Words from the audio, then into the video.

This 19-second example uses original words read by an AI voice. We ran the audio through the same Extract lyrics tool below, applied its six recognized lines and start times, and exported this WebM in Barz.

AI spoken voice, not singing. This demonstrates the workflow. Fast rap, singing and loud backing tracks can need more correction.

  1. 0.24s I catch the last train under silver light,
  2. 3.36s a little rhythm keeps me moving through the night.
  3. 6.48s I write a new line while the city sleeps.
  4. 9.44s One small promise is the only thing I keep.
  5. 12.60s Turn a quiet thought into a sound, you know.
  6. 15.56s Take another breath and let the next word flow.

The recognizer changed punctuation. Always check the words and timing against the voice before exporting your own song.

FROM A FINISHED TRACK TO A FIRST TAKE

Keep your song. Build the visual around it.

Use a vocal demo, a recorded verse or a release you have permission to use. Barz keeps the original audio and draws timed text over a beat-reactive visual. You choose the look and review the words before exporting.

Make a lyric video from your audio in four steps.

  1. 01
    Load the track you want to use.

    Choose your file above and check its duration. A short vocal section is useful for a first take. The sample is an instrumental with prepared captions, so use your own vocal track to try automatic recognition.

  2. 02
    Extract the words, then review them.

    Agree to online processing and click Extract lyrics. The result stays separate from your draft until you apply it. Correct names, repeated hooks and words the recognizer missed; noisy mixes and fast rap need extra review.

  3. 03
    Play the captions against the voice.

    Use recognized timing, or play the track and mark each line. Adjust a start time if a caption appears early or late. Add a template, song title and optional cover, then preview the result.

  4. 04
    Export, then download your video.

    Keep this tab visible while Export WebM records the track. When it finishes, the main button becomes Download video (.webm). Save it before closing or refreshing the page.

For the full correction workflow and common timing problems, read the lyric timing and caption review guide.

Before you start your full song.

Do I need a lyric sheet?

No. Add a track with vocals, agree to the online audio processing notice, and click Extract lyrics. Review the result before using it. You can also paste your own lyrics and set their timing manually.

Can I start with an instrumental?

Yes, for a visualizer or manually written captions. An instrumental has no sung words to recognize. The built-in sample uses an instrumental with sample captions; it demonstrates editing and export, not vocal recognition.

What happens to my uploaded video?

MP4 and WebM input use the audio track to create a new lyric visual. The original video picture is not kept or captioned. Use your cover or a photo in the editor for the new background.

Can I download MP4 or a subtitle file?

The editor currently downloads WebM with your audio and captions in the picture. MP4, SRT and LRC export are not available. Check that your next editing or publishing app accepts WebM before starting a full export.

Is my song sent to a server?

Selecting, previewing and exporting a track are local. Only when you agree and click Extract lyrics is the audio temporarily sent to an online recognition service (Qwen or Volcengine Seed Speech). The temporary audio is removed after completion or cancellation, with automatic expiry within ten minutes. Successful recognitions keep a converted copy for up to about 30 days to improve recognition; cancelling before completion or a failed recognition deletes it immediately.

Can I use the same draft in the rap editor?

Yes. These pages open the same Barz editor and share the draft saved in this browser. Keep the original audio file: reselecting it after a refresh restores playback, while a different file requires new timing.

For longer tracks, higher resolution and additional aspect ratios, see the Free, Pro and Max plan details. Only use songs and lyrics you own or have permission to use.
