| # BenchCheck / Sextant — data archive (research use only) |
|
|
| Companion data for [github.com/Espere-1119-Song/BenchCheck](https://github.com/Espere-1119-Song/BenchCheck) |
| (video-benchmark meta-evaluation, archive freeze 2026-08-24). Restore guide: `HANDOFF.md` in the GitHub repo. |
|
|
| **Research use only.** `normalized/` mirrors video clips from 189 upstream video |
| benchmarks — most were publicly released by their authors; a subset was re-fetched |
| from YouTube following the benchmarks' official video-ID lists — normalized to ≤480p |
| for evaluation reproducibility. All rights remain with the original content owners |
| and benchmark authors; this mirror exists solely to make the accompanying |
| meta-evaluation reproducible. Do not redistribute outside research use. |
| **Takedown**: content owners or benchmark authors may open a discussion on this repo |
| and the affected files will be removed promptly. |
|
|
| ## Layout: loose files + tar volumes |
|
|
| Due to per-file commit limits, most videos ship as tar volumes: |
|
|
| - `normalized/…` — files committed individually before the switch. |
| - `normalized_tars/normalized_part_XX.tar` — the remaining ~135GB; member paths are |
| relative (`normalized/<hash>/<file>`), so extraction merges into the same tree. |
| - `normalized_tars/tar_manifest.csv` — `volume,path` for every packed file. |
|
|
| Restore the full tree (run at the download root; duplicates are identical, tar wins): |
|
|
| ```bash |
| for t in normalized_tars/normalized_part_*.tar; do tar xf "$t"; done |
| ``` |
|
|
| ## Contents |
|
|
| | path | size | what | |
| |---|---|---| |
| | `sextant_data_bundle.tar.gz` | 472MB | `exp/data/` sans frames: SigLIP-2/DINOv3/text embeddings, captions, P1 full per-question results (303,297 rows), per-bench samples (n=300, seed=42), manifests, n0 caches; + `exp/watch/logs/` (classifier audit trail) | |
| | `sextant_archive104.tar.gz` | ~5.5GB | rescue of GPU-node store: `annotations/` (raw benchmark annotation files), `p1_raw/`, `samples/` + `samples_av_excluded/` + `samples_dropped/` + fix backups, `results_local/`, `logs/` (manifest/failures/dedup), 104-side code mirror, `conditions_results.csv` | |
| | `normalized/` | 136GB | 27,233 normalized videos (stage-C output; filenames = `<bench>__<safe qid/video id>`), the expensive-to-rebuild asset (YouTube portions need fresh cookies) | |
|
|
| ## Rebuild notes |
|
|
| - Frame caches (77GB local + 32GB node) were intentionally dropped: rebuild with |
| `exp/pipeline/extract_frames.py` from `normalized/`. |
| - Zip/tar index caches were dropped: auto-rebuilt on first access. |
| - Everything else (all result tables) lives in the GitHub repo under `exp/results/`. |
