-\CGG{} allows you to vary the input and output aspect ratio in the ways indicated in the previous section: by varying the pixels of the sides (Width/Height) or by setting a multiplication coefficient (W/H Ratio; in this example: placing $H Ratio = 816 : 1080 = 0.7556$) which performs the calculation automatically. If you set \textit{W Ratio} and \textit{H Ratio} at the same time with the same values, they work as multipliers and you get a resizing of the canvas, without altering the initial aspect ratio. If you change them to two different values or change only one of the two parameters, leaving the other at 1, you get an anamorphic video, with the pixels no longer being square (1:1) but becoming rectangular, deforming the image. To avoid anamorphosis, the \texttt{Display Aspect ratio} must also be adjusted at the same time, for example, with the Auto option. \textit{Anamorphic} format is a complex field that is discussed in the Raffaella Traniello's guide: {\small \url{http://www.g-raffa.eu/Cinelerra/HOWTO/anamorphic.html}}.

If you use a non-standard aspect ratio, this has impact on other areas like titles, included stills and included non-anamorphic footage. To avoid anamorphosis, the \texttt{Display Aspect ratio} must also be adjusted at the same time, for example, with the Auto option. \textit{Anamorphic} format is a complex field that is discussed
