Yes, these are Globals to the active instance of Javascript. The Javascript actor does not have a built in method of sharing globals between actor instances. 
You can bridge this by outputting values to a Set Global Values actor, and feeding the value into another Javascript actor via the Get Global Values actor. This works well when you want to share values primarily in one direction.

I updated my file and User Actors to make them even easier to use python-rename-scene-after-media-v3-2025-08-19-4.1.3.zip

I have one more question about the memory management of the JavaScript actor. What about variables that are created outside the main function? I would assume that these are only available to the actor instance.

 @liminal_andy Didn't you have a method for passing global values between JavaScript actors?

@DusX and @Woland thank you very much for your very detailed feedback and also for create this 8 Notes on and Off Watcher. 

This helped me a lot to better understand how Izadora works, especially when it comes to data flow and actor execution.

I was able to use the actor as a basis and adapt it to my needs. I change it from 8 to 12 Notes and reduce it only the pitch and note on / off information which i combined to a On/Off integer because i only need to track the current pressed notes.

Thank you very much.

Thanks will check it out

Feel free to let me know if you have any issues with it. It should be easy enough to fix since the actions I'm performing are independent from each other and not very complex.

@skulpture

It's basically just taking the file name from the Get Media File Name actor, then doing the equivalent of these keystrokes:

1. Cmd+c (copy)
2. Cmd+r (rename scene)
3. Cmd+v (paste)
4. Enter (confirm Scene Name)

@woland Thanks will check it out - that's pretty advanced stuff. Cheers.

@skulpture

Here's a Pythoner file that does exactly that. It can take a media file name and rename a scene after the file name.

I tested it only on macOS, so you'd need to test it on Windows, but it should have code to handle working on Windows already. The script is not too complex, so it should be fine.

Theoretically you could do it automatically using the Get Media File Name actor to feed the text into a Pythoner actor that then keystrokes the keyboard shortcut for rename Scene then pastes the file name into the Scene name.

@dusx A client project. Nothing too fancy - but all under NDA. I basically have 59+ images in my media bin and I was wanting to rename the scenes to the images that take up the whole screen/ouput so I can keep track of everything.
