The Paralenz is a good dive camera but annoyingly cuts the videos into small chunks at it saves them which you either need to use their crappy software to recombine or do it by hand. Or you can point this app at the directory that contains the videos and it will figure out which videos belong together and recombine them for you. It tries to be smart so you end up with videos for each of the individual dives, not just one big one with everything that was on the camera.
