I have bought and tested Litchi, AutoFlight and AirNest. All three of them DO NOT HAVE these two functions...."Peaking" and "Zebras" These are crucial tools, along with the histogram for making successful, properly exposed and focused video. Every professional camcorder has them. The DJI GO app has them. With borderline picture taking capability it is crucial not to cause clipping of the video waveform. You only have a small dynamic range to work with. I am really surprised these functions haven't been included. It means you must switch back to the GO APP to get them....not a great idea in the middle of a mission!
