Understand music and sound effects in clips

The AI picks a music track for every social clip from Clevera's library of 190 tracks and places sound effects from 279 more. Learn what you control before you generate, why the music fits the cut, and how to change both in the editor.

Every social clip comes with music and sound effects chosen by the AI. Before you generate, you decide only one thing: music or no music. Afterwards, in the clip editor, you can swap the track, change its volume, or add and remove sound effects.

What you control before you generate

The Music pill ("The bed under the voice.") has two options:

The Music menu with Pick a track for me selected and No music below it
Option What it does
Pick a track for me (default) "A track that fits the pace and mood." The AI picks one track for the clip.
No music "Voice and sound effects only."

There's no track picker on the Compose page, on purpose: the track is chosen together with the cut, so it can be fitted to the clip's scenes. You choose a specific track afterwards in the editor.

Sound effects have no setting before you generate. The AI director places them as it builds each scene.

How the AI picks the music

Before the AI director starts on the scenes, a separate AI step picks one track from Clevera's music library of 190 tracks in five moods:

Mood Feel
Calm & Focused Low-energy, focused underscore
Cinematic & Inspiring Sweeping, cinematic lift
Upbeat & Motivational High-energy, driving motivation
Warm & Human Warm, acoustic, human-feeling beds
Modern & Techy Modern electronic, tech-forward grooves

The pick follows the clip's type, tone, pace and length. Then the track is fitted to the cut:

  • It's cut into pieces that land on the clip's beats, so scene changes hit with the music instead of drifting.
  • On short clips and fast openings it can start at the track's groove rather than its quiet intro.
  • It dips under the voice wherever someone speaks, and comes back up between lines.

If no track fits, the clip finishes without music and the generation page says "Heads-up: I could not find music that fit, so this one runs without a bed." You can add a track in the editor.

How sound effects are chosen

The AI director places sound effects scene by scene from Clevera's library of 279 effects in 18 categories, among them Transitions, Impacts, Risers, UI, Notifications, Stingers, Emphasis, Achievement, Foley, Ambience and Timer. A whoosh on a transition, a click when a button is pressed, a riser before a reveal: each one is placed on the frame it belongs to.

Change the music in the editor

  1. Open the clip settings

    Open your finished clip and click Clip settings on the icon rail beside the video. The Settings page has a Sound section listing the music, the Narration (number of lines) and the Sound effects (number of effects).

  2. Select the music

    Click the music row; it shows the track's name and "Background music · 40%" (the volume). If the clip has no music, the row reads No music — "Nothing plays under the clip" — with an Add music button.

    The clip editor's Settings with the Sound section listing music, narration lines and sound effects.

  3. Pick another track

    Under Track, open Choose music. Search the library (Search tracks), filter by mood, and press play to preview before you pick. You can also upload your own track, or click Remove track.

  4. Fine-tune

    Set Volume, and under More options set Fade in, Fade out and Start at. A track the AI fitted to the beats shows Fit ("Cut into pieces that land on the video's beats. Picking another track cuts it the same way.") instead of Start at. When the track dips under the voice, Ducking ("The track dips under the voice along these points. Volume scales them all.") shows how many dip points it has.

    The background music panel with track, volume, loop, fade in, fade out and fit.

A track you upload yourself is your responsibility: make sure you have the rights to use it.

Change sound effects in the editor

  • Add one: open the editor's add menu, go to Sound and add a sound effect, then Choose a sound effect from the same library, or upload your own file.
  • Change or remove one: select it on the timeline and pick another effect, change its volume or delete it.
  • Ask the assistant: for example "Remove the sound effects in the first three scenes" or "Use calmer music". See Ask the assistant to change your video.

Changing music or sound effects by hand doesn't use credits.

Videos from your recording

How-to videos, product demos and Polish take their music from the video template you choose, and you change it in the editor's Audio tab. Articles have no music. See Change voice, music and sound.

Troubleshooting

What you see What to do
"Heads-up: I could not find music that fit, so this one runs without a bed." Add a track in the editor: Sound → Add music.
The music is too loud under the voice Lower Volume; the ducking points scale with it.
I want one specific track in every clip Pick it in the editor after each clip is made. There's no track choice before generating.
The clip is silent If the voice failed, the page says "Heads-up: the voice did not come out at all, so this one is silent." See My video came out silent, without music or without the avatar.
