Video resolution
Select the resolution by entering values for the
Width and Height. You can also
select
Use input resolution to stream or record at your input source’s original
resolution. Monarch HD does not support upscaling the input source.
¦NoteIn Stream-and-record operating mode, if the current record encoding
resolution exceeds a width of 1280 and/or height of 720, and you want to stream
at a resolution greater than 1280×720, the stream and record settings must use
the same encoding settings. In this case, you must select the
Use stream
settings for recording
option.
Frame rate
You can choose to stream or record at your input source’s
Full frame rate, or at a
Half or a Quarter of your source’s frame rate.
The Monarch HD does not support upscaling the resolution or frame rate of the
input source. If
Full is selected from the Frame rate list, the frame rate will
automatically be set to
Half of the input source’s frame rate after clicking Apply.
Target video data rate
Enter the target
average video data rate for your session. When entering an
average data rate, the
minimum and maximum data rates are automatically set
to 90% and 110% of the average data rate, respectively. The default minimum
and maximum values are suitable in most instances, however, you can change the
minimum and maximum values to suit your needs. The maximum average video
data rate for streaming or recording depends on the selected operating mode (see
“Monarch HD operating modes” on page 30). Monarch HD uses a variable data
rate when encoding.
GOP size (streaming)
Enter the
GOP size (distance between I frames) to which you want to encode
your input source for streaming. Monarch HD uses the IP pattern when encoding
for streaming. For example, a GOP size of 10 creates a GOP structure of
IPPPPPPPPPI.
GOP structure (recording)
Enter the GOP size (distance between I frames) and distance between P frames to
which you want to encode your input source for recording. Monarch HD uses the
IBP pattern when encoding for recording. For example, a GOP size of 15 and a
distance between P frames of 3 creates a GOP structure of
IBBPBBPBBPBBPBBI
Include audio
Select
Include audio to stream or record the selected audio source along with
the video. Monarch HD uses the AAC audio format. Clear this option if you do
not want to include audio in your stream or recording. For more information on
