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.

Try putting another camera (any camera) up on the same pipe to see if it has a bouncy image as well.

What is upstairs from you? If it's something like heavy machinery or a dance studio, that could make your ceiling shake.

Hello,

Edit: related to this issue?

I am finding that when I preload a scene that contains a Movie Player actor, the movie file immediately begins to play but with the video hidden (e.g. I can hear the audio begin playing, but nothing is sent to the projector), even though the scene has not yet been activated. When I subsequently activate the preloaded scene: (1) the video becomes visible on the stage, and the audio continues in sync with the video; and (2) I can see that the position output parameter of the Movie Player is not zero (e.g. it began playing when I preloaded the scene earlier, not when I just activated the scene).

This is happening only on my Windows laptop. It works as it should on my old Mac laptop (quite old version of Isadora). I don't remember this happening before I just updated to Isadora 4.5.1.

This happens on my Windows laptop even when I create a new, blank Isadora document and add the following three actors:

Scene 1:
[Preload Scene] actor 

Scene 2:
[Movie Player] -> [Projector]

The only workaround I can find is to not preload scenes, but this is a problem for my application which requires intricate cueing.

Isadora 4.5.1, Windows 11, Intel i7-13700H. H264 file with stereo audio track.

Many thanks in advance for any advice.

Jonathan.
