Notes
Video Source
HD-SDI (CH1)
Composite (CH2/3)
HDMI (CH2/3)
The input source. HD-SDI is the only option for
CH1. Composite and HDMI are supported by using
the CH2 or CH3 tabs (See page 38 for details on
creating additional channels).
16:9
Checked
Unchecked
This can be used for any SD input (NTSC or PAL
coming in through composite or 480i / 480p / 576i
/ 576p coming in through SDI or HDMI). When this
is checked, the aspect ratio in the bitstream is set
to 16:9. For any HD input this value is ignored.
Video Resolution
176x144 – 1920x1080
(
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 Bitrate
100 – 12000K (
6000K
)
The bitrate.
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
Full
Half
Quarter
Sixth
Used to encode at less than the input frame rate
(for example, an input frame rate of 30fps with
Frame Rate set to “Half” would cause an output
stream of 15fps). If interlaced input is used then
this is used to reduce the number of fields being
encoded.
[Note 2]
Number of B-frames
0
– 2 (
0
)
The number of B-frames. A value of “0” means B-
frames are disabled.
