# Convert a video to SRT and VTT subtitles automatically

**Use case:** 

Transcribe a two-minute NASA video (WebM) and get ready-to-upload SRT and VTT subtitle files with accurate timestamps, plus the full transcript. A vocabulary hint (NASA, Artemis) keeps names spelled right. Paste links to your own MP4, MOV or WebM files, or public Google Drive and Dropbox links, to caption videos for YouTube, courses or social media.

## About this Actor

This example demonstrates how to use [Audio & Video to Text - Speech to Text Transcription, SRT](https://apify.com/tidytools/audio-transcriber.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/tidytools/audio-transcriber.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

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

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/tidytools/audio-transcriber.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
