What term describes the number of still images played per second to create the illusion of movement?

The term that describes the number of still images played per second to create the illusion of movement is frame rate. Frame rate is crucial in both film and digital media, as it determines how smooth the motion appears to the viewer. Typically measured in frames per second (fps), a higher frame rate means more images are displayed in a second, resulting in smoother motion, which is particularly important in action scenes or fast-paced video content. For instance, a standard frame rate in cinema is 24 fps, while video games often use frame rates of 30 fps, 60 fps, or even higher for enhanced fluidity.

Bitrate, on the other hand, refers to the amount of data processed per unit of time in a media file and relates more to the quality and size of the video rather than the smoothness of the motion. Resolution deals with the detail an image holds and is expressed in terms of pixels (e.g., 1920x1080), indicating how sharp the image is but not directly affecting the illusion of movement. Refresh rate pertains to how often a display updates its image per second, which is important for monitors but does not signify the number of still images in a video sequence. Thus, frame rate is the most accurate term for
