Examples of Auto aspect ratio correction for 4:3 SD signals
6.6 Aspect ratio size and position controls
Depending on the input format and selected output format there are up to seven fixed aspect
ratios available. Each of these seven aspect ratios can be adjusted independently for picture
size and position; the picture may also be cropped on all four edges. Once the controls are
set they are automatically recalled whenever the particular aspect ratio is active.
6.7 HD to HD Aspect Ratio Correction
HD sources are normally always 16:9 but may not have been created in that aspect ratio and
HD to HD aspect ratio correction allows for some adjustment of previous corrections. There
are some limitations with HD to HD aspect ratio correction that the user should be aware of,
namely:
The conversions are only available on the UP-DOWN-ATX-VF and UP-DOWN-ATXS-VF
and are functional when all output formats are the same as the input format.
The conversions are fixed, with the size, position and crop sliders having no effect.
“4x3 to 14x9 Pillarbox” (4:3 to 16:9 in a 14:9 Pillarbox) is under-sized by about 4%.
“4x3 to 14x9 Pillarbox” is only possible for the 720p50, 720p59.94 and 1080i50 formats.
For other formats, a 4x3 Pillarbox is used.
“16x9 to 16x9 Letterbox” (16:9 stretch to 16:9 Letterbox) is only possible for the 720p50,
720p59.94 and 1080i50 and 1080p50 formats. For other formats a 14x9 Letterbox is
used.
