Why Archive Bilibili Videos with Ai2Done?
Bilibili (B站) is the gold standard for long-form Chinese technical content: anime fan-dubs (鬼畜), university lecture replays, GDC-style conference talks in Chinese, game tutorials with on-screen barrage comments (弹幕), maker-DIY series, and STEM education channels that rival YouTube in production value. The user base of a Bilibili downloader is dominated by researchers and educators, not casual viewers: a Mandarin language teacher wants a tagged MP4 of a 国创 animation for classroom analysis; a competitive intelligence analyst needs a stable copy of a Chinese game developer's behind-the-scenes talk before the channel pivots; a Chinese-diaspora educator outside the Great Firewall wants offline access because B站 throttles non-mainland IPs. Ai2Done's Bilibili downloader supports the canonical bilibili.com/video/BV<id>/ URL format (the new BVID system that replaced the older AV<number> URLs), plus b23.tv short links from the app share sheet. Multi-part videos (multi-P, e.g. a 10-episode lecture series uploaded as one post) are detected and you can download a single P or all parts. Two important platform constraints: (1) 番剧 (licensed anime/dramas) and 大会员 (premium subscription) content cannot be downloaded — those are DRM-protected. (2) Videos taller than 1080p (4K, 8K HDR) are typically encoded in AVC/HEVC and may require a B站 大会员 to even play in the highest tier; we'll deliver the best non-DRM tier available, which is usually 1080p for non-members.
How to download a Bilibili video (UGC or multi-P)
- Copy the video URL from bilibili.com (looks like bilibili.com/video/BV1xx411x7xx/) or use the app share sheet to get a b23.tv short link. Both are accepted. For multi-P videos, you can append `?p=N` to target a specific part, or omit it to see the full part list.
- Paste the link. The preview lists every available quality tier (360p / 480p / 720p / 1080p / 1080p+) and, for multi-P posts, every episode (P1, P2, …). Note: 1080p+ / 4K / 8K tiers may be greyed out — those require a 大会员 session that the tool does not provide.
- Select the part(s) and quality (1080p MP4 is the default for non-members), then click Download. For multi-P series, parts download sequentially into a ZIP named `bilibili_{BVID}_{title}.zip` so episode order is preserved.
