+# VLAC-Cut-FullData
+
+VLAC-Cut-FullData is the full-data release for VLAC-Cut. It provides the complete raw-data archive set, benchmark-style JSON files, and a lightweight frame-extraction workflow for reproducing evaluation on the released benchmark protocol.

+```
+
+## Usage
+
+### 1. Unpack the raw-data archives
+
+```bash
+bash scripts/unpack_data.sh /path/to/data
+```
+
+### 2. Extract frames for a selected benchmark JSON
+
+```bash
+python scripts/extract_vlac2_release_frames.py \
+  --data-root /path/to/data \
+  --frames-root /path/to/data_extracted_frames \
+  --benchmark-json benchmark_style_all/test_expert_seen/video_progress_benchmark_file.json
+```
+
+The frame extractor decodes only the episodes referenced by the provided benchmark JSON file(s), rather than scanning the full raw-data release.
+
+### 3. Use the benchmark JSON files
+
+Frame paths in the benchmark JSON files use the prefix:
+
+```text
+__VLAC2_FRAMES_ROOT__/
+```
+
+Replace `__VLAC2_FRAMES_ROOT__` with the absolute path to the extracted-frame directory.
+
+## Notes
+
+* This release contains the complete raw-data archive set used by the VLAC-Cut benchmark release workflow.
+* The `benchmark_style_all/all` split is larger than the benchmark evaluation subsets and is rebuilt from the full annotation PKL source tree.
+* The benchmark JSON files are pre-generated and do not need to be rebuilt for standard use.
