If you have shows whose broadcast duration is less than 30 minutes in length, you can choose how to represent those shows in the Calendar Preview.
Enable the Exact Time Rendering option to represent these shows according to their actual scheduled duration in the calendar. Your Calendar Preview will include blocks of time you may have difficult identifying. Hover over the show block for details.
Clear the Exact Time Rendering option to display all shows less than 30 minutes long as a minimum of 30 minutes. Your Calendar Preview will be less accurate than the actual show schedule. Hover over the show block for details.
