I would strongly suggest taking some time to first review ALL of the info that came with your Mavic; next downloading, reading and digesting the online Mavic manual if you haven't done so already; and then searching YouTube for any of the numerous videos that are out there that go into great detail about every aspect of the Mavic, including the best proven camera settings. There are countless videos out there, ranging from out-of-the-box videos to in-depth vids on flying the Mavic, filming, taking pictures with it, details on its many features, literally anything you could think of regarding this machine has already been covered by numerous videographers.
Bookmark the videos that teach you the most and watch them repeatedly until you either have what you need to know ingrained into your head or you are at least sick of them, which for me ends up being about the same point. Seeing is believing, and there is nothing like having first-hand, realtime instructions at your disposal that you can pause, rewind or FF through to focus on exactly what you are looking for. Even just typing "Mavic Pro" into the site's search engine will launch you into Mavic video La La Land.
Of course, the folks in this Forum are very good about answering your specific questions if things happen not to work out as they are supposed to according to the manuals or Mavic videos. But I'd start with YouTube first. Good luck.
