# BABEL Official Local Layout

This directory is a cleaned local mirror of the official BABEL v1.0 labels and
the AMASS subsets required by those labels.

## Layout

- `archives/`: original downloaded archives, kept unchanged for provenance.
- `labels/babel_v1.0_release/`: official BABEL JSON splits.
- `amass/`: extracted AMASS motion parameter files.
- `processed/manifests/*.jsonl`: normalized records with resolved local AMASS
  paths, frame counts, fps, segment labels, and rewritten captions.
- `processed/viewer_index.json`: compact index consumed by the SMPL mesh viewer.
- `processed/validation_summary.json`: extraction and coverage validation report.
- `extract_logs/`: per-archive extraction logs.

## Viewer

Run:

```bash
python3 motion_annot_web/babel_official_mesh_viewer/app.py --host 0.0.0.0 --port 18777
```

The viewer lazily converts selected AMASS clips into SMPL mesh vertex caches
under `motion_annot_web/babel_official_mesh_viewer/data/`.

## HuggingFace Upload

This is licensed BABEL/AMASS data. Upload it only to a private or gated
HuggingFace dataset repository that is consistent with the upstream licenses.
The intended upload contents are `labels/`, `amass/`, `processed/`, this README,
and `extract_logs/`; uploading the original archives as well is redundant.
