We provide 10 video samples with annotations for quick review.

Each video is named in the format `video_id`_`obj_id`.

The `annotation.json` file follows the structure below:

```json
{
    video_id: [
        {
        "exp": "A yellow and white cat",    # the object description
        "obj_id": 1,                        # the object ID
        "type": "static"                    # the description type: static / dynamic / hybrid.
        }
    ], ...
}
