So my timeline is in the seconds view and is using non-integer intervals... I realized when switching to frames that it's put the markers in natural spots for frame view... at 0, 500, 1000, 1500, etc. but then keeps those intervals in seconds view, so that I get 0, 16:20, 33:10... which are far less intuitive.
I seem to remember that when switching between views the intervals for markers would change to something more natural to that view, i.e. seconds view had more regular intervals of time, like 0, 15:00: 30:00, 45:00 etc.. How can I get the stops back at standard intervals of time? Is this a bug?
Try changing the zoom value for the timeline. I cannot reproduce your screenshot.
