I want to use jitter to analyze a video of a real-time capture of a browser screen.

I used desktop object. I could capture screen in only MAX. But I couldn't capture webbrowser.

Is there any other good way to capture the browser screen in video?

I have a question about MAX/MSP.

Here on Win 10 jit.desktop grabs everything (with the Help patch), even a second screen when I move the mouse over it.

Maybe it is a conflict of different GPUs being used with Max and the web browser?

 with NDI output enabled, and either the recently released 

another possibility is OBS with NDI output enabled, and either the recently released jit.ndi externals or if on Mac the NDISyphon app.
