Hi everyone,

I'm experiencing an issue with PTZ shortcut functions in vMix and wanted to check if anyone else has encountered this.

I use PTZ shortcuts mapped to an Xbox controller for camera control.

In **vMix version 24.0.0.72**, all PTZ functions appear correctly in the shortcut list (Move, Zoom, Focus, Stop, etc.), and everything works as expected.

However, in **vMix version 28.0.0.42**, many of these functions do not appear correctly and instead show up as:

const_647
const_650
const_653
const_655
const_656
...and others.

Because of this, it's impossible to clearly identify which function is being assigned, which essentially breaks my workflow.

### What I’ve tried:

* Restarting vMix
* Creating a new preset
* Reinstalling vMix
* Checking specifically the PTZ category

### Expected behavior:

All PTZ functions should appear with their proper names (as in vMix 24), not as internal "const_xxx" values.

### Questions:

Is this a known bug in vMix 28?
Is there any fix, workaround, or update that resolves this?

Thanks in advance for any help.

Most likely a pirated copy of vMix as this is simply not possible with an authorised copy.

You can reach out to vMix Support directly to verify this:
