Input Color Space

Enter the color space of the source here – HDTV YCbCr, SDTV YCbCr, Auto YCbCr (switches color space according to whether input is HD or SD), Studio RGB, or Extended RGB. If you do not know the color space of the source, use the setting that produces the best picture, especially with dark scenes.

Brightness / Contrast / Color / Tint

If a source needs Brightness (black level), Contrast (white level), Color (saturation), or Tint (hue or phase) adjustment, you can do it here. The factory default for each of these is 50. If input is RGB and output is RGB, Color and Tint are not adjustable, so that color space conversion is avoided. If you need to adjust the image when output is set to RGB (or Extended) in menu 8, set the source to YCbCr output.

Film Mode

Did the source originate from film or from video? If from a video camera, which type? If it’s a film source on TV, was a regular pattern of fields deleted to change the playing speed? Is it animation, and if so, according to which animation spec? Is it a mix of sources edited together? Are video characters being scrolled across a film source?

In order for a video processor to provide best image quality, it must detect the source’s cadence, or pattern of field sequence, and deconstruct it accordingly. The Gennum VXP processor can not only do that, it can do so even when the input is high-definition. Film Mode can be overridden by changing the setting from ‘Auto’ to ‘Off’, but don’t do it unless you need to.

Detail Enhancement

Digital processing is used to do what the name implies – experiment with the level adjustment and leave it where the picture looks best. The factory default is 0.

Noise Reduction

This can be used to reduce or remove ‘snow’ in the picture, often seen in broadcasts – experiment with the level adjustment and leave it where the picture looks best. The factory default is 0.

Motion Threshold

A high-quality deinterlacer has to treat the areas of the picture that contain motion differently from the areas that have very little or no motion. The motion threshold is the point where one type of deinterlacing changes to another. The factory default (4) should work best but adjustment is provided in case it’s needed.
