Hello, i'm looking to make a time-lapse video of my photoshop creations. For this i need to capture static screen, one that won't zoom in and out while i do. This is a nice feature within photoshop, but to be able to use it i need to be able to put this particular screen behind another screen (i have 2 computer screens, 1 to draw, 1 for reference pictures, leaving me one screen short). The problem is: Once i select this secondary photoshop screen it will record, but as soon as i put another screen on top of that (internet or a reference picture for example) it will record that too, something i obviously don't want it to. Is it possible to record only one screen? Even while it's behind another? And if so, how can i do that? Thanks!
