# dataset

This directory stores the final released VidLLVIP paired infrared-visible video clips. The repository does not include large video files by default, so please download them separately.

## Download

- Option 1: Download from [Hugging Face](https://huggingface.co/datasets/jianfeng0369/VidLLVIP)
- Option 2: Download from [Quark Drive](https://pan.quark.cn/s/e3abe425aa5f?pwd=E5gv)

After downloading, extract `dataset.zip` into this directory so that it matches the structure below.

## Expected File Structure

```text
dataset/
  README.md
  ir/
    01_0000_0005.mp4
    01_0005_0010.mp4
    ...
  vi/
    01_0000_0005.mp4
    01_0005_0010.mp4
    ...
```

Videos with the same file name under `ir/` and `vi/` form one paired sample. For example, `ir/01_0000_0005.mp4` and `vi/01_0000_0005.mp4` are the infrared and visible videos from the same time interval.

The file name format is:

```text
{source_id}_{start_second}_{end_second}.mp4
```

The final dataset contains `894` paired 5-second clips. Each clip is `1280 x 1024`, `25 FPS`, `125` frames, and has no audio.
