I had just tested the Mavic Airs Smart capture mode without controller (Double Tapp the Fn Button on the backside) and then went flying for a few video shots.

To my dismay I had to realise that smart Capture seems to have set the Video resolution to 1080p/30 and I only noticed near the end of my batteries... sooo how do I prevent that? How do i set the air to ALWAYS film in 4k/30?

I noticed this last night as well. Used the astroid feature for the first time and was more bumed about the Auto Exposure than the 1080p video. Would have got the perfect shot if the mavic didn't over expose everything

Hey Seishiroa, sorry for the late response. The video resolution of Smartcapture is the default and cannot be changed, please kindly note and understand.
