Light-Syn Dataset
📄 Paper | 🚀 Project Page | 💻 GitHub
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:
Light-Syn/
├── scene0/
│ ├── input.mp4 # Input video
│ ├── target.mp4 # Target video under new view / lighting
│ ├── render.mp4 # Rendered result
│ ├── mask.mp4 # Rendered valid-region mask
│ ├── relit_render.mp4 # Relit rendering result
│ ├── prompt.txt # Text prompt describing the scene
│ ├── id.txt # Reference frame index (integer)
│ ├── ref_light.png # Reference lighting image (required for reference-based relighting)
│ └── scene_000.exr # HDR environment map (required for HDR-based relighting)
├── scene1/
│ └── ...
