Notes
Video Source
HD-SDI1,
Composite
Where to get input for channel 1.
Video Resolution
320x180 –
1920x1080
Follow Input
The input resolution for channel 1 [
Note 1
].
Video Bitrate
100 – 12000K (
6000K
)
The bit rate for channel 1.
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
1
– 3 (
1
)
This should actually be thought of as the #
of frames after a P-frame that the next P-
frame occurs. A value of “1” means 0 B-
frames occur. A value of “2” means 1 B-
frame, and so 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 and higher the
latency. See page 19, “Tuning for Latency”
Audio Enable
True
, False
True -> Encode audio.
Audio Info (Entries for each of the 4 subchannels within the HD-SDI source)
Enable
yes (for Sub Channel 1)
, no
Used to select which subchannel should be
used for the audio source. Only one
subchannel can be enabled.
Codec
ARM AACLC
ARM AACHE
DSP AACLC
ARM AACHE V2
The codec to use for audio. Note that “DSP
AACLC” and “ARM AACHE V2” are not
supported in this release.
Sample Rate
48KHz
The sample rate of the audio.
Bit Rate
12Kbps – 320Kbps (
128Kbps
)
The bit rate of the audio.
Mode
Mono
Stereo
Select between stereo and mono inputs.
Source
HD-SDI1
HD-SDI2
Analog
None
Where to get audio for that subchannel.
