6. Resize the overlay text box using the padding settings.
The handles on the corner of the overlay text box are not click-and-drag and do not
resize the text box. To resize the text box, use the padding fields to add space above,
below, and on either side of the text.
7. In the layout editing area, click and drag to move the overlay text box or enter values in the manual
position value fields along the side and bottom of the layout area.
8. Click Save.
Custom system variables for text overlays
Using HTTP APIs, you can create your own custom system variables for use in text overlays. Pearl devices also
support RS-232 APIs. This is useful to add custom overlay text that changes throughout the course of your live
stream or recorded program.
For example, using the HTTP API you can create a system variable for the current GPS co-ordinates, then use a
script to update the GPS co-ordinates in your custom variable as the physical location in your stream changes.
Here's an example custom variable called gpsvar1 that has a value of N103 68201 W765 29712 . To insert the
custom system variable into a text overlay, simply type %(gpsvar1) into the Text field.
