an unprecedentedly large-scale resource spanning 200 curated reasoning tasks 
and over one million video clips—approximately three orders of magnitude larger than existing datasets. We further present VBVR-Bench, 
a verifiable evaluation framework that moves beyond model-based judging by incorporating rule-based, human-aligned scorers, 
enabling reproducible and interpretable diagnosis of video reasoning capabilities. 

For more details, please refer to the paper: [A Very Big Video Reasoning Suite](https://huggingface.co/papers/2602.20159).

## Sample Usage

To evaluate a model using the VBVR suite, you can use the official evaluation toolkit [VBVR-EvalKit](https://github.com/Video-Reason/VBVR-EvalKit):

```bash
# Install the toolkit
git clone https://github.com/Video-Reason/VBVR-EvalKit.git && cd VBVR-EvalKit
python -m venv venv && source venv/bin/activate
pip install -e .

# Setup a model (example: SVD)
bash setup/install_model.sh --model svd --validate

# Inference
python examples/generate_videos.py --questions-dir /path/to/VBVR-Bench-Data --output-dir ./outputs --model svd

# Evaluation (VBVR-Bench)
python examples/score_videos.py --inference-dir ./outputs
```

## Release Information
We are pleased to release the official **VBVR-Bench** test dataset, designed for standardized and rigorous evaluation of video-based visual reasoning models. 
The test split is designed along with the evaluation toolkit provided by Video-Reason at [VBVR-EvalKit](https://github.com/Video-Reason/VBVR-EvalKit).

After running evaluation, you can compare your model’s performance on the public leaderboard at [VBVR-Bench Leaderboard](https://huggingface.co/spaces/Video-Reason/VBVR-Bench-Leaderboard).

## Data Structure
The dataset is organized by domain and task generator. For example:

```bash
In-Domain_50/
  G-31_directed_graph_navigation_data-generator/
    00000/
      first_frame.png
      final_frame.png
      ground_truth.mp4
      prompt.txt
```
### Structure Description

- **In-Domain_50/Out-of-Domain_50**: Evaluation splits indicating whether samples belong to in-domain or out-of-domain settings.
- **G-XXX_task-name_data-generator**: A specific reasoning task category and its corresponding data generator.
- **00000-00004**: Individual sample instances.

Each sample directory contains:
- `first_frame.png`: The initial frame of the video
- `final_frame.png`: The final frame
- `ground_truth.mp4`: The full video sequence
- `prompt.txt`: The textual reasoning question or instruction
