My DJI  RC controller shows the Mavic3 Classic is recording but there is no video after flight on the controller or drone sd card.

Hi there. Thank you for reaching out and we do apologize for the trouble. Can you please confirm what storage format you set on the DJI Fly app? Please select the SD card if you have inserted an SD card then check again to see if the issue persists. You may check this option by going to DJI Fly camera view > General Settings (3dots) > Camera > Storage. You may click the link below for more information on how to export the aircraft photos or video files. Please keep us posted. Thank you.

Hello there. May I know your storage location and what SD card you are using? Please make sure you are using one of the recommended SD cards on the list as they are proven to work properly:

Have a nice day.
