Download Bilibili videos with danmaku bullet comments in MP4 up to 2160p, using the BV number to fetch any public video without login.
Every video on Bilibili is uniquely identified by a BV number (or, for older content, an av number). You’ll see it in the URL after bilibili.com/video/ or in the page source. When you paste that URL into the downloader, the tool extracts the BV number to locate the raw media files—even for videos that require premium membership or are geo-restricted. Because Bilibili does not apply DRM to the vast majority of its catalog, the downloader can directly grab the highest quality stream, up to 2160p (4K), in MP4 or HLS format. Just copy the URL, and the BV number does the rest.
Bilibili serves video in several codecs (H.264, H.265, AV1) and container formats. The downloader automatically selects the most efficient stream available, but you can manually choose from:
Bilibili offers multiple quality levels, not all of which are available for every video. Typical options include:
Some videos also support HDR or Hi-Res audio (e.g., from Bilibili Music). The downloader lists every quality variant found in the manifest, so you can pick the one that matches your storage and viewing needs.
Bilibili is more than user‑uploaded videos. The platform includes several sub‑products that the downloader can handle:
Danmaku (commentary overlays) are a hallmark of Bilibili. The downloader does not inject danmaku into the saved file, but you can optionally download the danmaku XML file alongside the video—useful for archiving or re-syncing in a player that supports ASS subtitles.
Bilibili does not require an account to view most content, but some high‑quality streams (especially 1080p+ or premium‑exclusive videos) are locked behind premium membership (called "大会员"). The downloader respects these restrictions: if a stream requires a logged‑in premium account, you must supply your cookies or token. Similarly, certain region‑locked content (e.g., anime licensed only for China) will fail unless you use a proxy or VPN. The tool will clearly indicate when a stream is blocked.
By understanding these platform‑specific details, you can reliably save Bilibili content at its original quality—danmaku, BV numbers, and all.
