sum_clip_durations

This function calculates the sum of clip durations for a specific row and search criteria

Basic format: ["sum_clip_durations", "row_name", [search_criteria] , "start_time", "end_time" ]

In the following example, we want to know how long the combined length of ball in play clips total up to during the game. The sum_clip_durations function works by calculating the length of each clip in the timeline which exist in the "Ball in Play" row. With no search criteria defined, the function will simply search all clips regardless of any qualifiers or attibutes that might be present

e.g: ["sum_clip_durations", "Ball in Play", [] ]

You can also define a start and end time which is also useful with the min_time_start and max_time_end functions - ensure you define the timing variables before you use them in this function.
