Adjusting the volume is handled identically for both video and audio clips in GoPro Studio. Here is how to increase or decrease the overall volume of a clip.
- Select the desired clip in the Storyboard.
- In the Settings section on the right you will see the Audio settings. Move the LEVEL dB slider to the left or to the right to decrease or increase the volume.
If you want to add a Fade In or Out, this is done in the same Audio Settings section. Adjust the Fade In and Fade Out settings to the amount of time that you want for each fade. The image below shows a 2 second fade for both Fade In and Out.
