The values given in MB are approximate for 8-bit data and vary according to data format and colour depth.
“Square pixel” or “pixel ratio” means that the work on the computer is based on square pixels. However the pixel ratio for work carried out on video or film is different. The PAL 4:3 format has pixels that are wider than they are high. They are even wider with 16:9.
