I searched the forums, knowledge base, guides and Google, but unfortunately had no luck in finding an answer.

We are using vMix for sports stadium perimeter advertising and have been asked to implement a mm:ss countdown to mirror the match timing system, but I can't get the SetCountdown function to set the time via HTTP API to 40 minutes.The method is to grab start/stop/reset events generated by an official's key press on a proprietary system - another project - and use these to trigger a countdown timer appropriately.

e.g. http://127.0.0.1:8088/API/?Function=SetCountdown&Value=40:00&Input=-1 - sound about right? No luck.

It struck me that I couldn't get it working from the shortcuts panel either. Does this make it a bug or am I formatting the request incorrectly?

Version 14.0.0.102

Any help here would be very much appreciated.

My best guess (have not looked into your particular API details) is that your call is not fully URL encoded. Most likely the colon in "40:00" that messes things up. It should be "40%3A00"

For URL encoded strings, see

Good luck!

Could it be that you have to set the full time, days hours minutes seconds ie 00:00:40:00 to make it work?

Have you added a input with a timer?
The last bit of the API request is saying it should affect an input named "-1". Think this means the "Active" input and that's not a good idea för a timer.
Add for example the TimerClock.xaml as an input.
Then the api request for setting the time would be something like this:
http://127.0.0.1:8088/API/?Function=SetCountdown&Input=TimerClock.xaml&SelectedName=txtClock&Value=00:40:00
Starting the clock
http://127.0.0.1:8088/API/?Function=StartCountdown&Input=TimerClock.xaml&SelectedName=txtClock
Pausing the clock
http://127.0.0.1:8088/API/?Function=PauseCountdown&Input=TimerClock.xaml&SelectedName=txtClock
Stopping the clock
http://127.0.0.1:8088/API/?Function=StopCountdown&Input=TimerClock.xaml&SelectedName=txtClock
Hope this helps you...

Hi

SetText if for setting text values only. It has no effect on timers/countdowns.

Check the documentation in order to learn how to use the SetCountdown, AdjustCountdown commands.

No it works perfectly and reliably when you use the appropriate commands for it

To Set countdown to 40:00 and display 40:00 on title.
The following commands must be sent.

Using title Title2Blue.xaml

Changed the Live Field to a countdown.
(As Live is the 3rd Field Index value is 2)
(Index always starts at 0, 1, 2 etc)

1) Set Countdown Field of Live to a countdown timer to 40:00.
(This will NOT set text to display 40:00 on title)

http://127.0.0.1:8088/API/?Function=SetCountdown&&SelectedIndex=2&Value=40%3A00&Input=1

2) Set text of Live to display same as countdown timer to 40:00.
(This will set text to display 40:00 on title)

http://127.0.0.1:8088/API/?Function=SetText&SelectedIndex=2&Value=40%3A00&Input=1

Function=SetCountdown&Value=00:05:00&Input=135

This worked for me but it did not show the new value until after I started the countdown.
