Formula for QF "Frame Quality"

[53x11]

Does anyone know the forumla that some programs (gspot) use to calculate QF "Frame Quality?"

It is usually described as 0.XXX bits/pixel.

:thanks:

Formula is:

(video bitrate in bits/second) / (horizontal res * vertical res * framerate)

For example, an xvid with an average video bitrate of 1000kbit, a resolution of 640x360, and a framerate of 23.976 would yield:

(1000 * 1000) / (640 * 360 * 23.976) == 0.181 bits/pixel

Thanks, the formula works perfectly!
