| # 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. |
