# motion_example_0801

This dataset contains **2,000,000 motion examples** distributed as **1,954 uncompressed tar archives**, totaling 1,277,023,825,920 bytes (approximately 1.28 TB).

Each example has three corresponding files:

| Directory | Format | Contents |
| --- | --- | --- |
| `human_motion/` | `.pt` | SMPL motion data |
| `motion_caption/` | `.json` | Motion descriptions |
| `rendered_videos/` | `.mp4` | Stickman renderings of the motion |

Archives are named `motion_example_0801_00000.tar` through `motion_example_0801_01953.tar`. The first 1,953 archives contain 1,024 examples each; the last contains 128. `archive_index.tsv` lists the example count for each archive.

The first archive also contains these five metadata files at its beginning:

- `metadata.jsonl`
- `metadata_caption.jsonl`
- `metadata_classification.jsonl`
- `metadata_objects.jsonl`
- `metadata_render.jsonl`

In `metadata_caption.jsonl`, each `video_caption` combines descriptions of its two source motion segments. One of eight transition templates is randomly selected, with gender-neutral person references. These captions retain descriptions of the source videos, including their appearance and setting, and are not literal descriptions of the stickman renderings. The `video_path` field is empty; rendering information is provided in `metadata_render.jsonl`.

## Verify and extract

Download all archive shards together with `SHA256SUMS` and `archive_index.tsv`. Verify the archives before extraction:

```bash
sha256sum -c SHA256SUMS
```

Extract every archive into the same directory. Archive member paths are relative to the dataset root and do not include an additional enclosing directory:

```bash
mkdir -p motion_example_0801
for archive in motion_example_0801_*.tar; do
    tar -xf "$archive" -C motion_example_0801
done
```

The extracted directory contains the five metadata files and the three data directories listed above. The tar files are uncompressed, so retaining both the archives and extracted dataset requires space for both copies.
