Get a Bilibili transcript
Paste a Bilibili URL above and the spoken audio comes back as timestamped text. Bilibili is the platform where "this video has subtitles" is least likely to mean "this video has a subtitle file": a meaningful share of its content — fan-subbed and reposted material above all — has the text burned into the video image, and real closed captions are inconsistent, especially for non-Mandarin audio.
It's also worth being explicit that danmaku is not a caption track. The scrolling comment overlay Bilibili is known for is viewer commentary, not the video's spoken content, so scraping it gives you an audience reaction rather than a transcript. Transcribing the audio is usually the only way to get machine-readable text out of a Bilibili video, including ones that visibly appear to have subtitles.
- Handles the platform's long-form skew — lectures, commentary and review content well past 10 minutes.
- Works on videos whose subtitles are burned into the image, where there is no file to extract.
- Transcribes the audio in its source language; it does not translate the video.
- JSON export keeps segment timings if you're indexing a backlog rather than reading one video.
Captions on Bilibili, as they actually are
Real closed captions are inconsistent, especially for non-Mandarin audio. Bilibili's signature "danmaku" — the scrolling comment overlay — is not a caption track; it's viewer commentary and doesn't contain the video's actual spoken content. A meaningful share of the platform's video (especially fan-subbed or reposted content) has subtitles hardcoded into the image instead of stored as a separate file.
- Typical length
- Skews long-form relative to TikTok/Instagram — lectures, documentary commentary, and long-form review content are common, often 10+ minutes.
- URL shape
- bilibili.com/video/BV...
