On mini 3 pro. Max video file size i can get out are 3,670,000 KB is it normal ?. When the file gets bigger, it splits the video into 2 files. I have used Sandisk 64 GB Extreme and 128 GB Extreme Pro as cardsRegards Bent

The maximum capacity of a single file will not exceed 4GB. If exceeded,  the recording will be stopped, and a new recording will be started. In  addition, the maximum file size of FAT32 is 4GB. Hence, a file that is  larger than or equal to 4GB will be divided, otherwise, the file may be  lost or abnormal and cannot be read. Although exFAT allows a larger file  size, the larger file may be damaged due to abnormal power-off and SD  card removal, or even cannot be recovered. So the storage of the camera  is 4GB regardless of the file systems. So it is normal the video will be  split if it reaches 4GB.
