# Light-Syn Dataset |

📄 **[Paper](https://arxiv.org/abs/2512.05115)** | 🚀 **[Project Page](https://lightx-ai.github.io/)** | 💻 **[GitHub](https://github.com/TQTQliu/Light-X)** |

|
## Introduction |
|
|
|
|
|
**Light-Syn** is a synthetic dataset designed for learning **controllable video generation** under varying **camera viewpoints** and **illumination conditions**. |
|
|
It is constructed via a synthetic data generation pipeline that produces **paired video samples** with controlled viewpoint and lighting variations from monocular visual inputs, and is introduced as training data for the **Light-X** framework, which enables joint control of camera motion and illumination in generative video models. |
|
|
|
|
|
> **Release Note** |
|
|
> The current public release of **Light-Syn** includes only the **static scene subset**, due to copyright and data usage constraints. |
|
|
> For access to the complete dataset (e.g., dynamic scenes), please contact **Tianqi Liu (tq_liu at hust.edu.cn)**. |

## Dataset Structure |
|
|
|
|
|
The dataset is organized as a collection of **per-sample folders**, where each folder corresponds to one scene and contains paired videos, text prompts, and lighting conditions. |
|
|
|
|
|
A high-level directory structure is as follows: |
|
|
|
|
|
``` |
|
|

|
|
│ ├── input.mp4 # Input video |

│ ├── target.mp4 # Target video under new view / lighting |
|
|

|
