Hi, those are great solutions and I didn't realise Isadora could do that. I have some ideas regarding linking multiple eyes together to lock on to the eye shape and then put a cluedo cutout over with a gaussian mask. Have attempted a couple of versions attached sans eyes prior to this. Obv foreground faces not always more luminant than background and a variety of other problems inherent in a non machine vision approach. ndi fakebg.izzndi fakebg2.izz
Ultimately for our application we're going for zero user requirements so trying to avoid asking the user to do anything. However, it could be possible to gamify this step in the interim as an onboarding... Thanks!
Tried many things like reinstalling Isadora or setting up a new session.
I have run a test patch on MacOS Catalina 10.15.3 for three hours using exclusively MP4 movies as you have in your patch. It ran without indcident. No crashes of Isadora, no crashes of the Background Movie Player. I am awaiting your answers to my questions in the ticket system and will proceed once I hear back from you.
