Every 2 Filter has an Input type. 

The Input Type is solely used to tell the Media Manager and Video Portal how to gather input from a user. If a 2 Filter is not a Visible filter, then the Input type is irrelevant.

The available Input Types depend on the selected 3 Comparison Type. See Comparison Type - input Type and Comparison Type - Value Type combinations for the relationship between Comparison Types and Input Types.

The Input Type of a filter is defined during creation of a filter:

Creation of a filter.

It can be edited in the The Details panel.
