# AI lyric video generator: song to synced lyric video

> **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>"` returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the how-to page. From a terminal: `curl -fsSL https://varg.ai/install | sh` installs the vargai CLI (https://varg.ai/how-to/cli.md): `vargai search` and `vargai install <slug>` with no key, every varg model after `vargai login`.

Give your AI agent a song (MP3 or WAV) and its lyrics and get back a lyric video with every line on the vocal: 9:16 for TikTok and Reels or 16:9 for YouTube, as an MP4. The lyrics are drawn in code on top of the picture, so every word is spelled right and appears when it is sung; no video model is asked to write text.

**Price:** 5 credits ($0.05) a song on varg, for the word timings ([`whisper_large_v3`](https://varg.ai/models/whisper_large_v3.md)); the render runs on your machine and is free. **Free start:** new varg accounts get 50 free credits, enough for 10 songs, and with Whisper on your own machine the whole video costs nothing. 1 credit = $0.01. Checked against the public price list on 2026-11-11.

Paste this into Claude Code, Codex or Grok:

```text
Make a lyric video for ./song.mp3 with the lyrics in ./lyrics.txt: 9:16, karaoke style,
the sung line big and each word lit as it is sung.
Follow https://varg.ai/how-to/make-a-lyric-video.md.
Show me a timing proof and six frames before the full render.
```

The agent needs two skills, installed once (HyperFrames renders the video, varg gets the word timings):

```bash
curl -fsSL https://varg.ai/install | sh && vargai install hyperframes varg-ai
```

## What goes in, what comes out

| In | Out |
|---|---|
| The song: an MP3 or WAV you own or have licensed | One MP4 the length of the song, 1080×1920 (9:16) or 1920×1080 (16:9) |
| The lyrics as text | Each line on screen when it is sung, the current word lit, karaoke style |
| Optional: cover art or footage for the background, and a look | The project folder, so a wrong line is a text edit and a new render |

## How it works

1. **Word timings from the vocal.** One varg call (the `transcription` tool, `whisper_large_v3`, your lyrics as the prompt) returns a start and an end for every word: 5 credits. Without a key, `npx hyperframes transcribe song.mp3` does it on your machine (add `--model small --language es` for a song that is not in English).
2. **Lyrics drawn in code.** HyperFrames renders HTML to video, so the type is real text: `npx hyperframes init lyric-video --resolution=portrait --audio song.mp3 --skip-transcribe --non-interactive --skip-skills` (`--resolution=landscape` for 16:9), then the karaoke block, `npx hyperframes add caption-pill-karaoke`.
3. **A look before the render.** `npx hyperframes check && npx hyperframes snapshot --frames 6`: the agent reads the frames and fixes a word that shows before it is sung or a line that runs off the screen.
4. **Render.** `npx hyperframes render --output lyrics.mp4`, on your machine, as many times as it takes.

## Looks

- **Line karaoke:** two lines on screen, the current word lights up as it is sung.
- **Word punch:** one huge word per beat.
- **Ballad drift:** serif words fade and drift up, for slow songs.
- **Build and slam:** the phrase builds word by word, then the hook fills the screen.

These are presets of the `motion-formats` skill (`npx skills add vargHQ/skills --skill motion-formats`). They render locally and cost nothing.

## What it is not

- Not a browser app. It runs in a coding agent with a terminal, with Node.js 22+ and FFmpeg on your machine.
- It works from your lyric sheet. Without one it can transcribe the song, but sung words come back with mistakes, so read the text before the render.
- AI footage behind the words is another job at another price: [How to make an AI music video](https://varg.ai/how-to/make-an-ai-music-video.md). The lyrics are drawn in code there too.

## Music and lyric videos for your song with AI agents

For artists, producers and labels: an AI music video directed shot by shot to your song, a lyric video, a beat-cut edit or a photo slideshow, with lip-sync on every sung line, made by Claude Code, Codex or Grok.
