This script makes from a text source a media countdown timer. Once any media starts playing in the live output, there will be a countdown in the selected text source. You can select this text source in the script properties.
Nice -- I'm happy I didn't have to write it myself :). This will be handy when I'm scheduling a time-lapse video to run in a live broadcast. It looks nice when pointing to a text in a dedicated "faux scene" in a multiview.
