Dataset statistics

Dataset	Size	Video		Query		Response
		Obs.	Fut.	OEQ	MCQ	Observation	Reasoning	Prediction	Answer
D1	42,673	Unpartitioned		—	—	Caption
D2	15,290	✓	✓	✓	—	✓	✓	✓	—
D3	2,885	✓	—	—	✓	✓	✓	✓	✓

Size is the number of samples. Obs. and Fut. denote observed and future video segments. OEQ and MCQ denote open-ended and multiple-choice questions. D1 video segments are not assigned observed or future roles; each response is a caption.

D1	D1/D1_metadata.json	D1/videos/
D2	D2/D2_metadata.json	D2/videos/

Video files are grouped into numbered subdirectories inside videos/; the exact path is given in the metadata.

Metadata format

Each metadata file is a JSON object keyed by sample ID. Every entry contains only video, query, and answer.

Field	Meaning
Sample ID (object key)	Unique identifier of the sample within the dataset.
video	Video path relative to the repository root. For D2, an object containing the observation and future video paths.
query	Question text. Empty for D1; an open-ended question for D2; a question with its choices for D3.
answer	Complete response as a single text string. Original text, tags, line breaks, and tag order are preserved; the response is not split into separate fields.

The examples below illustrate the structure; ellipses stand for sample text.

D1

D1/D1_metadata.json maps each sample ID to its video segment, an empty query, and a caption.

{
  "D1_example": {
    "video": "D1/videos/000/D1_example.mp4",
    "query": "",
    "answer": "..."
  }
}

D2

D2/D2_metadata.json maps each sample ID to its observed and future video segments, an open-ended question, and the complete response text.

{
  "D2_example": {
    "video": {
      "observation": "D2/videos/000/D2_example_observation.mp4",
      "future": "D2/videos/000/D2_example_future.mp4"
    },
    "query": "...",
    "answer": "<observation>...</observation>\n<reasoning>...</reasoning>\n<latent></latent>\n<prediction>...</prediction>"
  }
}

D3

D3/D3_metadata.json maps each sample ID to its observed video segment, a multiple-choice question including its choices, and the complete response text.

{
  "D3_example": {
    "video": "D3/videos/000/D3_example.mp4",
    "query": "...\n\nOptions:\nA. ...\nB. ...\nC. ...\nD. ...",
    "answer": "<observation>...</observation>\n<reasoning>...</reasoning>\n<latent></latent>\n<prediction>...</prediction><answer>...</answer>"
  }
}
