picture 2     (768x576 pixel)

Through the settings of this window it is possible to turn an image taken in an unknown format, into an image with PAL video standard format (768x576) or in any other format. If a video image is acquired with a compression of 720x576 (pic.1) and you open it in a PC in PAL video format, the image undergoes such a transformation to make a circle an oval (pic.1) and a square a rectangle.
Inserting the right compression ratio (the program executes it in automatic clicking on Take the ratio from the X-Y axis) the image is proposed again with the real proportions (pic.2)
