pix ratio

Purpose
To set and display the pixel ratio for the output medium.

Usage

Comments
Certain video formats (d1, hdtv) do not use square pixels. Therefore the image must be rendered with a specific pixel ratio. For example pal Video image ratios are always set in a 4 x 3 format. When using square pixels this 4 x 3 image ratio will be achieved with 768 x 576 pixels. In d1 format the pixels are not square but stretched in the x-direction (1.067). In this case the 4 x 3 image ratio requires 720 x 576 pixels. GIG will automatically set the modeling windows to the same ratio as the selected output medium settings.
