Try to enter an array of pictures with the same eventlength of 0,5 seconds = 1/4 note.
1) What value do I enter under options/preferences/edit in seconds so pictures change on the beat? Entering 0,5 seconds does not work. Out of the grid with the first picture. (timelineabove is displayed in seconds)
2) Is there a way to sincronize pictures already entered in the track as a group, not individually? Also dragging the length of events does not seem to work. (ctrl+leftmousebutton +dragging) Ends automatically either go above or below. Won´t lock on the grid.
