 On actual drawtext filter there is a small bug.
 If you set the timecode='23\:59\:00\:00' or any hour less than 24 hour,
 you will notice that the timecode does not reset after 23:59:59:24 to
 00:00:00:00 but will continue over 24:00:00:00

 That is not common; most of the broadcast video equipment I've seen so
 far, keeps the hour counter onto: 00-23 domain.

 Another drawtext related issue is how can one set timecode as system clock
 with frame count HH:MM:SS:FF (FF frames count)? or more explicitely how to
 set exact frame on the time of the day system clock which is meant to be
 burned-in video ?
