If you prefer a center cut output rather that letter box, select the CCUT/ZOOM as your aspect ratio selection:
16:9 Ratio Image 4:3 Ratio Display
SD to SD conversions
A special note must be made concerning the operational modes used for SD to SD conversions. While
most SD programming may utilize a 4:3 aspect ratio, some SD source material may exist in 16:9. For
such projects, you have to tell the Teranex Processor that the SD source is 16:9.
First, press the IN button on the front panel. If you are currently feeding your source to the Processor,
the SD input format will be automatically detected as either NTSC or PAL. Next, in the ASPECT control
section, press the LBOX/PBOX button to define the input as 16:9. This step is required if you are
processing an SD 16:9 widescreen source.
If the SD video input is 4:3, press the CCUT/ZOOM button.
ANAM - Anamorphic
Anamorphic mode ensures that the entire output screen is filled by either stretching or squeezing the input
image. This mode is designed for use with material that was originally captured with an anamorphic lens,
thereby generating an output image with correct geometry when stretched horizontally to 16:9. When used
with standard 4:3 source material, it will have the effect of stretching the material horizontally to 16:9, causing
circles to appear as ovals, etc.
