Using MOGRT to make checkbox selections in Premiere Pro Extendscript

While developing a Premiere Pro Panel using Adobe Extendscript, I encountered an issue with importing a MOGRT file and setting slider values. The code snippet used for this task is as follows:

var transition = app.project.activeSequence.importMGTFromLibrary("WARATAH TV", "WARATAH TV 2019-20 TRANSITION", (myStartTime - 0.55), 2, 2);

transition.setSelected(true);

var components = transition.getMGTComponent();

components.properties.getParamForDisplayName("Slider Value").setValue(5);

However, when attempting to manipulate checkbox values in the imported MOGRT, the same code does not produce the desired results.

components.properties.getParamForDisplayName("Checkbox Value").setValue(false);

Any insights on why this might be happening or suggestions on how to interact with checkboxes within the MOGRT?

Answer №1

You may have overlooked including the second parameter 'boolUpdateUI'...

setValue componentParam.setValue(newValue, boolUpdateUI)

Explanation

Retrieves the value from the component parameter stream. Please note that this function is only applicable to parameters that are not time-varying.

Arguments

The newValue should match the type required by the component parameter stream. Setting boolUpdateUI to 1 will prompt Premiere Pro to update its user interface after modifying the stream's value.

Output

A return value of 0 indicates a successful operation.
