Resolution is a measure of the number of pixels a video contains both horizontally and vertically. Some common resolutions are 640×480 (SD) 1280×720 (HD), 1920×1080 (HD). Often these are referred to just by their vertical dimension such as 480p, 720p or 1080p.
Resolution in Video Production
Higher resolutions offer more clarity and realism, making them preferred for cinematic releases or commercial advertisements. For instance, if I had to film a commercial for a luxury car brand I would choose a 4K resolution (3840 x 2160 pixels) at a high frame rate to capture all the intricate details of the car’s design, movements and even the finest subtleties, like the gleam of paint or the reflections of the environment.
If the final video will be viewed on small screens like mobile devices or laptops, lower resolution is sufficient. However, if the video will be viewed on larger screens, you will need a higher resolution. The problem is that the higher the resolution, the greater the computing resources needed to process and store the data. On average, editing 4K video takes twice as long as editing FullHD video. As a result, higher resolution video can be more expensive to produce. The price will also be influenced by a more expensive camera and professional software.
Ultimately, the choice of resolution for video production is a trade-off between image quality, computing resources and budget.
Resolution in Photo Production
In photography resolution is measured in megapixels (MP), referring to the total number of pixels in a picture. Each megapixel represents one million pixels, and the higher the megapixel count, the more information the image captures. In commercial photography, a photographer may choose to use a high megapixel count to accurately represent the fine details of a product. This is particularly important for industries such as e-commerce, where customers heavily rely on product images to make purchasing decisions. However, larger file size comes with higher resolutions, which may require more storage space and longer transfer times when sharing files with clients or uploading them to online platforms.
The ‘ideal’ resolution depends on how you intend to use your file. For social media sharing, 8MP or 720p may suffice, while commercial projects may require 4K, 20MP or more.
