| # RA-Bench-Extended
|
|
|
| RA-Bench-Extended is the expanded media and reproducibility archive associated
|
| with **RA-Bench**, a benchmark for AI-generated video detection that uses real
|
| videos as anchors.
|
|
|
| The original [`RA-Bench`](https://huggingface.co/datasets/liangshuo0111/RA-Bench)
|
| repository remains the frozen paper benchmark. This repository adds generation
|
| variants that are useful for controlled analysis but are not part of the main
|
| benchmark average.
|
|
|
| ## Node archive scope |
|
|
| The first release phase contains:
|
|
|
| - the frozen RA-Bench main media;
|
| - RA-Bench-HumanProof indices, which reference media in the main split rather
|
| than duplicating files;
|
| - RA-Bench-LastMile media;
|
| - seeds 0, 42, and 123 for Wan2.2 dynamic, Wan2.2-Lightning, LTX, and
|
| OmniWeaving;
|
| - seeds 0, 42, and 123 for the auxiliary fixed-duration Wan2.2 control. |
|
|
| The canonical node07/node09 archive contains 46,266 unique media entries. |
| Of these, 45,555 are redistributable media files and 711 are retained only as |
| local provenance because their licenses do not permit direct redistribution. |
|
|
| | Component | Canonical media | Public media | URL/private provenance | |
| |---|---:|---:|---:| |
| | RA-Bench main | 17,886 | 17,375 | 511 | |
| | Additional all-seed/control media | 20,130 | 20,130 | 0 | |
| | RA-Bench-LastMile T1--T5 | 8,250 | 8,050 | 200 | |
| | **Total** | **46,266** | **45,555** | **711** | |
|
|
| RA-Bench main contains 1,830 real anchors and 16,056 generated videos: |
|
|
| | Source | Family | Videos | |
| |---|---|---:| |
| | Real anchors | Real | 1,830 | |
| | Wan2.2 dynamic | Open-source | 1,830 | |
| | Wan2.2-Lightning | Open-source | 1,830 | |
| | LTX | Open-source | 1,830 | |
| | OmniWeaving | Open-source | 1,830 | |
| | HappyHorse | Closed-source | 1,787 | |
| | Runway | Closed-source | 1,805 | |
| | Kling v3 | Closed-source | 1,790 | |
| | Hailuo 2.3 Fast | Closed-source | 1,830 | |
| | Seedance2.0 | Closed-source | 1,524 | |
|
|
| The complete first-frame I2V seed pool contains 1,830 videos for every |
| source--seed cell. It covers Wan2.2 dynamic, Wan2.2-Lightning, LTX, |
| OmniWeaving, and the fixed-duration Wan2.2 control at seeds 0, 42, and 123. |
| The four main generators' seed-0 videos already appear in `media/main/`, so |
| `media/all_seeds/` contributes 20,130 additional files without duplication. |
|
|
| RA-Bench-LastMile contains 1,650 transformed videos at each dissemination |
| stage T1--T5, for 8,250 canonical transformed videos. T0 refers to the |
| corresponding canonical main/control media and is not duplicated. |
|
|
| Media that cannot be redistributed is not uploaded. Its metadata remains in the |
| rights-aware release tables so that users can reconstruct eligible real anchors |
| from their original URLs. The public archive contains no reviewer credentials, |
| authentication material, or private review records. |
|
|
| RA-Bench-HumanProof consists of 633 indices into RA-Bench main. It adds no |
| duplicate media; its membership is provided in |
| `metadata/ra_bench_humanproof.{csv,jsonl}`. |
|
|
| The later HKUST phase will add the controlled T2V and first+last-frame I2V
|
| generation settings after a separate inventory and validation pass.

|
|
| ## Download and verification |
|
|
| Install `huggingface_hub`, then download either the full public archive or one |
| component: |
|
|
| ```bash |
| python tools/download_rabench_extended.py \ |
| --local-dir /path/to/RA-Bench-Extended \ |
| --component all |
| ``` |
|
|
| After downloading, verify every media file against the public size index: |
|
|
| ```bash |
| python tools/verify_media_index.py /path/to/RA-Bench-Extended |
| ``` |
|
|
| ## Release status |
|
|
| The node07/node09 phase is complete. The public repository contains exactly |
| 45,555 media files totaling 186,004,326,480 bytes. Repository paths and file |
| sizes match the frozen public index with zero missing, extra, or mismatched |
| files, and every media object has a published SHA-256 checksum. The checksum |
| table is available under `metadata/public_media_checksums.csv`. |
|
|
| The controlled HKUST T2V and first+last-frame I2V phase remains pending and is |
| not included in these frozen counts. |
