DusX and Woland, thank you very much for your help and useful recommendations!

A special thanks to DusX for suggesting that we bundle parameters into JSON and for sharing the guide to JSON Bundler and JSON Parser. This really helped us understand how to reduce the number of inputs and outputs and simplify the connections in our project.

Woland, thank you for testing this in Isadora 3.2.6 and for suggesting the additional options using Broadcaster / Listener and Set / Get Global Values.

Regarding our statement about previous versions — we were mistaken. Thank you for checking and correcting us!

We really appreciate your responsiveness and the time you took to help. Your advice has genuinely helped us move forward!

 Thanks. I'll see if I can fix this for macOS this week.
Is the Load Cube actor with the python working for you once you enter a filepath?

What macOS version are you running?

 I'm on Sequoia 15.7.9

Wonderful, without the file selector it works perfectly. Thank you!

when I select a .cube file from my hard drive, it doesn’t display a file path, but “file not selected,”.

 OK, the file selector actor isn't working on your system.
I will have to move my project over to my mac and do some testing to fix this.
What macOS version are you running?

You will need to disconnect it from the load Cube for Color Grading actor, and provide the full file path for the cube file for the 'cube_path' input, including the file extension.

Hi, thanks for the quick answer

DX - PY - Browse for File (win+mac) :

1. it offers me to select a file from my hard drive
2. when I select a .cube file from my hard drive, it doesn’t display a file path, but “file not selected,”.

DX - PY - Load .Cube for Color Grading :

1. Status doesn’t change. It says “LUT file not found”

There is no red hazard on the Python actor.

Help/Open Plugin: It points to the virtual environment i. my project folder that I set up for this project. (LUT test….)

You should be able to use the Syphon output from stage setup to allow OBS to grab the input. 
Using OBS is a good choice for big video like this, it allows completely separate cpu/gpu processes to deal with the video recording, which will ensure Isadora provides the best possible playback
Yes, set OBS to record at the speed you set the Isadora framerate at.
Since you are on Mac you could try Syphon recorder, it may be the easiest option. Syphon Recorder | Syphon

Ok, I need sleep, Im going by train tomorrow to the festival where I need to test the work tomorrow night. Help is much appreciated, thanks !!!!

I changed the framerate today - can that make a difference? Its the only thing I did different from earlier

@dusx

I just retried with apple pro res and quicktime. Its all black

@dusx

I changed the framerate - Is that the same framerate that will show in OBS? If I can possibly record there in stead?
