Currently using OBSBOT Tiny 4k and had several presets setup. When cycling between them certain ones would Zoom in and Move horizontally ok but it wouldn't go the the vertical position. Or it would go to the horizontal and vertical position and not zoom in.

Has anyone else had this issue? I can't seem to figure out how to get all parameters to be set when selecting one of the presets.
I figure I'm doing something wrong but perhaps I just don't know enough about vMix.

Yes, I can confirm that this is the case, and seems to be a relatively new development... OBSBOT PTZ inputs used to work properly in vMix.

In my testing, with either the OBSBOT Tiny or Tiny 4K, when moving to a PTZ virtual input, if pan tilt and zoom moves are all required, vMix will only do two of the three moves.

This appears to be limited to the way vMix is handling the OBSBOT's UVC PTZ implementation
I don't know if the incompatibility is on the vMix side or on the OBSBOT side.

Notes:
Presets clicked in the OBSBOT Webcam software work properly
vMix PTZ inputs for Insta360 Link cameras (or another brand of UVC PTZ camera that I tested) work properly

All software and firmware versions are up to date.

You don't happen to know what version of vMix they used to work on? Or perhaps it was a change in OBSBOT firmware?

I don’t recall when it started happening… there have been several software and firmware updates in recent months, both vMix and OBSBOT

I just did some testing by reinstalling vMix 25, and the problem persists. Then tried vMix 24, same issue.
So I suspect the problem is on the OBSBOT side of the house.... because this used to work properly.

The most recent firmware release (august 21 2023) for the Obsbot Tiny2 camera has fixed the PTZ issue.
So far, there hasn’t been an update for the Tiny 4K or Tiny cameras, so the issue persists with those models.

And on a related note… the Obsbot Webcam app’s virtual camera either raises an error when creating an input in vMix or crashes vMix entirely.
