How to fix one side is .MOV and the other is .MP4

Well got a new camera but same model but has different featurs. Looks like one camera recorded in .MOV and the other .MP4. So now I’m stuck and one is 59.94fps and the other says 60fps. Now they won’t stitch any suggestions?

Your best bet is to update the firmware on the older one. As for the videos you’ve already taken, I don’t know if there is an easy way to change the fps.
