i think this is not entirely correct. according to the manual,
"When used in conjunction with −ss option, −endpos time will shift
forward by seconds specified with −ss."
that means that if you want 90 seconds of film, you must use -endpos 90
or -endpos 1:30, independently from the time given in -ss. see the
example from the man page:
EXAMPLE:
−endpos 56
Stop at 56 seconds.
−endpos 01:10:00
Stop at 1 hour 10 minutes.
−ss 10 −endpos 56
Stop at 1 minute 6 seconds.
