Select the sound clip and adjust its position and length on the timeline. Use music for the intended scenes and sound effects at specific moments. Trim unwanted tails rather than leaving a long audio clip beyond the intended ending.

   Check Adjust the sound interval

Select the sound clip and adjust Volume (%) in Properties. The example uses 20%, but the right level depends on the recording and speaker. Play both together and check whether the words remain clear on a quiet device.

Sound-clip volume

This controls the music or effect in this clip. Adjust the speech clip separately to change the voice level.

Different from toolbar volume

Playback volume changes how loudly you listen while editing. To lower the music in the final video, change the sound-clip setting.

Fade-in is the time for the audio to rise; fade-out is the time to lower it at the end. The example uses 1.5 and 2 seconds. Use shorter fades for brief sound effects so their important attack remains audible. These are audio fades, separate from visual opacity.

   Enter Set audio fades

Enable Loop to repeat the source within the clip’s duration. Source start position selects where in the original audio to begin, not when the clip starts on the timeline. Use it to skip an intro, and listen across loop boundaries.

   Enter Loop and source offset

Review the opening, speech-heavy parts and ending. Whole-video fades in File → Export settings affect audio too. When combining them with music fades, check that speech does not disappear too soon. Finally, play the exported MP4 and review speech, music and ending.
