When I do a quick editing on the DJI app by just adding a different view and a song I can't get it to save as 4k. I save the video and upload it to YouTube but I can never view it above 720...even if I wait a day. If I just save the video and upload it to YouTube without editing it plays in 4k. My question is. Does the DJI app just restrict it from anything more than 720 or am I doing something wrong.
