I love the idea of B-roll above the head of the speaker. BUT, is there a possibility of "sizing down" the speaker (the A roll?) lets say, to not be the highlight of the video (for some of us who maybe want to put more emphasis on the B-rolls. Because sometimes the usual right lower side or left lower side or even center lower part is the one preferred by the speaker, like in some shorts that highlight a product or an image or some bullet points or checklist on a B-roll. Will that be possible (like as an optional setting).
