8.5.2 Pre-Processing Parameters
Pre-processing is a collective term covering all processing of the video signal done prior to the
encoding process. The purpose of pre-processing is twofold.
• Make the video signal easier to encode.
• Analyze the video and give advance information to the encoding process
Figure 8.30 -
Universal Transcoder- dense broadcast preprocessing parameters
The following parameters are available for configuration:
Frame rate
Specify output frame/field rate from drop down list. (Frame rate
for progressive output and field rate for interlaced output)
• 50Hz
• 59.94Hz
• 60Hz
Rescale
Configure the format the video shall be transcoded to.
• HD Module: 1080i, 720p.
• SD Module: 576i,
Horizontal Rescale
The horizontal resolution (pixels per line) is defined by the
selected video format, but can be reduced. The options depend
on the selected video format on the Source Tab. Reducing
horizontal resolution will make it possible to use lower bitrates
when encoding since information is removed before encoding.
