iPad Pro Video filenames ending with MOV vs mov

Hi, all the videos on my iPad were taken from the same device. I have never imported any video files to my iPad. How come some of the files ended with .MOV while others ended with .mov? What is the difference between the two file types?

They are exactly the same file types, just as sometimes it's JPEG, other time jpeg. Why they sometimes come out one or the other with the same s/w is beyond me - a slightly different route through the algorithms.
