channel on an HD output:

) to expand the configuration tree.
2. Choose a video track in the configuration tree, such as
Track 1
.
3. Click the
Up Conversion
button to see the aspect ratio choices.
4. Select the desired aspect ratio conversion from the available options
- Pillarbox - The 4:3 aspect ratio is maintained, centered on the screen, with black
bars filling the left and right portions of the 16:9 display.
- Half Pillarbox - The picture aspect ratio is maintained, but the image is slightly
enlarged. The top and bottom of the image are slightly cropped, and thin black
bars fill the left and right portions of the 16:9 display.
- Zoom - The picture aspect ratio is maintained, but the image is enlarged so that
it horizontally fills the HD display. The top and bottom of the 4:3 SD image are
cropped to fit in the 16:9 display.
- Stretch to Fit - The picture aspect ratio is distorted. The image fills the screen
vertically without cropping, and is stretched horizontally to fill the 16:9 display.
This conversion up-converts Full Height Anamorphic (FHA) 16:9SD material.
