What does the term frame size refer to in video?

Frame size in video refers to the dimensions of each individual frame within a video sequence, typically expressed in pixels. This is essentially synonymous with the resolution of the video, which indicates how many pixels are displayed in each frame. For example, a frame size of 1920x1080 denotes a high-definition resolution of 1920 pixels wide by 1080 pixels high.

Understanding frame size is crucial because it affects the visual quality of the video. Higher resolutions imply more detail and clarity, allowing for a better viewing experience. In the context of video production and multimedia practice, knowing how frame size interacts with other elements like bitrate and color depth can influence decisions regarding compression, quality, and file size. Thus, identifying frame size as the resolution is the correct interpretation of the term.
