Bits / Pixel × Frame

Bits/(Pixel*Frame), сокр. bpf
биты на (пиксель × кадры)
♦ The one factor that will give you a good idea of video quality, regardless of height/width/framerate/depth, is bits/pixel*frame or bpf. This is a composite measurement which includes the codec settings, frame size and framerate.
♦ In general, assuming your codec is AVC or MPEG-4 ASP (Xvid/Divx), a bpf of 0.1 or more is good, 0.2 or more is very good, and 0.3 or more is excellent. This holds true for most real-life moving video, and less true for pure animations.
