Hello,

Our church has been using vMix to livestream for roughly 2 years, and it has worked great thus far. For context, we have been using PTZOptics NDI cameras with 0 hitches thus far.

Recently, we upgraded a non-NDI camera to a Birddog P100. The NDI signal/picture quality is superb, but there has been an issue with the PTZ presets in vMix. Specifically, (on only the P100), when previewing a saved PTZ preset (the "Create Input at this Position" presets, that is), it will update ZOOM and HORIZONTAL positioning from that preset, but does not move to the correct VERTICAL positioning. Instead, it will always go to the "home" position (straight out/in the middle). Again, zoom and horizontal movement DOES work correctly when selecting vMix presets.

Some extra details:
-We are using the newest vMix 24.0.0.72 (the issue seems to exist on vMix 23 and previous versions of vMix 24)
-The PTZOptics cameras are/have remained working properly.
-The camera is using a static IP and is using the recommended "Sony VISCA over IP" device type for PTZ control in vMix. Further, vMix connects successfully and DOES allow every axis of movement through vMix's built in PTZ control. (Again, though, changing to any preset will set the vertical position to default).

Some things I've tried:
-Changing to previous versions of vMix (23 and an earlier version of 24)
-the easy fixes (restarting every machine, camera, network, vMix, etc.)
-Checking the birddog Camera itself. It is currently using UDP for the NDI signal, though TCP is the default and also did not fix the issue.
-Relatedly, using Birddog's built-in "Control" through their web interface (via the camera's IP address), DOES work as you'd expect. You can save "presets" and recall them without any strange behavior with the vertical axis. Screenshot 2021-12-15 153925.png (68kb) downloaded 0 time(s).

I could really use some extra brains, if anyone has any leads as to what an issue may be that causes such a strange type of "bug." I'm unsure if this is a birddog thing, a vMix thing, or a user-error thing. But whichever way, I could really use a hand. Of course, I'm glad to give any details if necessary.

A thank you to the vMix team and you fine people on the forum - your discussions have helped me troubleshoot many issues many times.

Thanks,

(edit: changed description to match followup post below)

In the BirdDog GUI, disable the save preset settings.

A quick update to add info and hopefully a bump.

I went through the on-screen display on the p100 and DISABLED an option in "System" called "Preset Memory" - but this also did not fix the issue, even after a restart and reverification of both the p100 and vMix's settings. I believe this was what Ask was mentioning in the above post.

I'm still pretty much out of ideas, apart from factory resetting everything (again) and rolling back the firmware (again). As always, any input or suggestions are greatly appreciated!

Thanks
