Please excuse any typing errors during the translation from our German vMix WIKI page.

Scripting only works with the 4K or PRO version. Some examples and tricks for the scripts in this post are from “doggy's” SCRIPTING FOR DUMMIES SCRIPTING FOR DUMMIES and other posts from the vMix forum.

Scripting is possible within vMix using the built-in editor or as an external command via browser. The collection of examples is incomplete. In the appendix it has a listing from a few of the currently known API commands. vMix Scripting supports Web scripting and VB.NET when writing your script. All variables are local, from version 24 there are dynamic variables and dynamic inputs, which could be called public variables. But their use is a bit cryptic. But you can easily use text fields of an unused title input as pubic variables. The input can be either the filename of the title (case sensitive) or the input number.

In the beginning, the vMix Script Builder (an external utility) is an indispensable help. It creates scripts with the correct syntax, selection via pulldown menus.

AVOID SPACE IN SCRIPTNAMES

A script can be called via a shortcut.

there are 4 different ways to write a script. In the end the variants all do the same. Normally the simplest variant is sufficient in vMix Editor. (WEB)

–VB.net     can handle variables, WEB cannot.
–API     corresponds to VB net
–WEB     without variables, short and simple, sufficient for most internal scripts.
–HTTP     sends the API command via browser or external software.

Both AudioBusOFF and audiobussoff work.
ACHTUNG: Titles and text fields are case sensitive:
Title 0- The Classic Blue.gtzip is exactly what the title is called. The script does not work if the upper/lower case is changed.

This example writes “Some Text” into a specific text field of a specific title.
Instead of the title name, the input number can also be specified, instead of the text field, its index number.

WEB

Function=SetText&Input=1&SelectedIndex=0&Value=Some Text

VB.NET API

   API.Function("SetText",Input:="1",SelectedName:="Headline.Text",Value:="Some Text")

VB.NET

Input.Find("Title 0- The Classic Blue.gtzip").Text("Headline.Text")= "Some Text"

HTTP get

http://127.0.0.1:8088/api/?Function=SetText&Input=Title 0- The Classic Blue.gtzip&SelectedName=Headline.Text&Value=Some Text

This will return all available data from the API (Application Programming Interface) of vMix as XML. (Put the following command line in your browser, vmix has to run on the same machine)

http://127.0.0.1:8088/api/?

Be careful when using web addresses with symbols like , # etc., as these must be correctly “encoded” to work as a url value. This is not only the case with vMix, but with all web-based APIs. This is a handy tool that can be used to code the values correctly: URL Decoder/Encoder

Enter only the text you want to set as a value, not the whole url. This would make

Excel/CSV,Sheet1,5

become the following

Excel%2FCSV%2CSheet1%2C5

And the whole URL again would be:

http://localhost:8088/API/?Function=DataSourceSelectRow&Value=Excel%2FCSV%2CSheet1%2C5

This example uses the supplied title NewsHD and writes Hello World in the field Headline

Input.Find("NewsHD.xaml").Text("Headline") = "Hello World!"

or to put it another way:

dim i = Input.Find("NewsHD.xaml")
i.Text("Headline") = "Hello World!"

route INPUT 4 Video to OUTPUT

Function=Activeinput&Input=4
or
Function=Cutdirect&Input=4
or
http://127.0.0.1:8088/API/?Function=Cutdirect&Input=4
or
API.Function("Cutdirect",4,) 

route INPUT 3 Video to Preview

Function=Previewinput&Input=4

route INPUT 1 Video to OUTPUT2 routen

Function=SetOutput2&Input=1&Value=1

Route input with a specific name onto the OUTPUT

Input.Find("YourInput").Function("Cut")

Cut cuts INPUT4 to the OUTPUT and changes the previous input to Preview, Cudirect leaves the preselected Preview input.

API.Function("Cut",4,) 

or

API.Function("Cutdirect",4,) 

API.Function("PreviewInput",4,) 

Mix 0 = PGM
MIX 1-3 = Input Mixes, only available on the 4K/Pro versions.
-1 = PREVIEW

fade Preview to PGM

API.Function("Fade",Input:=-1,Mix:=1) 

cut Input 2 to PGM

API.Function("Fade",Input:=2,Mix:=1) 

All these functions create a new input

Title Input from a specific directory

http://127.0.0.1:8088/API/?Function=AddInput&Value=Xaml|C:\VMIX\Name.gtzip

Video Input from a specific directory

http://127.0.0.1:8088/API/?Function=AddInput&Value=Video|c:\path\to\video.avi

Image Input from a specific directory

http://127.0.0.1:8088/API/?Function=AddInput&Value=Image|c:\path\to\image.jpg

Picture Folder Input from a specific directory

http://127.0.0.1:8088/API/?Function=AddInput&Value=Photos|c:\path\to\folder

Video Playlist (m3u)Input from a specific directory

http://127.0.0.1:8088/API/?Function=AddInput&Value=VideoList|c:\path\to\playlist.m3u

Audio file Input from a specific directory

http://127.0.0.1:8088/API/?Function=AddInput&Value=AudioFile|c:\path\to\audio.wav

Powerpoint Input Input from a specific directory
(From my experience, only slides without videos or audios or media files are not played)

http://127.0.0.1:8088/API/?Function=AddInput&Value=PowerPoint|c:\path\to\powerpoint.pptx

Color Input (RGB Farbwert)

http://127.0.0.1:8088/API/?Function=AddInput&Value=Colour|%23FF5733

this allows two inputs to be swapped back and forth, e.g. via the space bar. The input name of the first input serves as the query

if word = "DeckLink Duo (1) 1" then
API.Function("MoveInput",Input:="DeckLink Duo (1) 1" , Value:=2)
else
API.Function("MoveInput",Input:="DeckLink Duo (1) 1" , Value:=1)
end if

Switch on Audio bus of source 1 (green loudspeaker)

Function=AudioON&Input=1
or
API.Function("AudioON",1,)

Route audio bus of source 1 to audio output D

Function=AudioBusON&Input=1&Value=D
oder
API.Function("AudioBusOff",2,"A")

Route audio bus of source 2 to audio output master

Function=AudioBusON&Input=2&Value=M

Route audio bus of source 1 away from the master

Function=AudioBusOFF&Input=1&Value=Master

Route audio bus of source 3 away from the D

Function=AudioBusOFF&Input=1&Value=D

Switch off audio follow video from input 1

Function=AudioAutoOff&Input=1

This script reads the current title of a playlist and writes it formatted into a field of a title.

In this example I use the title “ Title 33- On the shelf- Peach.gtzip ” contained in vMix and write the text into the field “Headline.Text”. My list input is Input2. Please adapt this (title, field and list input number) for your project.

I use a list of MP3 audio files. These are named as follows:
Anni Piper - Two's Company - 01 - Blues Before Sunrise.mp3
Anni Piper - Two's Company - 02 - Live To Play.mp3
Anni Piper - Two's Company - 03 - Man's Woman.mp3

The goal is to extract a usable name from this string.

The finished script looks like this:

'script playing now

dim x as new system.xml.xmldocument
x.loadxml(xml)
dim word as string = x.SelectSingleNode("//input[@number=[h]'2'[/h]]/@title").Value

dim wordArr as String() = word.Split("-")
Dim result0 as String = wordArr(0)
Dim result1 as String = wordArr(1)
Dim result2 as String = wordArr(2)
Dim result3 as String = wordArr(3)
Dim result4 as String = wordArr(4)

Since in vMix coloured rectangles of a title cannot be recoloured*, but text can, I use the ARIAL ASCII character U 2588, Full Block █. The colour of the text character can be easily adjusted
*this is changed in vMix Version 25. In this version you can also change colors from drawed rectangles, created in GT Title.

vMix sometimes makes something “different” out of a number that comes from a data source.
100.00 becomes 100
100.10 becomes 100.1
etc.
However, if the display 100.00 is always desired, this can be corrected via a looping script. In this example it is the title mytitle and the field Headline.Text.

do
dim j as integer
dim i As string = ""
dim mystring as string = ""

i  = Input.Find("mytitle").Text("Headline.Text") 
j = CInt(i)

myString = String.Format("{0:00}", j)

ATTENTION: calling a script from a script takes time. So always set a sleep(200) after a more complex action.

This example switches Input1 on/off to Overlay1 on the computer with the IP 192.168.10.10.

Starts an external programm from vMix and continues to execute the script when the external application is closed.
For example, a more complex external programme can be executed that would be difficult or impossible to solve with vMix Script.

P = Process.Start("notepad.exe")
P.WaitForExit()

This vMix script backs up all active scripts in vMix as individual text files to a predefined folder.
This can be used to make a backup of the scripts in use. This function is not provided in vMix. You can only export all scripts and shotcuts as a whole. When importing an existing export, any scripts added later will be deleted.
IMPORTANT, after an update the path must be adapted to the new version!

Unfortunately, vMix does not allow simple public variables. A variable is only functional in the script and cannot be used by another script. Since writing to and reading from a title is quite fast, you can misuse it as a variable repository. The title is simply loaded at the end of the project and then forgotten. An example title here variablen.gtzip

Always write variables in the title, even integers, as strings in quotation marks! If an integer value has to be converted into a string, this is done with cstr()

Input.Find("variablen.gtzip").Text("i1.Text")="111"
Input.Find("variablen.gtzip").Text("i2.Text")="222"
Input.Find("variablen.gtzip").Text("s1.Text")="anything significant"

Reads variables from the title. When reading out, a string is always created; if this contains a numerical value, the string must then be converted into an integer value, cint().

dim var1 as string = Input.Find("variablen.gtzip").Text("i1.Text")
dim var2 as string = Input.Find("variablen.gtzip").Text("i2.Text")
dim i1 as integer = cint(var1)
dim i2 as integer = cint(var2)

' console.writeline is for test purpose only
console.writeline(i1)
console.writeline(i2)
console.writeline(i1+i2)

   Next

The gtzip template has ONE bar, consisting of 579 individual text fields (hard work , each 3 pixels wide, each with the Arial “full block” characterl █

Load the GT-Title growingbars1.gtzip into vMix.download growingbar1.gtzip
Adjust the size and position of the first bar with the position sliders of this input.
Create 3 virtual copies of this bar.
Move these additional bars to the correct position in each INPUT, using the position sliders.

(IMPORTANT) Rename the 3 copies to
growingbars2.gtzip
growingbars3.gtzip
growingbars4.gtzip

Lade einen transparenten Color-Input. Füge die 4 growingbar-Titel in den Multiviewer ein.
Dieser Eingang ist dann dein fertiges Overlay-Signal.

Damit sich die Balken bewegen, werden 2 Skripte benötigt.
eines, um die Balken zu löschen
eines, um die Balken wachsen zu lassen

Load a transparent colour input.
select the 4 growingbar titles into the multiviewer.
This input is then your finished overlay signal.

For the bars to move, 2 scripts are needed.
one to erase the bars
one to make the bars grow

The scripts are loaded with the preset.
For testing please put the files on the desktop.
-Projekt growingbars.vmix
-GT Titel growingbar1.gtzip

In the script growingbars all necessary variables can be changed.
(colour, transparency of the bar, speed, percentages)
The script is designed for a sum of 100%.

The bar width is automatically adjusted, i.e. the participant with the highest percentage receives the full bar width.\

C deletes the bar
G starts the bar

It is sometimes a bit confusing/tricky to find the right xpath to retrieve certain data from an XML file, be it within a script or in the XML data source manager. A few helpful links that can generate an xpath for you. However, you may need to adjust the results a bit depending on whether you use it in a script or in a data source manager.

http://xmltoolbox.appspot.com/xpath_generator.html (returns a result based on a selection)
https://www.easycodeforall.com/XPathUtility.jsp (outputs a whole list of possible xpaths, also has a few other goodies)

With Datasource, text fields of a title can be coupled with external data. The following function as data:
-Excel -Google Sheet -JSON -RSS -Text -XML

Since vMix makes its API data available as XML, the Datasource Manager of vMix can of course also read and evaluate its own data. To do this, open a title input and right-click in the small title field. Demo title here: datasource_demo.gtzip

e.g. vmix API,  http://127.0.0.1:8088/api/?,  and a valid XML node such as //inputs//input[@audiobusses]

then, press OK.


6. This should then look like this:


7. After that, the individual data can be assigned to any text fields in the title.


Note: data only comes if something is written to the XML. If none of the inputs has audio, the node in the example will simply get NOTHING.

In the example, the Google Sheet is called “Women's Football Google Sheet” and the table “Servette.\\” If you now link title data with selected row, a row of the table can be selected via API. A table can be scrolled through like this.

API.Function("DataSourceSelectRow",Value:="Frauenfussball Google Sheet,Servette,2")

shows, until the script is stopped by hand, every 5 seconds one of 10 rows from a table Google Sheet “Women's Football Google Sheet” and the table “Results”.

while (true)
For i As Integer = 1 to 10
API.Function("DataSourceSelectRow",Value:="Frauenfussball Google Sheet,Resultate," &i)
    Sleep(5000)
Next
end while

RTMP Stream URL for stream1
(Stream2 “Input:=2”, Stream 3 “Input:=3”)

API.Function("StreamingSetURL","Input=1", "rtmp://x.xx123456.i.akamaientrypoint.net/EntryPoint")

Streamkey

API.Function("StreamingSetKey","Input:=1", "2222oioioi23456")

OPTIONAL

User

API.Function("StreamingSetUsername","Input:=1", "USER99")

Password

API.Function("StreamingSetPassword","Input:=1", "123456")

Request streaming status via API and write the value in a title input as a display. An example title from the GT Library is selected as the title. Title 0- The Classic Blue.gtzip

dim isstreaming as string = ""

' do while true/loop,checks continuously until the script is stopped
do while true

   dim xml as string = API.XML()
   dim x as new system.xml.xmldocument
   x.loadxml(xml)

' are we streaming?
   isstreaming = (x.SelectSingleNode("/vmix/streaming[1]").InnerText)
  
' write an answer in a title and change the colour accordingly
if isstreaming = true
  API.Function("SetText",Input:="Title 0- The Classic Blue.gtzip",SelectedName:="Headline.Text",Value:="Streaming is running")
  API.Function("SetTextColour",Input:="Title 0- The Classic Blue.gtzip",SelectedName:="Headline.Text",Value:="red")
else
  API.Function("SetText",Input:="Title 0- The Classic Blue.gtzip",SelectedName:="Headline.Text",Value:="Streaming is stopped")
  API.Function("SetTextColour",Input:="Title 0- The Classic Blue.gtzip",SelectedName:="Headline.Text",Value:="green")
end if

sleep(500)
loop

zoom

API.Function("SetZoom",Input:="1",Value:="0.5") 

tilt

API.Function("SetPanX",Input:="1",Value:="0.5") 

API.Function("SetPanY",Input:="1",Value:="0.5") 

This requires a script and a web browser input in EVERY project. When the project is started, the website is called once. Since a vMix API command can also be sent via the web browser, this command triggers the script.

The web browser INPUT has the following URL:

http://127.0.0.1:8088/api/?Function=ScriptStart&Value=startexternal

The following script with the name “startexternal” must be present on the computer:

API.Function("StartExternal")
sleep (1000)
API.Function("StopExternal")
sleep (1000)
API.Function("StartExternal")

With this trick, almost any function can be executed as an Autostart command.
