We want to check just how imperceptible our video converting operation went, therefore we need a
system to check frame by frame the similarity or differences. The most common algorithm used for
this is the PSNR (aka **Peak signal-to-noise ratio**). The simplest definition of this starts out
from the *mean squad error*. Let there be two images: I1 and I2; with a two dimensional size i and
from the *mean squared error*. Let there be two images: I1 and I2; with a two dimensional size i and
j, composed of c number of channels.
\f[MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2}\f]
