I am new to flying a drone, and am learning to use a new mini 2, and my 4k 30fps videos are splitting into two files after 5 mins-25 sec.  Am I doing something wrong?  Do I have a setting wrong?   I am using a 128 gb Sandisk Extreme Pro Micro SD card, and it is not getting anywhere near even partially filled.

I’ve found that out not to long ago as well but just know your doing nothing wrong it’s just how it is as when shooting a video that goes longer then four minutes will it cut it in half.

Hello there. Thank you for reaching out and for giving out these information. 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. Thank you.

It's perfectly normal. 4Gb is that maximum filesize possible on the Fat32 system used. So you've gone over into a second file, is all.  When you play the video back you won't see an interruption in the sequence, it just carries on into the second (and subsequent files if there are any) without pausing.

Thank you to all who have been so gracious to reply with the explanation for my dilemma.  I am new to the drone hobby, and I have been getting so much enjoyment that I wish I had discovered this amazing passtime a long time ago.
