- Coder delay
: this parameter can have 3 values:
-
Standard
: the coder delay is 53 frames. It gives the highest
video quality.
-
Short
: the coder delay is 39 frames.
-
Ultra-short
: the coder delay is 25 frames. There is an
impact on video quality.
Deblocking
: enter a value to define the strength of the deblocking
filter that will be applied to the stream. This helps to prevent the
blocking artifacts resulting from image compression. Disabling the
deblocking gives a sharper image, which might be a good choice
when the video bitrate is high.
Closed caption
: set to Insert closed caption if you want closed
captions that are present in the incoming MPEG-2/H264 video stream
or from the SDI input to be collected and integrated in output.
Psycho-visual enhancement
: leave to
ON
to obtain the best video
quality. Set to
OFF
to obtain better results with basic PSNR/DMOS
video quality analyzers (however the video quality is lower).
Web TV chunk size accuracy enhancement
: Check this option
if you connect the encoder to a packetizer for Web TV output and if the
accuracy of the chunk size is a major concern. It will not be possible to
configure the Decoder Delay, it will be fixed to 500ms. Only Coder
Delay is configurable.
