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. The video settings vary depending on the selected
Video
Format
and
Video Aspect Ratio
. Choose a template based on motion and bandwidth. All video
templates use the Baseline Profile.
750k High Motion is the default template. All video encoder
parameters defaults will match these values.
Table 4. Video Template Settings
Video Aspect Ratio Video Aspect Ratio is the ratio of the width of the image to the height
of the image. Standard TV images generally use an aspect ratio of 4:3.
Set this value to match the video input source, either 4:3 or 16:9.
Luminance 0–255. Default = 128. The luminance is the information about the
varying light intensity of an image, which is best described as
brightness.
Contrast 0–127. Default = 64. 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. The saturation is the spectral purity or intensity
of a color.
Hue -128–127. Default = 0. The hue is the attribute by which a color may
be identified within the visible spectrum. Hue refers to the spectral
colors of red, orange, yellow, green blue and violet. Note: Adding hue
reduces the saturation.
Bottom Blackout
Area 0–10. Default = 0. Some files include additional information that
results in undesirable artifacts at the bottom of the video frame. This
option blacks out an area at the bottom of the player window—not a
certain number of lines. Be sure to test your results when using this
option.
