The red "focus peaking" is shown on your app's PREVIEW of footage (iOS only) so you can be confident the focus is accurate on the areas that matter to you. Adjust with manual focus if the camera is not focusing on the desired subjects. It is not saved to the cached instant-replay video on your phone/tablet, nor does it appear on the actual footage on the Mavic's microSD.
The white "highlight peaking" or "zebra stripes" is shown on your app's PREVIEW of footage (iOS only) so you can be aware of areas of the image at risk for over-exposure and poor color fidelity. Adjust exposure to minimize the stripe effect, but not entirely eliminate it. It is not saved to the cached instant-replay video on your phone/tablet, nor does it appear on the actual footage on the Mavic's microSD.
