I upgraded from PowerDirector 16 to 365 (subscription). The Timeline Ruler goes displays in seconds, I think, but for some reason goes from 1 to 1:29 then becomes 2:00 and goes to 2:29 and becomes 3:00. Why is this? The PD16 version goes to 1:59 then becomes 2:00. I don't see a way to change this under preferences.
