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

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.
