FAT32 isn't useful for mass storage of video files because of its 4GB file size limit. And exFAT/FAT64 is not only patent encumbered, but it also uses only one FAT so it's actually less resilient in the face of any kind of corruption, and isn't intended for this use case.

They should probably use NTFS instead.
