START WITH THE RESULT

What would you like to make?

Recommended first step

Tell us what you want to make, in your own words. You don’t need to know how to edit it—we’ll help you choose the next step.

Not sure yet? Choose a starting idea below, or try the practice beat.

Or choose what you want to create

Start with your video below, then add the music you want. The video sets the finished length. Replacement removes all original sound, including voices.

Editing starts on this device. Save to My Library uploads a private copy of your project files so you can return to them. Asking Grok sends your instructions, audio measurements, and any timed text—not the audio file. Speech timing, lyric timing, and stem separation upload audio only after you approve their displayed price.

FROM IDEA TO DOWNLOAD

Here’s how to make it yours

  1. 01

    Add your video

    Choose a video up to three minutes. Its duration becomes the soundtrack target.

  2. 02

    Choose the music

    Add a separate recording or work with the existing soundtrack. Tell us about a moment you want to line up.

  3. 03

    Watch, listen and export

    Create the audio preview, then build the video. Check the MP4 before downloading; export needs supported codecs.

ONE WAY TO USE IT · ILLUSTRATION

Music for a 45-second reveal

Mark a music moment and the time it should arrive. The editor checks that timing; it does not find visual cuts or rearrange footage automatically.

Try your version
Long song + 0:45 video0:45 soundtrack + same picture

Fit your existing music without recutting the picture

Shorten a long recording or repeat sections of a short one. The video’s duration stays fixed, so the proposed soundtrack must fit before rendering.

Replacement removes the original soundtrack, including speech. Keeping original sound mixes all of it at a fixed balance; it does not isolate voices or lower music automatically under talking.

A few things you might be wondering

Will it change my video cuts?

No. The picture is retained. This is soundtrack editing, not automatic video editing or captioning.

Can I line up a musical moment?

Yes. Enter a source-audio moment and when it should land. You choose the moment; automatic drop or visual-cut detection is not included.

What if MP4 export is unavailable?

Download the WAV and add it in your video editor. MP4 export depends on input and browser codec support.

What happens to my recording?

Editing begins on this device. Asking for suggestions sends your instructions, measurements and any timed text to the planner—not your audio. Optional paid preparation sends audio only after approval. Saving to My Library uploads a private project copy. Use recordings you have permission to edit. Read our privacy policy.
