Video Edit Magic has a Preview window that lets you see how your video composition looks while your are editing it on the Timeline. The preview window always displays the video at the position of the Timeline's slider. Drag the Timeline's slider to preview any portion of the Timeline.
If you want to preview only a particular source, you can right-click on it and select Play Clip or double-click on it. This is useful as you do not have to preview the entire Timeline.
You can also use the preview window as a media player for your Timeline. To control the preview click the Play, Pause and Stop, Rewind and Forward buttons. The Previous Frame and Next Frame buttons lets you preview your Timeline frame-by-frame for precise editing.
To preview the Timeline in full screen, open the View menu and click Full Screen Preview or use the Ctrl+Q shortcut key. To switch back to normal mode press Alt+Tab or Ctrl+Q again.
