MORE TIME WITH THE MUSIC YOU CHOSE.

Make Music Longer for Your Video

Your video doesn’t have to run out of music halfway through. Reuse parts of your recording to fill more time, then listen to the repeats and ending before exporting.

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 the music to reuse

    Choose a short recording. We repeat existing audio rather than invent a continuation.

  2. 02

    Set how long it should last

    Choose up to three minutes, or add a video to use its duration.

  3. 03

    Make the repetitions feel right

    Listen at restarts and the final cut. Try another section or revise the ending before downloading.

ONE WAY TO USE IT · ILLUSTRATION

Fill the rest of the clip

Repeat sections from the 20-second source and adjust any distracting restart. Adding a video keeps its picture unchanged.

Try your version
0:20 music + 1:00 video1:00 repeated soundtrack

Extend the duration, not the composition

An instrumental passage may work well repeated, while a verse repeated twice may feel obvious. Choose a section that serves the video and preview it against the picture.

The output limit is three minutes. This does not create new verses or a soundtrack for a longer film. You can export a WAV to continue editing elsewhere.

A few things you might be wondering

Does it generate new music?

No. It repeats or rearranges existing audio. Preview those choices before downloading.

Can it finish with my video?

Add a target video to use its duration. The arrangement must fit; listen to the last repetition to decide whether the ending works.

What happens to my recording?
