Based on your UI, it seems reasonable to assume you are piping camera feed separately to each preset and therefore, causing a great deal of extra work. Manycam should NOT be as taxing as it is - I am on a 8 core i9 Mac and you’re killing the machine.
You should rearchitect Manycam to abstract cameras - perhaps into “looks”
- one place to grab the image
- one place to implement the chromakey
- THEN fed as input to any presets that want that camera look.
I have N presets all using chromakeying - the key should be implemented just once, not N time as it appears to be now.
Thanks
p.s. I do have some track record designing video / imaging software and UIs. At least the Academy of Motion Picture Arts and Sciences thought so as did the Academy of Television Arts and Sciences. I’d like to help you step up ManyCam’s game.
