I have a new client looking for advertising on a custom screen size (4 meters x 7 meters) down the side of his new building. My question is how would i edited a video screen size like that. What is the resolution size I have to set in the editing software to fit that size. Do i have to set it up to match that screen size in After Effects. Because the px size is a very large size. Or is there a converter that takes the minimum and makes it large to fit the screen..
