The Multiple Trim window is used to additionally split the clip at the Storyboard into scenes, or quite the other way round, merge the scenes in the clip.

To open the Multiple Trim window click the button in the Storyboard view of the Workspace or click the clip you would like to edit with the right mouse button and select Multi Trim... You will see the following window:

The following buttons are used to trim the selected video:

Button	Caption	Description
	Play/Pause	Use this button to playback or pause the selected video to find the scenes you need.
	Stop	Use this button to stop the selected video playback.
	Previous/Next Frame	Use this button to go to the next or return to the previous frame of the selected video.
	Mute	Use this button to mute the sound of the selected video.
	Fade in	Use this button to set the initial scene point of the selected video.
	Fade out	Use this button to set the final scene point of the selected video.
	Add/Split Scene	Use this button to add a scene at current position or split the already selected scene into two parts.
	Start/Stop Scene Detection	Use this button to start the automatic scenes detection. When in progress, this button is used to stop the scenes detection process. Note: you can select two scene detection modes - Detect scenes changes or Detect TV commercials from the drop-down box next to the button, depending on the type of the video you edit.

All the scenes that have been found during the scene detection process or that you selected manually will be displayed in the scenes list. You can highlight any of them with the mouse and delete them with the Delete button, if you decide to remove them from the video.

It is also possible to merge two or several scenes into one. To do that simply select several scenes with the mouse (you can use the Shift or Control buttons on the computer keyboard to simplify the selection process) and click the Merge Scenes button to join the selected scenes together.

After you select all the scenes click the OK button. All the scenes will be added to the Storyboard and will be represented as separate clips there.
