What is "Compare" widget used for?

In the eMAM Director interface, “Compare” widget has been introduced to play and compare two different videos side-by-side. It is divided into a left panel and a right panel. Just drag and drop videos into the two panels to compare them. At a time, audio of only single video can be played. Toggle between the volume buttons of both the videos to play the audio of any one file. Both the video files will have single playback button (play/pause, forward, backward, go to start and go to end) to play and stop the videos simultaneously.
