entropycoding
CAVLC
Select the compression scheme:
•
CAVLC:
Context-adaptive Variable-length
Coding is a lower-complexity alternative to
CABAC. CAVLC produces lower quality,
but is easier to decode.
•
CABAC:
Context-adaptive Binary
Arithmetic Coding is an algorithm to
losslessly compress syntax elements in the
video stream. CABAC compresses data
more efficiently than CAVLC and should
produce better quality, but requires
considerably more processing to decode.
NOTE:
The H.264 decoder must be Main
Profile compliant or higher to decode a
CABAC video stream.
TIP:
Generally, you get better visual quality if
you are using CABAC because it is more
efficient.
partitioning
Off
Enables or disables Intra-Picture Sub-
Partitioning.
On,Off
Intra-Partitioning is a setting that allows the
use of a sub-macroblock partition called the
“Intra8x8 block” with all the intra-prediction
modes associated with it.
NOTE:
Intra-Partitioning requires that the
H.264 decoder be High Profile compliant.
Generally, you get better visual quality if you
enable Intra-Partitioning 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.
