Notes
Video Source
HD-SDI
HDMI2
Composite2
The input source. “HD-SDI” appears for CH1.
“HDMI2” and “Composite2” appear for CH2.
Video Resolution
320x180 –
1920x1080
Follow Input
The encode resolution. If this resolution is
different from the capture resolution,
resizing will occur. “Follow Input” generates
the resolution based on the capture
resolution. [
Note 1
]
Video Bit Rate
100 – 12000K (
6000K
)
The bit rate.
Video Profile
High
Main
Baseline
The H264 profile of the bitstream. Generally
High is used for 1080p, Main for D1, and
Baseline for < D1.
Frame Rate Divider
1
, 2, 4
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 number of B-frames. A value of “0”
means B-frames are disabled.
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 – 3000 (
2000
)
# of ms to buffer. The higher the value, the
smoother the encode, but also the higher the
latency.
Audio Enable
True
, False
True -> Encode audio.
