Configuration
• Anamorphic – this mode is designed to be used with material originally
captured with an anamorphic lens. It ensures that the top and bottom
edges of the input aspect ratio match the top and bottom edges of the
output aspect ratio. When used with standard 4:3 material, it will have
the effect of stretching the material horizontally as illustrated in
Figure 12 . This results in a distortion of the geometry of the image, par-
ticularly causing circles to appear as ovals when present in the image if
the input image was not recorded with an anamorphic lens.

• 14 x 9 SP – this mode minimizes the left and right cropping of the image
and stretches it leaving the result for both down and up conversion as
shown in
Figure 13 . The image can be aligned with the aspect ratio con-
trols and the matte color of the background can be changed.
