Frames in a video are a sequence of bitmap images that are all displayed one after the other in rapid succession. To the human eye, they are viewed as a seamless whole which creates the illusion of movement.
Generally speaking, a typical frame rate (the number of frames that are displayed in a given time) used in video production is 30 Fps (frames per second), which means there are 30 bitmap images presented in one second of video footage.
Imagine this — A single frame in an HD (1920 x 1080p) video sequence is composed of 2,073,600 pixels. When presented one after the other in rapid succession, one second of HD video footage at 30 Fps contains precisely 62,208,000 pixels.
That’s a lot of pixels for just one second of footage! What’s even more unfathomable is how much care and attention we need to ensure that that one-minute video footage is pixel-perfect!
