Encoding
MPEG-2 Encoder
Description
The
MPEG-2 Video Encoder
processing component lets you encode
video in MPEG-2 format, 4:2:0, 8 bits, from SD to HD.
Figure 3-285. MPEG-2 encoder parameters
Parameters
For this processing component, you must set the following parameters:
Rate mode
: indicate if the component bitrate should be
CBR
,
Capped
VBR
or
Statmux
. If set to
Capped VBR
, indicate the characteristics of
the video component, as shown hereafter.
Min bitrate
: indicate the minimum ES bitrate that the video
component should have.
Max bitrate
: indicate the maximum ES bitrate that the video
component should have.
Rate Control Quality
: set the picture quality level required, in
percentage. The value must be between 10 and 90% (best
quality). Default value: 70%.
It is not possible to use values outside of the bitrate range, and
it is not recommended to reduce the bitrate range.
Bitrate
(only for CBR): enter the bit rate value (without encapsulation
overhead), in bits per second.
If you set the minimum bitrate to a lower value than the minimum
value of the range, the value applied is the minimum value on the
range, and inversely for the maximum bitrate.
