| # 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 |
| ``` |
|
|
| Several large archives are distributed as multi-part files to satisfy Hub file-size limits. `unpack_data.sh` detects these parts automatically and streams them into a single extraction pass. |
|
|
| ### 2. Extract frames |
|
|
| To extract frames only for one or more selected benchmark JSON files: |
|
|
| ```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 |
| ``` |
|
|
| This decodes only the episodes referenced by the provided benchmark JSON file(s), rather than scanning the full raw-data release. |
|
|
| If `--benchmark-json` is omitted, the extractor scans all benchmark JSON files under `benchmark_style_all/`, collects all referenced records, and extracts the corresponding `main_path` videos: |
|
|
| ```bash |
| python scripts/extract_vlac2_release_frames.py \ |
| --data-root /path/to/data \ |
| --frames-root /path/to/data_extracted_frames |
| ``` |
|
|
| ### 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. |
| * `annotation_files_raw/` mirrors the original raw annotation JSON tree used during benchmark construction. |
| * 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. |
| * The large raw-data archives are distributed as split `.part-*` files in `data/`; these are unpacked transparently by the provided script. |
