Within vMix, scripting can only do what shortcuts can do.

And having looked through the Shortcut Function Reference for vMix 27, I don't see a shortcut for this.

There are still many things within vMix that have to be done manually, and this appears to be one of them.

You'll need to make a Feature Request in the Feature Requests forum.

What functions within vMix can a script fire that no shortcut exists for?



That wasn't what they asked.

They asked how they could adjust these sliders in the Colour Key section with a MIDI controller:

Yes, I'm aware that scripting can control things outside of vMix, such as within Windows itself.

There's a reason I specified that I was talking about control within vMix, which is limited to the controls available through shortcuts.

It was a direct response to the OP's question of



when there's no difference between the 2 in this case (or any other when discussing functionality within vMix).

Hi, ... Let me add my 2 cents....if you want to control anything outside f vMix, then go and download PanelBuilder ...do a search in 3rd Party Apps, and it is there...next, before running back and forth here, download the training videos, and watch and follow the instructions carefully...it does everything in vMix, and can be used on a tablet, or another PC, making it completely free from the vMix machine .... I have been using it from the day it was posted here with NO issues...I even created my very own buttons ... check links below ... https://forums.vmix.com/...r--Controller#post111227

Thank you , missed (overlooked) that

Hello yes a midi controller fader can change the colour correction sliders but un-fortunatelly also i dont see something for chroma key. A feature request good to be exist but this will maybe be implemented at best scenario from next year 2025 this season about and vmix 29 and up.
Until then it can be done but not directly by using the midi controller in vmix. But if you use bitfocus companion with vmix module and midi module is possible to be done by using triggers. Yes it is need to be done manually point to point,but possible. For more auto way i believe central control may offer it
Im attaching a picture from my bitfocus companion using for audio my akai apc mini i use for my headphones
The maximum value that can take a fader in the akai is 127. So we make a trigger "variable to watch" the midi device via the midi module and for example we set for the fader that is called 1_56_ when it have value 127 to go the volume to 100 by using the vmix api shortcuts
Then another trigger for example when we set a little down the fader it will be value 117 and we change the volume to be 90 and so on until value midi fader to be 0
For colour correction if you see here https://vmixapi.com/?function=SetCCHue for example it takes values from -1 to 1. So at 127 in the trigger we can set it to -1 at 117 to 0.9 and so on
This i believe can work for every value that work same way for colour correction in vmix. For the companion midi module you can see more https://www.youtube.com/@Remotely-Possible and more about the idea per trigger this video
Central control https://centralcontrol.io/ i believe that may have a a more automated way for this kind of workflow.
