# Generate SRT subtitles from a video or audio URL

**Use case:** 

Give a direct media URL and get broadcast-shaped captions back: SRT and VTT with cues split at 42 characters per line, two lines per cue, and a six-second maximum. No API key and no upload step — the model runs inside the Actor. Direct media files only; platform URLs such as YouTube are not supported.

## Input

```json
{
  "media_urls": [
    "https://www.nasa.gov/wp-content/uploads/2023/07/gafinale081222.mp3"
  ],
  "max_chars_per_line": 42,
  "max_lines_per_cue": 2,

  "language": "auto",
  "task": "transcribe",
  "vad_filter": true,

```

## About this Actor

This example demonstrates how to use [SRT Subtitles Generator — video & audio to SRT/VTT captions](https://apify.com/amanatools/srt-subtitles-generator.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/amanatools/srt-subtitles-generator.md) to learn more, explore other use cases, and run it yourself.


## 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.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **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).
