Add Music

Add a soundtrack or voiceover to your video from the royalty-free library or your own audio files, and see it as a waveform.

A soundtrack sets the pace of a video before a single word lands. Krumzi ships a small library of royalty-free tracks and also takes your own audio, so you can score a video without leaving the editor.

Adding a track from the library

  1. Open the Audio panel from the side navigation.

  2. Click Browse Music Library.

  3. Preview tracks with the play button.

  4. Pick one and it's attached to your video.

Every library track is royalty-free and cleared for use in the content you make with Krumzi. No attribution needed.

Uploading your own audio

In the same panel, drop a file onto the upload area. MP3, WAV, M4A, and AAC are accepted, and you can also drop an MP4, MOV, or M4V if you want the audio from a video file. This is how you add a voiceover you've recorded elsewhere, or a licensed track you already own.

What you get on the timeline

Once audio is attached, its waveform is drawn across the timeline. Use it to line things up: split a background segment where the beat hits, or start a headline's entry animation on a drum hit. Drag the playhead to a peak, then press S to split, or drag an element's bar so its edge snaps there.

Replacing or removing audio

A video has one audio track. To swap it, remove the current one with the remove button in the Audio panel and add another. Video elements keep their own volume slider, so you can mute clip audio and let the music carry the video, or the other way around.

Music and video length

  • Match the energy. Upbeat for promos and announcements, calmer for tutorials and testimonials.

  • Try to end the video on a natural pause in the track. An abrupt cutoff is the first thing viewers notice.

  • Add the music early. It's much easier to time visuals to a track than to force a track onto finished visuals.

Ask the AI

The AI chat inside the editor can attach audio and align scenes and animations to it. If you already have a track on the timeline, ask for "cut to a new scene on every strong beat" and check the result against the waveform.

Tips

  • Keep the mood consistent across a series of videos. The same track, or tracks in the same style, becomes part of your brand.

  • Watch the final preview with sound on before exporting. Mute-while-editing is handy, but you want to hear the real mix once.

  • Exports include the audio track, so what you hear in the preview is what viewers hear.
