Not commercial quota relevant
In some countries, the percentage of an hour in that you are allowed to broadcast commercials, is limited. But not all elements which are broadcasted during a commercial break add to that percentage, like commercials for an election. Elements, which do not add to that percentage, can be marked not commercial quota relevant.
Length: The length of a commercial version (in frames) is taken over from the commercial, yet can be edited manually. It is used to calculate the commercial capacity utilization (in the Planner). Here, the non-commercial length is subtracted from the length (given that the ad check is activated for the respective client).
Non-commercial length: This length in frames informs about the part of the commercial version which is NOT commercially relevant. It can be set manually and will be subtracted from the general length of the version for calculating the commercial capacity utilization.
