Saving contiguous video files onto computer

Hi, I have a floodlight cam above my garage door. I occasionally work on projects in my driveway, and want to save some of the videos on my computer as a log. I want to save a string of contiguous 1 minute videos with a timestamp to a folder. I can do it one at a time if I select the video, and then save\_video\_as... ANd that works just fine. Howver, doing it for a 4 hour stretch means 4x60 files. Is there a way to save a group of files all at once? Thanks duglmac
