I really dislike the 4Gb boundary from the old MS DOS days and really don't understand why DJI doesn't allow EXT format or NTFS format SD cards to overcome the split in large files (over 4Gb).  Yes, I know I can use an app to put the pieces together, but why should I have to?

So I guess I'm asking DJI directly why this obviously sophisticated, obviously expensive drone to write video to an NTFS or EXT formatted card???

In other threads DJI forum admins have stated that it's in your best interest to partition video in 4GB chunks, that way if a problem happens and the video file is unable to close, your entire flight's video won't have been lost. It is a common question and request, though, that purportedly has been forwarded on to DJI engineers for consideration.

On my GoPro camera a long video clip is chopped into 1GB files. I never found this to be of a problem.

At least there's no stutter or chop in the video if you splice them together or play back-to-back in VLC (for example).  A lot of the tech is old school mixed in with space-aged.  It's weird.

Interesting. Wonder if for the same failsafe reason?

I don't know the reason, it's possible that this is documented somewhere, but I couldn't find it.
BTW, the dashcam (not a GoPro) in my car also records the video clips in 1GB slices.

Everything you've said is accurate.

Problem is Fat32 File System has a max file size of 4GB. So this is usually the set limit for compatibility reasons even if a file system allows larger file sizes, should you want to copy the file to a Fat32 disk. Btw: you can close an "unclosed" video with tools.

Sounds reasonable but I'd sure like an option in the software to do it if I want to.
