There are two ways to remove a video clip from a template target ares in GoPro Studio.

  1. Simply replace the existing clip that is in that target area with the desired clip.
  2. You can Undo the adding of the clip by pressing CRTL+Z (PC) or Command+Z (Mac), or by selecting Edit > Undo. The Undo option is best only if the clip you want to remove was added as your last action. If it was not your last action, the Undo will remove some other change.

It is not possible to remove a clip from a template by using the Delete key or by dragging the clip to the top of the Storyboard like in a Blank Template.
