| # VCDB Core Audio Retrieval |
|
|
| This repository packages audio extracted from the **528-video core set** of |
| VCDB as a symmetric audio-to-audio retrieval task for MTEB/MOEB. The separate |
| 100,000-video background collection is not included. |
|
|
| ## Terms and provenance |
|
|
| The source dataset is provided by Fudan University for **research purposes |
| only**. The source authors and Fudan University make no warranties about the |
| dataset, including non-infringement. Users must review and follow the |
| [original VCDB terms](https://web.archive.org/web/20251123150707/https://fvl.fudan.edu.cn/dataset/vcdb/list.htm). The original page is |
| [`https://fvl.fudan.edu.cn/dataset/vcdb/list.htm`](https://fvl.fudan.edu.cn/dataset/vcdb/list.htm) and may be intermittently unavailable. |
|
|
| The source videos were collected from YouTube and MetaCafe. Rights in the |
| underlying media remain with their respective rightsholders. This packaging |
| does not grant additional rights beyond the source terms. |
|
|
| ## Construction |
|
|
| - Raw core videos: 528 |
| - Videos with an audio stream: 527 |
| - Unique packaged audio files (SHA-256): 461 |
| - Videos without an audio stream: 1 |
| - Audio queries: 527 |
| - Unique undirected relevant pairs: 5584 |
| - Directed binary qrels: 11168 |
|
|
| Stable IDs remain the original topic-relative video paths. The source video |
| without audio, `maradona_hand_of_god/de71afa5fe2363589c28021940d2902d8701efdf.flv`, is excluded. Qrels |
| involving it are removed, and every retained query has at least one positive. |
| The 66 repeated audio files belong to distinct source video IDs and are |
| retained as meaningful positives for copy detection. |
|
|
| Relevance is derived from VCDB's human segment-level video copy annotations: |
| multiple annotations for the same source-video pair are collapsed, and both |
| directions are emitted. These are not independent audio-copy judgments. |
|
|
| ## Audio extraction |
|
|
| Source codec counts: `{"aac": 512, "adpcm_swf": 13, "mp3": 2}`. |
| Packaged codec counts: `{"aac": 527}`. |
|
|
| AAC elementary streams are remuxed without re-encoding into `.m4a`. The |
| 15 non-AAC tracks are deterministically |
| encoded to AAC at 128 kb/s with one FFmpeg thread, with metadata and chapters |
| removed. Every packaged track is fully decoded during validation. |
|
|
| Re-encoded tracks: |

| ## Limitations |
|
|
| VCDB was designed for temporal partial-copy detection in video. Copied visual |
| segments may have modified or replaced sound, so audio-only relevance can be |
| noisy. This adaptation also uses only the core set and cannot reproduce the |
| paper's segment-level F1 score or complete 100K-background protocol. |
