I'm new to using a Mavic 2 but have been using Camtasia for video editing for years. What puzzles me is the Smart Controller installed 32MB of music files on my SD card (e.g. "Cool_City.m4a" found under: E:\DJI\dji.go.v4\editor\music\music_file), which suggests I can potentially play music while showing my videos from the SD card or mix the music with a video while I'm creating it live. But I can't find anything on the internet to explain how to do this. Any thoughts are appreciated.
