Everytime I use my Phantom 4 Pro, there's always one or two corrupt video files when I transfer my files. What could be causing this issue?

Hello there capogear. I am sorry for the trouble this has caused and thank you for reaching out. Kindly please try using a different microSD card on your DJI Phantom 4 Pro to see if the issue will persist. For reference I will post the list of supported microSD card for the DJI Phantom 4 Pro. Thank you.
