Notes
Video Info
Video Source
HD-SDI1
Where to get input for channel 1. Always HD-
SDI1 for this version.
Video Resolution
320x180 –
1920x1080
[
Note 1
]
Follow Input
The encoder resolution for channel 1.
If the Z3-MVE-40 is in “Encoder No Resize”
mode, this must either be “Follow Input” or
the resolution of the source video. Any
other value will result in unpredictable
behavior.
If the Z3-MVE-40 is in “Encoder Resize”
mode, a resolution other than “Follow Input”
or that of the source resolution will cause a
resize to the specified resolution. Note that
performance limits apply in this mode (the
Z3-MVE-40 supports resizing of 4x 1080i
channels up to 4x 1280x720).
Using “Follow Input” will cause the encode
resolution to be whatever the detected
resolution of the source is.
Video Bitrate
100 – 16000K (
6000K
)
The bitrate for channel 1.
Video Profile
High
Main
Baseline
The H.264 profile of the bitstream. Generally
High is used for 1080p, Main for D1, and
Baseline for < D1.
Frame Rate Divider
1
, 2, 4, 6
Used to encode at less than the input frame
rate (for example, an input frame rate of
30fps with a divider of 2 would cause an
output stream of 15fps).
Number of B-frames
0
– 2 (
0
)
The # of B-frames the channel should use.
Noise Filter
On
Off
Turns on an optional noise filter. This helps
reduce noise in high-detail areas (for
example, around text). The tradeoff is some
detail may be lost when the filter is turned
on.
GOP Size
10 – 240 frames (
60
)
I-frame frequency [
Note 2
].
Maximum Delay
0 – 9999 (
2000
)
# of ms to buffer. The higher the value, the
smoother the encode, but also the higher the
latency. See Section 6.16, “Tuning for
Latency” on page 26 for more details.
