Happy new year all! What I've trying to do is have a scene or shot to zoom in or out. So to start off, I add a png or mov of a virtual stage, then I add a chroma shot and some videos. I compose them all in 1 shot. For this shot, I have the stage at a wide shot. I then duplicate the same shot, then zoom in (scale up - so I can have a medium shot)) the stage along with the other materials. I tried selecting all the materials and scaled it, but it doesn't scale accordingly. So I have to manually scale (estimate) each material (the stage, chroma and videos). Is there an easier way to do this. I saw this done using Vmix and it seemed more effortless. 

Hope someone can help me out. Thanks!
