For a 2.35 display, when 16:9 NLS is enabled, the image will fill the screen with a 16:9 or 1.85 source for any
output aspect ratio up to 2.40. If the output aspect ratio is greater than 2.40, software limits the maximum width
to the equivalent of 2.40 and adds left and right sidebars.
Select the parameter to adjust using the  and  arrows, and change the value of the selected parameter using
the  and  arrows. The command is:
MENU → Input → Video Setup → [Resolution] → Size → [Aspect] → NLStretch → OK
Input Masking
The masking command allows you to cover up the sides of the video source. It is different then cropping in that
the video is not stretched to fill the screen. It can be used for pass-through modes, where you do not want the
Radiance to scale the picture, to cover up some video noise on top/bottom/side of the picture. Another situation is
to cover up and change the gray level of the black bars added by a video source, surrounding a letterboxed image.
When you select the command you must first select which mask number you wish to use. There are 15 available
masks that can be shared among different input memories. After selecting the mask number, you can adjust how
much the mask covers the 4 sides of the input. The last step is to alter the gray level for the 4 sides. If an input
mask is on, its gray level takes precedence over the gray level of the aspect bar. The aspect bar gray level can be
adjusted under Output→Configs→[Config]→Other→Graybar. Also, if aspect bars are requested (via differing
input and output aspects) the masking is added to the aspect bar width. The command is:
MENU → Input → Video Setup → [Resolution] → Size → [Aspect ratio] → Masking → OK
Input Control Menu
Deinterlacing Mode
The default deinterlacing mode is “Auto.” This mode automatically switches between video and film deinterlacing
and is best for mixed-mode sources that can change between video and film. For sources that are known to be
interlaced-video, choosing “Video” deinterlacing mode can improve image quality. For sources that are known to
be film sources, choosing 'Film' deinterlacing mode can improve image quality. For 60Hz interlaced film sources the
output rate must be 24, 48, 60, or 72 Hertz. For 50Hz interlaced sources the output rate must be 50 Hertz. For
“Film” mode, Sharpness, Noise Reduction and Adaptive Contrast settings are not available. The command is:
MENU → Input → Video Setup → [Resolution] → Control → Deint → Mode→ (Auto,Video,Film)
Inter Frame Motion Detection (IFMD)
Controls the trade-off between minimizing combing artifacts (small values) verses maximizing detail (larger values)
when deinterlacing video sources (not applicable for film). The default setting is 6. This control is most effective
with “Video” deinterlacing mode. The command is:
MENU → Input → Video Setup → [Resolution] → Control → Deint → IFMD→ (0-15)
Deinterlacing Field Flip
Some source devices do not follow conventions for the order of video fields. This can be seen as excessive
combing in the video. While generally not required, this command allows the input fields to be swapped so these
out-of-spec sources can be properly deinterlaced. The command is:
MENU → Input → Video Setup → [Resolution] → Control → Deint → Field → (On, Off)
Genlock
Minimizes video delay, for 480i/1080i to 24Hz conversion, and to avoid an occasional dropped or repeated frame.
It can slow down source and mode changes, so Lumagen recommends setting Genlock to ‘off’ for cable and
satellite set top boxes. The command is:
MENU → Input → Video Setup → [Resolution] → Control → Genlock → (Auto, Disabled)
Game Mode
Minimizes video processing latency, when playing video games. Interlaced sources 480i/576i/1080i are treated as
240p/288p/540p. Deinterlacing, and Enhance settings are not available. Typically game mode is enabled for a
specific input memory that is then selected while playing games. For games that have a vertical rate that matches
the Radiance output vertical rate, turning “Genlock” on can further minimize video latency. Game mode is not
intended for video/film program material, such as television shows. The command is:
MENU → Input → Video Setup → [Resolution] → Control → Game Mode → (On, Off)
