Comment (by LordHDL):

 59.94 is just an example, that's not always what it rounds to.  The
 software I use to record captures frames on arrival as opposed to me
 specifying a fixed rate, hence the video may wind up with a rate like
 59.91 or something odd.  I could wind up with 59.94 and ffmpeg will round
 that up to 60, or I may get something non-standard.

 Is `-r` as an output option the correct way to prevent this?
