Make sure you have the “switch blue and red” set up properly!.It might be tricky since I don’t think Krita tells you which window is which… But you can always change it to the other one. In OBS (or your screen recorder of choice) add a new source that will capture the window: in OBS go to “Image source” which is between “Scenes” and “Sound mixer”, click the + button, select “Window Capture”, then name it somehow, like - “Krita Window Capture”, then select the proper window.In the other window, position your image the way you want it to be seen in the result video. In the window you’ll be using for painting, make sure to rotate/zoom the image so you know which window is which in the next step.Go to Window -> New Window, and in that new window go to Window -> New View.OBS and Kdenlive are both free and open source, just like Krita. Here I share a trick to achieve this with Krita, OBS (or any other screen recorder) and Kdenlive (or any other video editor). One of the advantages is that no matter how you zoom or rotate, the image will be still, so no matter how much you speed it up, your viewers won’t get nauseous from all the blinking. I bet lots of you have thought about that, how awesome it would be to have Krita record strokes like Procreate and then just make a simple quick timelapse. TL DR: Create new view inside a new window, put window behind the one you’re painting on, make OBS record the window instead of the whole screen.

You can already test it in Krita Next but beware of resources trouble (best way to behave is to not modify resources on Krita Next yet). So, good for timelapses, worse for tutorials and stuff. Update: In Krita 5.0.0, there will be a new Recorder docker that will do exactly that, but with less trouble (and you don’t need to rely on OBS), except that it won’t record sound and it won’t record during strokes.
