Changing volume in a part of a clip

It would be realy nice if we could change volume just in a part of a video clip.

Scenario:

  • Video with a action and some spech in the middle
  • Music track added to the clip in a separate track
  • Want to lower the volume if someboady talkes with a nice fade in and out (not to 0% but 20%)

Could not find this option, other programs give you the option to add markers and “draw” a volume line, that would be perfect.

There are many ways the change the volume in a part of a clip.

One way is using Keyframes.

Another way is Filter Trimming.
