Is there any way for vMix to send a VISCA command to set absolute coordinates?
It exists in the protocol, but is there any way to channel it through a vMix script?


EDIT:

I thought I could work around the whole thing by writing my own program to handle the PTZ control — and it works.
But I also want to use vMix’s fantastic integration, yet we can’t have two connections to the camera.
So I figured I’d relay vMix’s control through my program on (127.0.0.1) localhost, but then I’d need to set a port number, which vMix doesn’t support.
So I’m back to square one :-)

The problem is that the vMix Script engine only supports a selection of Visca commands.
The command I want to use does not seem to be supported in vMix.

Glad you asked! vMix has excellent support for PTZ, but not all the way.

vMix is designed to work with a joystick, sending a command to the camera indicating which direction it should move, and then a stop command when the joystick is released.

However, VISCA over IP supports a few additional commands, including the ability to send absolute position coordinates. By using the Stream Deck Plus, which features four rotary encoders, I can increase or decrease a value in my software to control the camera position.

This allows for very precise adjustments to the camera's position.

Since the camera only allows one IP connection at a time, I need to relay the control commands through vMix in order to make this function work.

So I still intend to use presets in vMix, but I get a much better sense of control by adjusting the camera’s position using the rotary dials instead of a joystick.

Turning the knobs gives me a more precise and tactile feel when fine-tuning the camera's pan, tilt, and zoom — something that's harder to achieve with a joystick alone.

Could you not still accomplish the same thing using Companion's visca module to send movement commands? I used to do that a fair amount and it worked fine. In other words, Companion tells the camera to move left x amount every time you turn the encoder left by one tick, as opposed to using coordinates. To gain back the ability to change how quickly the camera moves, you could either use variables as the value and change those variables with a knob or buttons, or you could also create a few different pages, like a fast, medium, and slow page, where each page uses different speeds for the camera control
