There are two trim modes: Overwrite and Insert . Overwrite mode replaces the currently selected scene in the Storyboard. On the other hand, insert adds a new scene before or after the currently selected scene in the Storyboard. If there are already clips in the project, then Trim goes into overwrite mode by default, and the current scene loads into the trim page. In overwrite mode, exiting the trim page or choosing a new scene automatically applies any changes made to the scene's in or out points.

Kino does not automatically apply any changes in insert mode. One must click Before or After to apply a change in insert mode. It is entirely possible to switch to trim, thereby loading the current scene into the trim page, choose Insert from the Mode option menu, and then insert the "current" scene as a new scene. Likewise, it is entirely possible to load a new clip into the trim page while in overwrite mode and replace the current scene in the Storyboard.
