I transferred two movie files from my iPhone 6S to computer.  Now I cannot open them.  I have tried various converting programs with no luck.  I tried changing to mp4 an mov extensions but again no luck.  Is there a way I can put them back on my iPhone,  I don't remember what the file extension was when I moved them.  ( I believe it was .mov but I could be wrong )
Camera settings are 4K at 30 fps
Appreciate any help with this video problem
