While playing back you have the ability to select which camera to view. You can press shortcut "c" to toggle through the three camera views (LOS, FPV and recorded FPV view), or press shortcut "1", "2" ,"3".
It is not possible to save the recorded flight data to disk. You can however upload the flight to Youtube, but in that case you need to record the video with a screen capture program (such as Open Broadcaster Software for example) first.
