Partitioning
Disabled
(H.264 only) Check this checkbox to enable
Intra-Picture Sub-Partitioning.
Intra-Partitioning is a setting that allows the
use of a smaller macroblock partition during
the video macroblock encoding process.
NOTE:
Intra-Partitioning requires that the
H.264 decoder be High Profile compliant.
Intra-Partitioning provides better visual
quality because it gives the video encoder
better coding tools.
TIP:
Noisy Matrix completion is enabled
automatically when Partitioning is enabled
and video bitrate is under 800 Kbps. Noisy
Matrix completion enhances video image
“noise” reduction to improve video quality at
lower bitrates and make blocky artifacts less
visible.
Intra Refresh
Disabled
(H.264 only) Check this checkbox to enable
Intra-refresh video encoding support.
Intra-refresh is a video encoding mode of
operation in which no distinct IDR frame is
sent in the video elementary stream. Instead,
the macro-blocks that make up the IDR
frame are sent gradually within a certain time
so that the entire video reference frame is re-
built (at the decoder) within the number of
frames specified by the
parameter. Intra-refresh minimizes latency,
smooths the video bitrate, and minimizes
GOP pulsing artifacts.
TIP:
Intra-refresh requires that the decoder
and streams be started first.
Intra Refresh
Rate
60
(H.264 only) Specifies the number of frames
over which the entire picture is refreshed.
1..5000
NOTE:
If the refresh rate is set too low, a left-
to-right wave-like artifact may result.
Partial Image
Skip
Disabled
Allows the encoder to skip part of the image
in order to respect the bitrate limit.
