képkockasebességben

Képkockasebességben, often translated as "frame rate," refers to the frequency at which an imaging device produces, captures, or displays consecutive images. In the context of motion pictures and video, it quantifies how many still frames are displayed per second to create the illusion of motion. A higher frame rate generally results in smoother, more fluid motion, while a lower frame rate can appear choppy or stroboscopic.

The standard frame rate for film has historically been 24 frames per second (fps). This rate was established due to a combination of artistic considerations and technical limitations of early cinema equipment. Television broadcasting has utilized different frame rates, such as 25 fps for PAL and SECAM systems and 29.97 fps for NTSC systems, to accommodate broadcast standards and electrical frequencies.

In digital video and modern filmmaking, a wider range of frame rates is commonly employed. Common frame rates include 24 fps for a cinematic look, 30 fps for a broadcast feel, and 60 fps or higher for capturing very fast action or creating slow-motion effects. Higher frame rates like 120 fps or 240 fps are often used in specialized cameras for extreme slow-motion playback, allowing viewers to observe details that would be imperceptible at normal speeds. The choice of frame rate depends on the desired aesthetic, the nature of the content being recorded, and the intended playback medium.
