Focus on monitor. Closeup of writing a text on paper. In the picture you can see the focus monitor in the office standing on a wooden table, as we see the hand of a young man out of focus and the fact that she takes notes on paper. Perhaps he is a writer, or simply makes notes in a notebook, it is possible the text of the designer, an accountant, or a person working next to a computer screen. You can replace green screen with the footage or picture you want. You can do it with Keying effect in Adobe After Effects , check out tutorials on YouTube.
