Autofill
When Video AutoFill is turned
ON, the encoder will calculate
and use the max video bit rate
for the current TransMuxRate
setting. This is recommended. If
Autofill is set to OFF the encoder
will use the manual setting for
the video bitrate.

Latency
It is dependent upon the video
rate, frame size/rate
(NTSC,PAL,HIGH-DEF) and GOP
structure. Long IBBP GOPs will
produce higher latency over
short IP GOPs. Short IP GOPs at
lower bit rates produce lower
quality video.
LONG: Latency will measure close
to 1 second.
NORMAL: Should be used for
distribution and standard
contribution transmissions. Latency
is approximately 3/4 second.
LOW: Latency is approximately 3
frames less than NORMAL.
VERYLOW: Latency is approximately
5 frames less than NORMAL.
3FRAME/2FRAME/1FRAME
Feature keyed option that provides
super low end-to-end latency when
paired with an RD-71/RD-70. GOP
settings are ignored.
Interoperability with other vendor
decoders is not guaranteed in these
modes.
4.11
Latency Trim
Use this setting in conjunction
with the Latency setting to fine
tune the latency in order to
match various manufacturers
latency settings. The setting is
rounded down and applied in
video frame multiples (a +50
mSec offset would result in the
following.. one additional frame
delay with 29.97 frame material
and two additional frame delays
with 59.94 frame material).
Max range is -400 to +200 and is
constrained based on the
ENCODELATENCY setting (NORMAL)
and current video mode.
