Chinese Video Transcriber: Bilibili to Text, English & SRT

Chinese Video Transcriber turns Bilibili (B站 / 哔哩哔哩) videos, or any audio or video file link, into a timestamped transcript with AI, then translates it into English or 12 other languages. You get plain text, timestamped segments and ready-to-use SRT subtitles for both the original and the translation. Paste links; no login, no browser, no proxy setup.

Use it to read and quote Chinese videos without speaking Chinese, add subtitles, research Chinese creators and markets, feed transcripts to AI and RAG pipelines, or transcribe podcasts and lectures.

• 🎬 Bilibili links, b23.tv share links or BV IDs, plus any direct audio/video file URL (mp3, m4a, wav, ogg, mp4, webm …).
• 📝 Transcript with timestamps: one line per sentence, start and end in seconds, in the spoken language (Chinese in simplified characters).
• 🌍 Translation into English, Spanish, French, German, Portuguese, Russian, Japanese, Korean, Vietnamese, Thai, Indonesian, Arabic or Simplified Chinese, with the same timestamps.
• 🎞️ SRT subtitles for the transcript and for the translation.

Multi-part Bilibili videos are transcribed from their first part.

How much does it cost?

Pay per minute of audio. There is no monthly fee.

Event	Price (FREE/BRONZE)	Lower on paid plans
Transcript minute	$0.01 / started minute	down to $0.0085
Translation minute (optional)	$0.005 / started minute	down to $0.0045
Actor start	$0.00005 / run	—

A 10-minute video costs $0.10 to transcribe, or $0.15 with an English translation. Nothing is charged for a video that fails. Set Max minutes per video to cap the cost of very long videos (they're transcribed up to that length and marked truncated), and a maximum cost per run to cap the whole run.

Free plan: the AI runs on paid infrastructure, so free-plan runs include a 3-minute trial; upgrade to transcribe full videos.

 "translatedSrt": "1\n00:00:00,000 --> 00:00:02,500\nThe differences in news reporting across various regions of China.\n…"
}

A translation is saved only when every line was translated, so you never get a half-translated file. If translation fails, the transcript is still saved and only the transcript is charged.

FAQ

Do I need a Bilibili account or a proxy? No. Paste public links.

What happens with a deleted or private video? It's skipped with a clear message and not charged. A run where every link was invalid still succeeds, with "No results … Check the input".

Can I transcribe podcasts or my own files? Yes, if the file has a public http(s) link. Links to private or local network addresses are refused.

How are minutes counted? Per started minute of audio actually transcribed, so a 61-second clip is 2 minutes.

Is this an official Bilibili product? No. This is an independent tool and is not affiliated with or endorsed by Bilibili.

Is it legal? It processes publicly available media. You are responsible for how you use the transcripts and for respecting copyright and the platforms' terms.
