+
+```python
+from datasets import load_dataset
+from huggingface_hub import hf_hub_download
+
+index = load_dataset("eyesjapan/eyesjapan-mocap", split="train")
+walks = index.filter(lambda x: x["category"] == "walk" and "bvh" in x["formats"])
+
+path = hf_hub_download(
+    repo_id="eyesjapan/eyesjapan-mocap", repo_type="dataset",
+    filename="data/free/accident/free-accident-dodge-azumi/00004-free-accident-dodge-azumi.bvh",
+)
+```
+
+## Data collection & consent
+
+<!-- TODO: capture hardware/software, studio, subject recruitment. Reference
+videos show identifiable performers — confirm all subjects consented to public
+research release, or exclude the .mov/.m4v files. -->
