When a video slice is selected, its beginning time and end time are displayed below the time line.
Please note the "Link to previous slice's end time" setting and "Link to next slice's start time" setting.
Link to previous slice's end time - When set, the selected slice's start time is always connected to the previous slice's end time. If one time setting is changed, the other one is changed automatically.
Link to next slice's end time - When set, the selected slice's end time is always connected to the next slice's start time. If one time setting is changed, the other one is changed automatically.
The time line draws the slices differently according to those settings.
