## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## YouTube AI Translator — translated subtitles for any video

Gemini AI **watches the actual video** and translates every spoken word into your language — producing ready-to-use **translated SRT and WebVTT subtitle files**, JSON segments, and plain text. It works on videos with **no captions at all**, from any spoken language.

Caption translators need existing captions. This actor listens to the video itself.

### What it does

- ✅ Translates speech from **any language into any language** — directly from the video's audio
- ✅ Works on videos **without captions**
- ✅ **Translated SRT/VTT subtitle files** ready for video players and editors
- ✅ **Speaker labels** and **timestamps** on every segment
- ✅ Detects and reports the original language
- ✅ No API key needed — or bring your own Gemini key and pay 5× less

### Pricing

Charged **per minute of video** (minimum 5 minutes per video), plus a $0.02 actor start fee.

| Video length | No API key (bundled) | With your Gemini key |
|---|---|---|
| Short (≤5 min) | $0.75 | $0.15 |
| 10 min | $1.50 | $0.30 |
| 30 min | $4.50 | $0.90 |
| 60 min | $9.00 | $1.80 |

**Bring your own key and save 5×**: create a free key at [aistudio.google.com/apikey](https://aistudio.google.com/apikey) and paste it into the `geminiApiKey` field (stored encrypted, used only for your run). Google token costs (a few cents per hour of video) are then billed to your Google account.

You are only charged when a translation is actually delivered — failed or timed-out runs charge nothing beyond the start fee.

### Input

| Field | Type | Description |
|---|---|---|
| `videoUrl` | string (required) | Public YouTube video URL (watch, youtu.be, or Shorts link) |
| `targetLanguage` | string (required) | Language to translate into, e.g. `"English"`, `"Spanish"`, `"Japanese"` |
| `includeSpeakers` | boolean | Label each segment with the speaker (default `true`) |
| `outputFormats` | array | Any of `json`, `srt`, `vtt`, `text` (default: all) |
| `model` | string | `gemini-3.7-flash` (default) or `gemini-3.5-flash-lite` |
| `geminiApiKey` | secret string | Optional — your Google AI Studio key for 5× cheaper runs |

### Output

One dataset item per run:

```json
{
  "videoUrl": "https://www.youtube.com/watch?v=…",
  "videoTitle": "…",
  "durationSeconds": 600,
  "minutesCharged": 10,
  "originalLanguage": "Japanese",
  "targetLanguage": "English",
  "segmentCount": 84,
  "translation": "[00:01] Speaker 1: Welcome to the show...",
  "segments": [
    { "start": "00:01", "end": "00:05", "speaker": "Speaker 1", "text": "Welcome to the show." }
  ],
  "srtUrl": "https://api.apify.com/v2/key-value-stores/…/records/translation-….srt",
  "vttUrl": "…", "jsonUrl": "…", "textUrl": "…",
  "status": "completed"
}
```

The translated SRT/VTT/JSON/text files are saved to the run's key-value store with public download URLs — drop the SRT straight into a video editor or player.

### Use it via API

```bash
curl -X POST "https://api.apify.com/v2/acts/andok~youtube-ai-translator/run-sync-get-dataset-items?token=$APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"videoUrl": "https://www.youtube.com/watch?v=…", "targetLanguage": "English"}'
```

### FAQ

**How is this different from translating captions?** Caption translation needs captions to exist and inherits their errors. This actor has Gemini listen to the actual audio and translate what is really said — with speaker labels and visual context.

**What videos are supported?** Public, finished YouTube videos up to 120 minutes (150 minutes with your own key). Private, unlisted, and live videos are not supported.

**What language pairs?** Any-to-any among the languages Gemini understands — including Estonian, Japanese, Arabic, Hindi, and ~100 more.

**What if the run fails?** You are never charged per-minute fees for a failed or undelivered translation.

# Actor input Schema

## `videoUrl` (type: `string`):

Public YouTube video to translate (youtube.com/watch, youtu.be, or Shorts link). Private and unlisted videos are not supported.

## `targetLanguage` (type: `string`):

Language to translate the speech into, e.g. "English", "Spanish", "Estonian", "Japanese".

## `includeSpeakers` (type: `boolean`):

Label each segment with the speaker (real names when identifiable, otherwise Speaker 1, Speaker 2, …).

## `outputFormats` (type: `array`):

Translated subtitle/transcript files saved to the run's key-value store, each with a public download URL in the results.

## `model` (type: `string`):

Bundled-key runs allow gemini-3.7-flash and gemini-3.5-flash-lite. The other models require your own geminiApiKey.

## `geminiApiKey` (type: `string`):

Bring your own Google AI Studio key (aistudio.google.com/apikey) and pay only $0.03 per video minute instead of $0.15; Google token costs are then billed to your Google account. Leave empty to use the bundled key.

## CLI example

```bash
echo '{
  "videoUrl": "https://www.youtube.com/watch?v=jNQXAC9IVRw",
  "targetLanguage": "English"
}' |
apify call andok/youtube-ai-translator --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,andok/youtube-ai-translator"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
