- Default
:
default strategy.
The input AFD value will not
be analyzed. Choose the conversion to be applied in case of
narrower (
Default conversion to narrover aspect
ratio
) and wider (
Default conversion to wider aspect
ratio
) aspect ratio (Refer to
Appendix ’Aspect Ratio
Conversions’
,
Section ’Conversions according to default
strategies and output display aspect ratio’
).
- AFD automatic
:
automatic AFD strategy.
The input
AFD value determines the conversion (Refer to
Appendix ’Aspect Ratio Conversions’
,
Section
’Conversions according to input AFD and output display
aspect ratio’
).
If no AFD value is set in the input video, the default
conversion is applied.
- AFD manual
:
manual AFD strategy.
The configured
AFD value determines the conversion (Refer to
Appendix ’Aspect Ratio Conversions’
,
Section
’Conversions according to input AFD and output display
aspect ratio’
).
Output frame structure
: choose if the video structure should
be
Progressive
or
Interlaced
.
Modify frame rate
: if set to
False
, the input frame rate is kept
in output. If set to
True
,
-
define the
Frame rate
in frames per second.
For instance, if you want to change a 1080@30 fps input into
a 720p@60 fps output, you need to duplicate the output
frame rate; using this parameter will give you the best
video quality for this case.
-
define the
Web TV: adaptation to external packager
.
Set it to
true
if all the following conditions are met:
•
A channel contains adaptive bitrate streams with
different frame rates.
•
An external packager is used. The internal design of the
external packager requires that the IDR frame of all the
chunks of a given period has the same PTS. In this case,
an adaptation may be necessary.
If the external packager does not have this limitation, do not
use this parameter as it may reduce the video quality.
This parameter is ignored when there is no chunker before
the frame rate adaptation.
- 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
.
