o

Horizontal Resolution:

Enter the desired horizontal resolution in pixels.

o

Vertical Resolution:

Enter the desired vertical resolution in pixels.

Notes:

o

The 9992-ENC will not upscale a signal. If you enter a resolution that is higher
than the corresponding resolution of the incoming signal, that incoming resolution
will be used. For example, if you select scaling to 900×900 and the incoming
signal is 1280×720, the encoder output will be 900×720.

o

If the input signal is interlaced and the vertical resolution is not a multiple of 16,
the encoder output will be converted to progressive.

o

The encoding standards supported by the 9992-ENC produce signals whose
horizontal and vertical resolutions are multiples of 16. If you select a resolution
that is not a multiple of 16, it will be internally rounded up and the signal will
include cropping information for the decoder.

Progressive Half Frame Rate:

If this box is checked, progressive signals at 50, 59.94

and 60 frames/sec will be converted respectively to 25, 29.97, and 30 frames/sec. This
box has no effect for other types of signals.

Progressive Conversion:

Check this box to convert an interlaced signal to progressive.

This control has no effect for a progressive signal. The signal frame rates are not
changed.

Spatial Filter Strength:

Select the strength of the spatial filter. A setting of 0 (zero)

disables the filter. Increasing the spatial filter will make the image softer, which may
provide better overall quality for lower bit rates.

Noise Reduction:

Select the level of noise reduction. The noise reduction filter is only

available for interlaced content and has no effect for progressive content.

Video Rate Mode:

Select CBR (Constant Bit Rate) or VBR (Variable Bit Rate).

o

CBR

: Enter the desired elementary stream bit rate in bits/second.

o

VBR:

In VBR mode, multiple parameters are configurable:
