VideoOverlayConfiguration / VariablesPane

Variables Pane

The variables pane displays, in the form of a tree view, all of the variables that can be assigned to a control.

It is a list of variables that can be assigned to the controls. All of the variables can be categorized into 15 major groups.

  1. Common variables
  2. Maths channels variable
  3. Voltage varibles
  4. Digital variables
  5. GPS variables
  6. Altitude variables
  7. General use variables
  8. Time variables
  9. Angle variables
  10. Pressure variables
  11. Temperature variables
  12. Auxilliary variables
  13. Miscellaneous variables
  14. Lap timing variables
  15. Simulated variables

Assigning variables to controls

To associate a variable with a control - i.e. have the control display that variable - drag the variable from the tree and drop it onto the body of the control.

Variable Properties

Each and every variable has a set of properties. To make alterations to the variables, click on the property that you wish to edit. This will open up a window that is specific to the property that you wish to alter.

The list of properties is as follows:

Advanced options

  • Maximum rate of change
The Maximum rate of change option will allow you to set a value which limits how much the variable can change over one second. This can be disabled by setting the value to zero.


  • Standard
You can select a standard transformation relevant to the selected variable from a drop down list.
  • Custom
You can write an equation that will be used to by the VIDEO4 to convert the native values received from the data logger into the value that is shown on screen.

The independent variable x is used to refer to the present variable.

e.g. If you wish to convert a voltage value to mill volts, you can write the following equation.

Variable Name

This is the name assigned to the variable. Name of any variable can be changed to suit with your requirements.

Smoothed over

This is a smoothing filter that is used to smooth out any peaks and troughs in the data. Smoothing can be disabled by setting this value to zero.
