+Each archive holds one task and extracts to:
+
+```
+G-11_handle_object_reappearance_data-generator/                     # task
+└── handle_object_reappearance_task/                                # subtask

+```
+
+Sample ids run `00000000`–`00004999`.
+
+All 250 archives share this shape and no two overlap, so they can be extracted
+into one directory.
+
+### Index files
+
+`meta_video_train.json` maps every task to its jsonl:
+
+```json
+{
+  "G-11_handle_object_reappearance_data-generator": {
+    "root": ".",
+    "annotation": "jsonl/G-11_handle_object_reappearance_data-generator.jsonl",
+    "length": 5000,
+    "task": "Video-SFT"
+  }
+}
+```
+
+`root` is the directory the archives were extracted into; `length` is that task's
+row count. Each jsonl row points at one sample, with every path relative to `root`:
+
+| Field | Meaning |
+|---|---|
+| `sample_id` | e.g. `handle_object_reappearance_00000000` |
+| `first_frame` | conditioning image |
+| `metadata` | that sample's `metadata.json` |
+| `clip_path` | reference video |
+| `final_frame` | last frame of the reference video |
+| `prompt` | instruction |
+
+## Usage
+
+```bash
+huggingface-cli download Video-Reason/VBVR-Pro-SFT-Image --repo-type dataset --local-dir data/VBVR-Pro-SFT-Image
+huggingface-cli download Video-Reason/VBVR-Pro-SFT-Video --repo-type dataset --local-dir data/VBVR-Pro-SFT-Video
+```
+
+The [VBVR-Pro training code](https://github.com/Video-Reason/VBVR-Pro) unpacks the
+archives and emits the per-trainer manifests in one step:
+
+```bash
+python training/prepare_data.py \
+  --image-archives data/VBVR-Pro-SFT-Image \
+  --video-archives data/VBVR-Pro-SFT-Video \
+  --output-dir data/prepared
+```
+
+To use the data directly instead, extract every archive into one directory and
+point `root` at it:
+
+```bash
+mkdir -p data/extracted
+for f in data/VBVR-Pro-SFT-Video/tars/*.tar.gz; do tar xzf "$f" -C data/extracted; done
+```
