You can replay previously recorded Audio/Video in Explorer Editor.
From the Screens panel, scroll to the screen with recorded media you want to replay.
Click the Replay icon of the Audio/Video to play it with your default media player.
The audio file can be replayed with Windows Media Player, which is available on most Windows platforms. For Video, you will need a media player that supports .webm format. We recommend using VLC Player for this purpose. You can get it free here
