Quote removedHere is info regarding SD Card:
"For the DJI Mini 4 Pro, get a UHS-I Speed Grade 3 (U3) or V30 microSD card with A2 app performance rating for smooth 4K recording, with popular reliable choices being SanDisk Extreme PRO and Samsung EVO Plus/PRO, in capacities like 128GB or 256GB to balance space and cost, as recommended by DJI for high-quality aerial footage"
I hope it would help you.
