Final answer:
In a movie, the number of pixels determines resolution, frames per second affect motion, and lumens determine brightness.
Step-by-step explanation:
In a movie projected on a film, the number of pixels determines the resolution and clarity of the images displayed. Each pixel represents a small area on the screen and contributes to the overall picture quality. Additionally, the number of frames processed per second affects the smoothness and fluidity of the motion in the movie. The higher the frame rate, the more detailed and realistic the motion appears. Lumens, on the other hand, determine the brightness of the movie when projected on a screen. The higher the number of lumens, the brighter the image.
