Hello there!! I know you are a newbie and getting used to the controls and flying smooth will require a few hours of flight time but one area where you can instantly improve is the exposure settings. Your video is a very good example to demonstrate how exposure continuously changes when you are in AUTO mode and it doesn't look good in your captured footage. Won't advise to fiddle too much with manual exposure settings though. Just set one of the customisable buttons on your RC to AE lock/unlock. After that, simply point your camera towards a moderately exposed region in the area you are filming and once the camera has automatically selected the exposure, hit the AE lock button. When you shoot with AE locked, the exposure will not continuously change as you move or pan from shadow areas to lit areas or vice versa, which is happening in your video now.
