I record a 10 min flight video and end up with 3 mp4 videos . I am using the recommended 512 sd card . I have never had this problem before using mov. Why does it stop and start again after recording for just over 3 min?

I believe it has to do with file size - this post may explain what you are seeing:

How big are each of those 3 files?
4k 30 video splits into 2 files after 5 min 25 seconds
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...
How big are each of those 3 files?
Is there a maximum permissible file size, what size are the segments of each video? lol beaten to it by a second or so.
According to the post I shared above, the file systems in question are limited to 4GB per file.
There is a filesize limit of approx 3.7GB.
This applies whether you record in MP4 or MOV formats.
There is no way around it.
You can have longer file segments by shooting at a lower resolution or frame rate.
I will run trials with different settings.I have 12 min mov videos on my Mavic Pro Platinum.

Of course since the quality and thus filesize is way slower.
Anyway you can seamlessly merge them afterwards, so not a big deal.

The higher the resolution, the larger the files will be. If you are shooting at 4k/60fps the file will be significantly larger than a 1080p video.
You can easily determine if this is the cause by looking at the 3 files you have on your card already. If they are near 4GB, you have your answer.
You are correct .The files are all just around the 3,600,000 KB range . How do I lower the resolution?
Depends on what app/controller you are using. It should be in the user manual. For the DJI Fly app on a mini 3 pro:
Page 54, at the bottom of the screen #15 will get you to the option to change the resolution. Yours may be different.
The first think to look at would be the frame rate you are using.
If it's 60 frames/sec, that makes a big difference ,, drop that to something between 25 and 30 fps.
Hi Meta4! I would reconsider lowering the resolution. You will be sacrificing picture quality for the sake of having smaller file sizes. As Kilrah mentioned above, the files are seamlessly merged. It's common for me to record a 20 minute flight and come home with 5 video files (or more). I'm assuming you are using some kind of video editing software on your computer to make final movies, if so, just 'drag & drop' them on the timeline and you will have flawless transitions from one file to the next. On my big screen TV I can TOTALLY notice the drop from 4K to 1080p. Personally, I can't stand it. This is all just my opinion. Mike
You are assuming that I do a lot of video, but I hardly shoot any.
I was simply answering the OP's question and you should note that the first thing I suggested for him was to check his frame rate.

I'm not aware of framerate changing the bitrate on DJI aircraft, but maybe the M3E is different.
A little testing with a Mavic 3 shows that reducing the framerate does reduce the filesize.
But only 10% ... not as much as I had assumed.
I haven't had the need for editing in the past with small file sizes. What software are you using ?
So reducing resolution would be the way to have segments go for longer.
What resolution is the camera set on?
Here's how you check and change it:
The video settings are shown in the bottom right.
This is showing 5.1K 30 fps
To change reduce the resolution, tap the settings and slide the top line away from 5.1K to 4K and see how that goes.
You can do a test shot on your desy without any need to start the motors.

I don't shoot video.
But if you previously didn't have many 3.7GB file segments, you must have been shooting a lower resolution that 4K.
