Another way is to use the monitor in control panel. Set the ID of the monitor (here 1) to the output of the NDI 5 Watcher. That's it. You can choose the size of the monitor in the control panel as you want. You don't need any extra stage for the preview.

OK, lesson learned - it was a corrupt file at 

/Users/theatre/Library/HTTPStorages/com.troikatronix.isadora

When IT uninstalled and reinstalled Izzy it works on 26.7.1. Live and learn. Thanks all! FAS

As a workaround, can I edit the Isadora preferences file manually while the Isadora application is closed?

 I don't know how to edit the preferences file since it's binary and not plain text, but one workaround is:

Use the steps in this article to install both the newer version of Isadora, and an older version of Isadora that doesn't have this problem.Delete your Isadora Preferences (use the steps under "macOS" and "Windows Option 2" from this article to delete all of them.)Open an older version of Isadora that doesn't have the issue.Change the OSC port in that versionClose the older version of IsadoraOpen the newer version of IsadoraIt will create a new preferences file by copying the older preferences file, in theory taking on the OSC port you set in the old one.

NOTE: If you want to change the port again, you need to perform steps 2-7 above again.

Hi all, 

I'm making a show and trying to use one singular PTZ camera. It's a Cinetreak PT20. This is my first time using one. Right now I'm just in my studio and I've hung it from a pipe and the image seems to be really...bouncy. Like it actually shakes. And it's not after it PTZ's...just stationary. No one else is in the room and I **barely** move when I'm programming (lol). Has anybody experienced this behaivor. I thought it was maybe some kind of setting that was creating an optical illusion of bounce...wrong hz or something, but everything seems right. This is sort of shot in the dark...but it's bouncy to the point of distraction (for me at least). I even bought a piece of hardware that was supposed to absorb vibration, but that made it even worse. I'm sort of at a loss and wonder if I just bought a bad camera. Any thoughts greatly appreciated.
