CapCut: Adding sound effects and background music

Demo summary
The creator demonstrates syncing whoosh and glitch sound effects to visual animations and adjusting background music volume to -20dB.
Step-by-step
- Import sound effects into a folder and drag the desired clip onto the audio layer below the video.
- Align the sound effect waveform with the visual transition on the timeline.
- Adjust volume by dragging the horizontal line on the waveform or using the Basic tab in the audio settings.
- Shorten long sound effects by dragging the edges of the clip to match the duration of the visual animation.
- Create a natural introduction for harsh sounds by dragging the small dot on the clip to create a fade-in.
- Import background music and drag it onto a new audio layer.
- Lower the background music volume to approximately -20dB to ensure it doesn't overpower the dialogue.
Options
- Adjust volume via the timeline waveform line or the Basic settings tab
- Use free music from YouTube's audio library
- Use paid music from Epidemic Sound
Tips
- Add sound effects at every opportunity possible throughout the video to enhance the edit.
- Use your ear to finalize volume levels as the ideal DB depends on whether the song is naturally loud or quiet.
- Break the video into chapters by introducing a new song for each new segment of the video.
