About Modifying Effect Production Element Parameters

Effects can be created in GV Director Composer to allow parameters to be set from the GV Director Touchpad menu. This provides the ability to make text changes, for example in a lower third or to change player names for a sports production, etc., in pre-production or even during a show. In addition, graphics can be offset and live inputs can be selected when needed, for example in a two-box effect.

Effect parameters are set in the GV Director Touchpad Effects menu. When an effect has been setup by the author to require parameter setting changes from the Control Surface, a question mark will be displayed in the upper right-hand corner of the effect’s menu button icon. Access the effect parameters through the radial menu (double-tap, hold, and drag until the Parameters ring is highlighted and release). The author in composer will have defined the parameters and if text is required they will have indicated the field name; for example Lap Time.

There are two ways to enter in data:

Enter text directly using the keyboard; accessed by touching the Keyboard button. Once the data is entered and saved, the question mark on the effect button icon becomes a check mark indicating the parameter has been set.
Create a group of keywords using the Hierarchy button rather than the keyboard button; this group of keywords will be available for all effects. Groups are similar to folders. This feature is particularly useful if for example you want to set all the player names for a sporting event. Names or text entries can be organized into groups. Within the group, you can add as many values as you want. Those values are used while the groups are just organizational tools for data. A group name can be entered and the names or text entries will be grouped under that name in the hierarchy.

Another type of parameter is a background production element, for example in a two box effect. The author of the effect can require that the feed for each box is to be user defined from the Control Surface, resulting in a question mark in the upper right-hand corner of the effect's menu button icon. Instead of requiring a text entry, live inputs and any available clips will be displayed to choose from for each box. Again the question mark will become a check mark once the inputs are selected and the parameter is set.

Effect position offset parameters can also be changed. Touching an offset button displays a keyboard for text entry to set the parameter.

Effects do not have to be taken offline to be changed. Any changes to an effect on air will be used the next time the effect is taken to air.
