Inter Frame Motion Detection (IFMD)
For deinterlacing video sources (not applicable for film) the IFDM control trades-off between minimizing combing
artifacts (small values) verses maximizing detail (larger values) using the IFMD setting. The default setting is 6.
This control is most effective with “Video” deinterlacing mode. The command is:

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:

Genlock
Genlock is used to minimize 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:

Game Mode
To minimize video processing latency, when playing video games, turn “Game Mode” on.
Interlaced sources
480i/576i/1080i are treated as 240p/288p/540p. PiP/PoP, 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.

Reinterlace
Adds reinterlacing for 480p and 576p sources. This can provide dramatic improvements to a picture that has been
poorly deinterlaced prior to coming into the Radiance. Reinterlacing also allows for taking in 480p/576p movies and
going out at 24/48/72Hz. With this command you can "allow" or "disallow" quick remote key control for a
particular resolution as well as turn it on/off. If "Reinterlace <> Keys" are set to ‘allow’ the left/right arrow buttons
on the remote can then be used to control reinterlacing. The left arrow toggles reinterlacing on/off and the right
arrow toggles the field order. Depending on how the picture was deinterlaced, the field order may or may not be
important but it can be quickly toggled to see if there is any difference.

Input Enhancement Controls
Sharpness
This command is used to adjust the sharpness for all inputs. There are controls for horizontal, vertical and diagonal
sharpness (edges) and texture (fine detail). It is generally best to leave these controls at the default setting of 0
or to use moderate settings. Using higher settings can introduce image artifacts. Some people prefer having all 6
settings set the same. Other people prefer only using the diagonal parameters. The command is:

Noise Reduction
Mosquito noise and block artifact noise are both seen in compressed material. The Radiance has both temporal
and special noise reduction to help reduce the noise level these artifacts introduce into the image. Block artifact
reduction is also supported and can be useful with overly compressed video. The command is:

Adaptive Contrast
Adaptive Contrast varies the contrast based on the average level of the central 60% of the picture. When you
adjust the contrast the effect is shown in a centered window for evaluation. The command format is:
