# Make a Karaoke Lyric Video from a Song

**Use case:** 

Turn a song and its lyrics into a karaoke-style lyric video: every word is timed to the singing, the current line fills with colour and the next line is previewed, on your image with a slow zoom. Example: a public-domain U.S. Navy Band recording.

## About this Actor

This example demonstrates how to use [Auto Captions & Lyric Video Maker - TikTok Subtitles, Karaoke](https://apify.com/kantolabs/auto-captions-lyric-video.md) with a specific input configuration.

## 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/kantolabs/auto-captions-lyric-video.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`).
