## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

## Bilibili Transcript Scraper — AI Speech-to-Text for B站 Videos

Turn any **Bilibili (B站) video into text** with real AI speech recognition.
Paste video links, get back the **full spoken transcript plus timestamped
sentences** as clean JSON — with **best-in-class Mandarin Chinese accuracy**,
ready for LLMs, RAG pipelines, content research, and subtitle workflows.

> **This is real ASR, not subtitle scraping.** Most "transcript" tools only
> download subtitles a creator happened to upload — and the majority of
> Bilibili videos have none. This Actor runs industrial speech recognition on
> the video's audio track, so it works on **any Bilibili video with speech**,
> subtitles or not. Chinese (Mandarin) recognition is its strongest language.

> **Unofficial.** This Actor is not affiliated with, authorized, or endorsed by
> Bilibili. It is an independent tool that processes publicly available
> content. Use it in compliance with Bilibili's terms and all applicable laws;
> you are responsible for how you use the retrieved data.

### What you get per video

- **Full transcript** (`fullText`) — the complete spoken content as one string.
- **Timestamped sentences** (`sentences[]`) — each with `startMs` / `endMs`,
  ready for subtitles, deep links, and clip selection.
- **Video metadata** — title, UP主 (author), duration, publish time, view /
  like / coin / favorite / danmaku / comment / share counts, and cover image
  URL, so every transcript arrives with its engagement context attached.

### Quick start

1. Open the Actor and press **Run** — the default input works out of the box.
2. Replace the example with your own video links: full URLs
   (`https://www.bilibili.com/video/BV…`), short share links
   (`https://b23.tv/XXXX`), or bare BV ids.
3. Language defaults to **Chinese**; switch to Auto for mixed or non-Chinese
   content.
4. Collect results from the **Dataset** tab as JSON / CSV / Excel, or pull them
   via the [Apify API](https://docs.apify.com/api/v2) and MCP from your own code.

No proxies, no cookies, no login — everything runs server-side.

### Example output

```json
{
  "videoId": "BV1HjmrBzEDA",
  "videoUrl": "https://www.bilibili.com/video/BV1HjmrBzEDA/",
  "title": "Ultra级旗舰!OPPO Find X9 Pro好用到超标 #数码生活 #科技数码",
  "author": "科技小辛",
  "durationSec": 87,
  "viewCount": 152000,
  "likeCount": 8400,
  "coinCount": 1200,
  "danmakuCount": 430,
  "language": "zh",
  "detectedSpeech": true,
  "sentenceCount": 13,
  "fullText": "如果有一台手机能让果粉变墨粉，那一定是OPPO Find X9 Pro…",
  "sentences": [
    { "text": "如果有一台手机能让果粉变墨粉，", "startMs": 280, "endMs": 2350 },
    { "text": "那一定是OPPO Find X9 Pro。", "startMs": 2350, "endMs": 4400 }
  ]
}
````

### What people build with it

- **Chinese-market research** — index what B站 UP主 actually *say* (not just
  titles) to understand trends, opinions, and product sentiment in your category.
- **Long-form knowledge mining** — Bilibili is China's home of tech reviews,
  tutorials, and video essays; transcripts turn hours of video into searchable,
  quotable text.
- **Viral-hook mining** — pull transcripts of the top videos in your niche and
  study the exact opening lines and structures that earn views and coins.
- **Cross-border content** — transcribe Chinese videos, then translate and
  repurpose them for YouTube or your own market.
- **LLM & RAG pipelines** — build Chinese-language corpora from real video
  speech, with engagement scores as a free quality signal.
- **Subtitles & translation** — timestamped sentences drop straight into
  SRT/VTT generation and dubbing workflows.

### Pricing & billing

Pay per started transcript minute (**$0.025/minute**, one-minute minimum).
Failed fetches, deleted or region-locked videos, videos over your duration cap,
and failed transcriptions are **not charged**.

### Why this Actor

- **Best-in-class Chinese ASR** — Mandarin recognition is its strongest
  language, where Western transcript tools struggle most.
- **Works without subtitles** — real speech recognition on the audio track;
  most Bilibili videos carry no CC subtitles to scrape.
- **Audio-only downloads** — Bilibili serves audio as a separate stream, so the
  Actor fetches megabytes instead of the full video. Long videos transcribe
  fast and cheap.
- **Engagement context included** — every transcript ships with view / like /
  coin / favorite / danmaku counts, so you can rank by performance immediately.
- **Direct API, no headless browser** — fast, stable runs with nothing to babysit.
- **No login, no cookies** — we never touch your accounts, so there's no ban risk.
- **Structured JSON** — export to CSV, Excel, or JSON, or pull straight from
  the API / MCP.

### Tips for better results

- Feed it the winners: find the top-performing videos in your niche first
  (search / channel scrapers), then transcribe just those.
- Keep the language on **Chinese** for B站 content — it noticeably improves
  accuracy over Auto.
- The default duration cap is 60 minutes; raise `maxDurationMinutes` (up to
  240\) for lectures and documentaries, or lower it to keep batch runs snappy.
- For multi-part videos (分P), part 1 is transcribed; submit other parts'
  direct URLs if you need them.
- `detectedSpeech: false` flags music-only / no-speech videos so you can filter
  them out downstream.

### FAQ

**Do I need an account, cookies, or to log in anywhere?**
No. The Actor talks to fast, direct HTTP APIs server-side — you just provide
video links and run it.

**Does it work on videos without subtitles?**
Yes — that's the point. It runs real speech recognition on the audio, so
subtitles are never required (and most Bilibili videos don't have them).

**How good is the Chinese accuracy?**
Mandarin is the model's strongest language; it handles fast colloquial speech,
regional accents, and technical vocabulary well, and returns punctuated
sentences.

**What about really long videos?**
Videos longer than your `maxDurationMinutes` cap (default 60) are skipped and
not charged. Raise the cap up to 240 minutes when you need lectures or
documentaries — audio-only downloads keep even those runs quick.

**How am I billed?**
$0.025 per started transcript minute. Videos that can't be fetched or
transcribed are not charged.

**Can I run it on a schedule or call it from my app?**
Yes — use Apify Schedules, the REST API, the JavaScript / Python clients, or
the MCP server. See the **API** tab.

**Is this affiliated with Bilibili?**
No. It's an independent tool that processes publicly available content. Use it
in line with the platform's terms and applicable law.

# Actor input Schema

## `videoUrls` (type: `array`):

Bilibili video links to transcribe. Accepts full URLs (`https://www.bilibili.com/video/BV…`), short share links (`https://b23.tv/XXXX`), or bare BV ids. One transcript is produced per video (part 1 for multi-part videos).

## `language` (type: `string`):

Language spoken in the videos. Defaults to Chinese (B站 is Mandarin-heavy and Chinese accuracy is best-in-class). Choose Cantonese for 粤语 content, or Auto for mixed / non-Chinese audio.

## `maxDurationMinutes` (type: `integer`):

Videos longer than this are skipped (and not charged). Bilibili hosts multi-hour videos; the default keeps runs fast and predictable. Raise it up to 240 for long lectures or documentaries.

## `proxyConfiguration` (type: `object`):

Optional. Route the upstream API calls through an Apify Proxy to vary the source IP. Usually not needed.

## Actor input object example

```json
{
  "videoUrls": [
    "https://www.bilibili.com/video/BV1HjmrBzEDA/"
  ],
  "language": "zh",
  "maxDurationMinutes": 60,
  "proxyConfiguration": {
