# LAION-BVD — RAW Corpus File Index

This repository is the **file index of the LAION-BVD raw corpus**: one row for every object stored for the ~80M downloaded videos (video, audio, metadata, subtitles, comments). It contains **no media** — only object keys and sizes.

The index is the manifest used to fetch the raw files themselves. Access is granted to researchers on request (see [Requesting access](#requesting-access)), after which the keys in this index can be resolved against the object storage.

## Requesting access

This index itself is public, but the raw media it points to is not. Access to the raw
corpus (and to all gated LAION-BVD subsets) is granted through a single, central
access request that you only need to submit once:

**➡️ [LAION-BVD access request form](https://forms.gle/5tXPS4gmBwSGYYbV8)**

Access is restricted to academic and non-commercial research. Requests are reviewed
manually on a rolling basis. Once access is granted, the keys in this index can be
resolved against the object storage — see
[the BVD-RAW access guide](https://projects.laion.ai/bvd/bvd-raw-access.html) for the
transfer manifest format and delivery steps.

## Dataset structure

| Column | Type | Description |
|---|---|---|
| `key` | string | Object key, `<id>/<id>.<ext>` |
| `size` | int64 | Object size in bytes |
| `id` | string | Video ID (e.g. YouTube ID); the `_comments` suffix is stripped so all files of a video share one `id` |
| `ext` | string | Everything after the first dot of the filename, e.g. `mp4`, `info.json` |

Rows are sorted by `key`, and all objects belonging to one video are guaranteed to live in the same shard — a single shard can be processed independently without losing files of a video across a shard boundary.

## Relation to LAION-BVD

| Release | Description |
|---|---|
| [laion/BVD-URLs](https://huggingface.co/datasets/laion/BVD-URLs) | 1.3B video URLs extracted from CommonCrawl |
| **laion/BVD-RAW-Index** — this dataset | File index of the ~80M downloaded raw videos (media by request) |
| [laion/BVD-V-55M](https://huggingface.co/datasets/laion/BVD-V-55M) / [-URLs](https://huggingface.co/datasets/laion/BVD-V-55M-URLs) | 55M scene-level video clips with captions and timestamps |
| [laion/BVD-A-10M](https://huggingface.co/datasets/laion/BVD-A-10M) / [-URLs](https://huggingface.co/datasets/laion/BVD-A-10M-URLs) | 10M audio clips randomly sampled from BVD-V-55M |
| [laion/BVD-A-1.7M](https://huggingface.co/datasets/laion/BVD-A-1.7M) / [-URLs](https://huggingface.co/datasets/laion/BVD-A-1.7M-URLs) | 1.7M audio clips from BVD-V-55M with unique source videos |

BVD-RAW itself — the raw pool of 80M videos totalling 10M hours — is not distributed through
Hugging Face. The gated subsets and BVD-RAW are available to academic and non-commercial
researchers through a single central [access request form](https://forms.gle/5tXPS4gmBwSGYYbV8); the
[BVD-RAW access guide](https://projects.laion.ai/bvd/bvd-raw-access.html) describes the raw-corpus transfer procedure.
