The term resolution refers to the sharpness and clarity of an image. It is determined by the number of pixels in an image and the quality of those pixels. The higher the resolution, the sharper and more detailed the image will appear.
Resolution impacts the overall look and feel of a video. A higher resolution results in a more visually stunning image, while a lower resolution can result in a less clear, grainy image.
In filmmaking and video production, common resolutions include 1080p, 720p, and 4K. 1080p refers to a resolution of 1920×1080 pixels, 720p refers to a resolution of 1280×720 pixels, and 4K refers to a resolution of 4096×2160 pixels.
The resolution of a video is determined by the camera used to shoot it and can also be adjusted in post-production using software such as Adobe Premiere Pro or Final Cut Pro. It is important to choose a resolution that is suitable for the intended viewing platform and audience. For example, a 4K resolution may be overkill for a video that will only be watched on a smartphone, but it may be necessary for a film that will be shown in a movie theater.
