Color Format Type
Sets the outputs color format. It should be set to
“
Auto
”
except to correct for a color format error in the display.
Normally Bt.709 is used for SD/ED, HD, and UHD (non-HDR) material. For SDR sources the Pro automatically
converts the data from Rec 601 to Rec 709. So you would not normally use a Rec 601 output format. The

Dither
Some displays show contouring on images that have gradients because the physical pixel depth of each pixel, or
processing precision, is limited. The dither control can be used to enhance the resolution of the display and reduce
contouring. Dither position sets the bit size of the pixel for dithering. Orientation controls the frame-to-frame
randomization. It can be set to fixed or dynamic. Masking can be turned on to clear the lowest bits after the dither
addition. The command is:

Mask
Allows you to “blank” the edges of the video image on the output without changing its position or scaling. This is
useful to blank bad pixel data from the source that shows on screen, when you want to keep the “pixel perfect”
setup (i.e. no scaling). You can also use the Mask function to adjust overscan to match the projection screen. The

Shrink
Adjust the image size to fit inside a screen masking system. This command is used when outputting to a 2.35
screen when no Anamorphic lens is used. The command is:

Vertical Keystone
Adjust for a projector vertical placement offset.
Note:
Use this control *only* if the projector does not have enough optical keystone adjustment since it
will reduce the resolution of the image since it “down scales” to correct the Keystone.

black to white in sixteen steps. The command is:

Screen Aspect Ratio
Select the screen aspect ratio. The screen aspect ratio range is 1.10 to 2.50 and is entered in units of hundredths
(e.g. 16:9 is entered as
178
). If you have a normal fixed aspect display, select the “Single output aspect” which is
the default setting. If you have a movable anamorphic lens or a projector with programmable lens-shift and focus
that you are using
, select “Output aspect per input aspect.”
For the “Output aspect per input aspect” mode, there is a special case when you use NLS. When the input aspect
is 4.3+NLS the output aspect assigned to the 16:9 entry is used. When the input aspect is LBOX+NLS, 16:9+NLS,
or 1.85+NLS the output aspect assigned to the 2.35 entry is used.
The command is:
