Video Template Settings
The lower area of the Video page has a set of parameters that can be controlled by pre-
configured templates. Use the Load Template button to populate the Video Template Settings
with pre-configured video values (or select
None). The video settings vary depending on the
selected
Video Format and Video Aspect Ratio. Choose a template based on motion and
bandwidth. 750k High Motion is the default template. All video encoder parameters defaults will
match these values.
Table 4. Video Template Settings †
Contrast Boost
Enhancer
Default = Disabled. Supplements existing Contrast setting. Check to
enable.
Edge Enhancer Default = Disabled. Sharpens edges in active video region for both
Luma and Chroma. Set to Low, Med, or High.
Horizontal
Frequency Boost
Default = Disabled. Amplifies the appropriate video frequency band.
• Med – amplifies the middle frequency band of the displayed video.
• High – amplifies the highest frequencies of the displayed video.
• Med & High – amplifies the highest and middle frequencies of the
displayed video.
Brightness 0–100. Default = 50. Brightness is information about the varying light
intensity of an image which is best described as brightness.
Contrast 0–100. Default = 50. The contrast is the range of light-to-dark values
of an image that are proportional to the voltage differences between
the black and white levels of the signal.
Saturation 0–127. Default = 64. Saturation is the spectral intensity of a color. It
operates on the PbPr chroma components of the color space by
increasing or decreasing both components by the same percentage.
Tint -50–50 degrees. Default = 0. The tint is the attribute by which a color
may be identified within the visible spectrum. Tint refers to the
spectral colors of red, orange, yellow, green blue and violet. Note:
Adding Tint reduces the saturation.
Blackout Bottom
(Top, Left, Right)
0–10. Default = 0. Some files include additional information that
results in undesirable artifacts on some sides of the video frame. This
option blacks out an area around the player window—not a specific
number of lines. (Top, Left, and Right are only available with HD
inputs.) Be sure to test your results when using this option.
