iMovie
I'm a novis iMovie user.
When I run a downloaded video in view window on the right hand top half, I can hardly hear my voice commenting on what's happening in the scene. Hence I can't edit the video ( such as trim, cut and etc.).
My mac' sound' in the menu bar shows it's max volume so is the view window's 'sound' says 100%.
What do I do to increase the volume while I'm editing a video?
my macOS is 10.15.7 Macbook pro
