Why are my 4K recordings maxing out at 3.67GB?

[Ran4]

Whenever I record a 4K video that's longer than around 5 minutes, the software is automatically splitting into multiple files. ...and each will max out at 3.670GB. I've already stayed in the air recording for 15 minutes or more, and each time I'll have 3 or more separate files on the SD card.

You cannot change that, its done by default .

Thanks. Yes, a Google search has yielded me the same answer. So, I suppose the only way to get a longer 'uncut' video is to downgrade the camera setting to 2.7K or 1080p, and/or a slower frame rate, right? When I fly tomorrow, I'll experiment with 2.7K and 1080p..

Just join the vids end to end in post.

I think you're bumping into the max file size on the SD card.

Like @Thomas B indicated, just join the clips end to end. They don't miss a beat. All joins in post have been perfect to my eye.

No, it’s DJI programming of the recorder. Not a card issue.

If the card is 32GB or less, then it would be formatted FAT32, which has a file size limitation of 4GB. EXFat, used when card size is greater than 32GB, can handle bigger file sizes, but DJI probably wants to stick with the lowest common denominator. Probably too they did that so if one was copying the file to another storage formatted FAT32, the copy won't fail and confuse the user.

Thanks folks. I've been reading elsewhere that this is normal. BTW, I'm using a 64gb card. I'm going out this morning to experiment with some longer videos in both 2.7K and 1080p.

The limitation is the AVI container, it uses 32bit addressing- 2^32=4GB.

DJI has put on the limit and nothing you can do to change it.

Also, it's a little insurance against an error corrupting the entire video file. Given the storage media, power situation, it makes sense from that perspective too.

No. It’s a max file size of FAT32.

No - no one would format FAT32 on purpose - eXFat format is preferred.

If the card was formatted in the drone/app, it would have been formatted to FAT32.

 

[TreeHugger]

Ya got me - I need to pay more attention to which forum I post in.
My drones format a freshly wiped SD card as Exfat by default.

It does not matter if your right. This subject has been discussed in other post and the answer is still...... DJI sets the limit.
If you do not believe me then check the other post here and on DJI forum.
It does not matter if it is FAT32 or Exfat.

The fact Fat32 has a 4GB limit is not the issue here. Feel free to try yourself on an exFAT volume. The limitation is the AVI file container structure, 32bit internal memory addressing. Obviously it is not a DJI specific issue either.

...and for the record, it's not just a DJI thing. I know for sure that Autel drones do the same thing

Having the ability to record 4K/60 fps and back to 2.7/60...do not do it. The video longer than 5 minutes will be splited again, so you will not have something better here, but you will lose the amazing 4K/60 video...just use some software and join the parts...
