Can I transcribe a specific part from a multi-part video?

Yes. When you paste a Bilibili link for a multi-part video, you can select which part (P1, P2, P3, etc.) to transcribe. You don't have to process the entire series.

How accurate is it for Cantonese or Sichuan dialect?

Vocova handles major Chinese dialects well, including Cantonese and Sichuan dialect. Accuracy is highest for clear speech in standard dialects. Heavy code-switching between dialects within a single sentence may reduce accuracy slightly.

Are danmaku (scrolling comments) included in the transcript?

No. Danmaku are viewer-generated text overlays, not spoken audio. Vocova transcribes only the video's audio track. Danmaku, on-screen annotations, and subtitle overlays are not captured.

Do both BV and AV URLs work?

Yes. Paste either the modern BV-format URL (bilibili.com/video/BV...) or the legacy AV-format URL (bilibili.com/video/av...). Both are automatically recognized.

Can it handle very long educational videos?

Yes. Many Bilibili educational videos run 1–2 hours. Vocova processes full-length videos without truncation, maintaining accuracy throughout.

Does it work with login-required or member-only videos?

No. Vocova can only access publicly available Bilibili videos. Member-exclusive content and login-restricted videos cannot be processed.

What about Japanese or English content on Bilibili?

Vocova supports 100+ languages with automatic detection. Japanese anime, English tutorials, and other non-Chinese content on Bilibili is transcribed just as accurately.

Features

Multi-part video support

Bilibili's P1/P2/P3 multi-part format is unique to the platform. Select a specific part to transcribe, so you get exactly the section you need without processing the entire series.

Chinese dialect handling

Bilibili content spans Mandarin, Cantonese, Sichuan dialect, and other regional varieties. Vocova detects and transcribes each dialect accurately, not just standard Mandarin.

Academic content density

Bilibili is a hub for educational content — university lectures, technical tutorials, and science explainers. Vocova handles the specialized vocabulary and dense information delivery common in these videos.

BV and AV URL formats

Whether you copy a modern BV-format URL or an older AV-format link, both are recognized and processed. Just paste whatever URL your browser shows.

100+ languages beyond Chinese

Bilibili hosts international content too. Japanese, English, Korean, and other languages are auto-detected and transcribed alongside Chinese-language videos.

Why choose Vocova

Turn educational videos into study notes

Bilibili's educational content is some of the best on the internet. Convert lectures and tutorials into text you can annotate, highlight, and review.

Search within video content

Video audio is unsearchable. With a transcript, you can instantly find specific explanations, formulas, or references across hours of educational content.

Create subtitles for cross-platform sharing

Export SRT or VTT files to add subtitles when sharing Bilibili content on other platforms, improving accessibility and reach.

Preserve dialect content in text

Regional dialect content on Bilibili captures cultural perspectives that standard Mandarin doesn't. Transcripts preserve this spoken content in a referenceable format.
