Frame rate
: the output frame rate shall be configured (this
preprocessing should not be used with interlaced video).

Web TV:
adaptation to external packager
: (this
parameter is ignored when there is no chunker before the frame
rate adaptation): when a channel contains adaptive bitrate
streams with different frame-rates and an external packager is
used, an adaptation may be necessary if the internal design of
the external packager requires that the Idr frame of all the
chunks of a given period has the same PTS. If the external
packager does not have this limitation, do not check this
parameter as it may reduce the video quality.
Ensure accurate frame rate according to device
internal clock
: set to
true
when your output stream must be
sharply synchronized with the device internal clock.
Do not set this parameter to true if your workflow also uses the
TS Video/Audio Extractor and the
Clock Management
parameter is set to
Keep input clock
.
Clipping
: clip a video.
