i think this is not entirely correct. according to the manual, |
| 18 |
"When used in conjunction with −ss option, −endpos time will shift |
| 19 |
forward by seconds specified with −ss." |
| 20 |
|
| 21 |
that means that if you want 90 seconds of film, you must use -endpos 90 |
| 22 |
or -endpos 1:30, independently from the time given in -ss. see the |
| 23 |
example from the man page: |
| 24 |
|
| 25 |
EXAMPLE: |
| 26 |
−endpos 56 |
| 27 |
Stop at 56 seconds. |
| 28 |
−endpos 01:10:00 |
| 29 |
Stop at 1 hour 10 minutes. |
| 30 |
−ss 10 −endpos 56 |
| 31 |
Stop at 1 minute 6 seconds. |
