Audio Codec
AAC-LC ADTS
AAC-LC LATM
PCM
AC-3 Passthru
MPEG-1 Layer 2
None
The codec to use for audio. Available
options depend on what was licensed.
Audio Bit Rate
32 – 384Kbps (
128Kbps
)
The bit rate to use for audio.
Video Resolution
WQVGA – 1080i
Follow input
The input resolution [
Note 1
]. “Follow
input” means use the capture resolution to
determine the encode input resolution.
Rate Control
CBR
VBR
Choose between “constant bit rate” and
“variable bit rate”. “Constant bit rate”
will cause the encoder to drop frames if it
detects the bit rate being exceeded.
Video Bit Rate
0 -12000k (
8000k
)
The bit rate to use for video.
Video Profile
Baseline
Main
High
The H264 profile of the bitstream.
Generally High is used for > D1, Main for
D1, and Baseline for < D1.
Gop Size
15, 30,
60
, 120, 240
I-frame frequency. A GOP size of 60, for
example, would mean 1 I-frame every 60
frames.
Video Burst Size
150 – 2000ms (
300
)
# of ms to buffer. The higher the value,
the smoother the encode, but also the
higher the latency.
Video Codec
H.264
, MPEG-2
The codec to use for video encoding.
Frame Decimation
None
, 1/2, 1/3, 1/4
Used to reduce the frame rate. For
example, selecting “1/2” frame decimation
for 30fps input would cause a bitstream to
be encoded at 15fps.
D1 Sharpness
(For Composite Input
Only)
0
-2
Controls the peak and coring filters of the
analog front end for D1. 0 is a normal (flat)
setting. 2 causes the highest sharpness
gain. The encoder will encode more
efficiently with less sharp pictures. If the
bit rate is high, this can be used to enhance
the picture quality. The general
recommendation is to leave this at 0.
Output Interface
Ethernet (VBR)
ASI
ASI+Ethernet (CBR)
Selects where bitstream is output
(Ethernet, ASI, or both). Note: RTP can
only be streamed over “Ethernet (VBR).”
For UDP streaming, specifying “CBR” will
cause insertion of null packets where
necessary.
