For conferences, a frequent request is a countdown timer that can be displayed on a screen for the presenters.
Here’s just such a system in action (Best viewed full screen):
A script cue, that can be copied and pasted, starts a countdown timer on a video display. The countdown time is the post-wait time of the script cue.
When the timer reaches zero it displays a message.
How it works:
The cue that starts the countdown is a script cue
It stops the counter cue if it is running, then sets the notes of the counter cue to its own post wait time. It then starts the counter cue.
The SECS script cue secs sets the time by setting the memo cue VAR to the number of seconds from the value the calling cue stored in the notes of cue count
The Main Loop then starts.
The script cue numbered PROG gets the countdown time from the q name of cue VAR decrements it by 1 and stores it back there.
The time is then formatted by padding single digits and inserting colons
This time is then included in an instruction which sets the custom OSC message of a network cue, which is started to set the text of a title cue to the formatted time
If the time has reached 0 then the title cue is set to the end of countdown message
A start cue then restarts the loop cue.
To ensure all elements of the loop have completed, a short pre-wait is set at the start of the loop. We want the loop to repeat once every second so we set the pre-wait to .1 secs and the pre-wait of the start cue that will restart the loop to .9 secs.
This is not the most compact means of achieving a countdown but it allows all the variables and OSC to be seen working quite clearly, which makes it reasonably easy to customize.
