DJI do this on all their aircraft. It is a hangover from an old import duty law that taxed cameras differently to video recorders. The file will be split into segments with a maximum size of 4GB each. They can be joined seamlessly together using a video editor. It has nothing to do with the FAT file system.
Umm, that's not what I remember. The EU import duty thing was a max record limit of 30 minutes, so that a DSLR isn't classed as a "Video Camera". Not an issue now as you say, but the 4GB file limit is a left over from the FAT32 format, which isn't necessary now, due to the exFAT system supporting larger files than we have any storage devices to hold.
There is a case for chunking into files around this size, so that in the case of corruption you might be able to sacrifice a single file but save the rest, but generally there are data reclaim programs that can save corrupted files from the bin.
So yeah, in general is is a bit of a historical limit, albeit still a very common one. |
