Motion Example 0801 Dance
This is the dance subset of Motion Example 0801.
It contains 291,952 motion examples in 30 dance categories, selected using
motion_type.startswith("dance_") in metadata_classification.jsonl.
The original sample IDs, names, relative paths, and metadata contents are preserved.
The separate fitness_dance_workout category is not part of this subset.
Archives
The dataset is stored in 286 uncompressed tar archives, retaining the original
directory numbers from 00466 to 00751:
motion_example_0801_dance_00466.tar: 645 examples and all five metadata files.motion_example_0801_dance_00467.tarthroughmotion_example_0801_dance_00750.tar: 1,024 examples per archive.motion_example_0801_dance_00751.tar: 491 examples.
Each example contains three files:
human_motion/<original_shard>/<name>.pt
motion_caption/<original_shard>/<name>.json
rendered_videos/<original_shard>/<name>.mp4
The first archive also contains:
metadata.jsonl
metadata_caption.jsonl
metadata_classification.jsonl
metadata_objects.jsonl
metadata_render.jsonl
Each metadata file has 291,952 rows in matching sample order. Paths are relative to
the extracted dataset directory. Original IDs range from 00477563 to 00769514;
they have not been renumbered.
video_path remains empty. Stickman videos are referenced by rendering_path
in metadata_render.jsonl; they are visualizations of the SMPL motion.
video_caption in metadata_caption.jsonl contains the previously composed,
gender-neutral descriptions of the two source clips, using one of eight transition
templates. The captions and motion segment JSON files are unchanged from the full dataset.
Verification and extraction
archive_index.tsv lists the archive names and example counts. SHA256SUMS contains
the SHA256 checksum for each tar archive. After downloading all archives:
sha256sum -c SHA256SUMS
mkdir -p motion_example_0801_dance
for archive in motion_example_0801_dance_*.tar; do
tar -xf "$archive" -C motion_example_0801_dance
done
The archives contain the three data directories and the five metadata files listed above.
