When producing advertising materials for various media, many companies identify the required specifications for each medium and 'resize' accordingly. This involves simply cropping 16:9 horizontal TV footage into a 9:16 vertical format, stretching the background, or changing the position or boldness of the ad copy before hanging it on billboards. This approach is not wrong, and the reason is clear: it stems from production efficiency, driven by the need to maximize exposure across as many media channels as possible within a limited budget.
