Audio Components

Your video can include up to two audio layers:

  • Voice-over — AI-generated narration from your script

  • Background music (BGM) — Music track from the library

Adjusting Volume Levels

Control the volume of each audio layer to get the right balance:

  • Voice-over volume — Keep this prominent so narration is clear

  • BGM volume — Lower this when voice-over is present

Audio Mixing During Export

When you export your video, audio mixing happens automatically:

  • Voice-over and BGM are combined into a single audio track

  • Volume levels you've set are applied to the final render

  • The result is a single MP4 file with all audio included

Muting Audio

If you want to export without audio or with only one layer:

  • Disable voice-over if you want music only

  • Disable BGM if you want voice-over only

  • Disable both for a silent video

Audio Sync

The voice-over is synced with your animation timeline. If you adjust the animation duration, check that the voice-over timing still makes sense. You may need to regenerate the voice-over for a different duration.

Tips

  • Test on different devices — Audio levels can sound different on speakers vs. headphones

  • Keep BGM at 20–30% volume when voice-over is present for a professional mix

  • Preview the full video with audio before exporting to catch any timing issues
