Matrox Monarch HDX - Video Resolution and Frame Rate Settings; Target Bit Rate Configuration

Encoder Settings
Video resolution
You can select the stream/record resolution you want 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. The Monarch HDX does not support
upscaling the resolution or frame rate of the input source (for streaming or
recording).
Frame rate
The Frame rate drop-down menu lists the available resolution options, based on
your source's frame rate. You can choose to stream or record at your input
source's full (actual) frame rate, or at a half of your source's frame rate.
A profile's frame rate may be overridden, if the profile's frame rate is
incompatible with the source's frame rate.
¦NoteThe Monarch HDX does not support upscaling the resolution or frame
rate of the input source.
Target bit rate
Enter the target bit rate for your recording (average bit rate).The default
minimum and maximum values (see “Minimum and Maximum Target bit rates”
on page 32) are suitable in most instances, however, you can change the
minimum and maximum values to suit your needs. When entering an average
data rate, the
Minimum and Maximum data rates are automatically set to 90%
and 110% of the target bit rate, respectively. The maximum average video data
rate for streaming or recording depends on the operating mode (see “Monarch
HDX operating modes” on page 29). Monarch HDX uses a variable data rate
when encoding.
Include audio
You must select Include audio to stream/record the selected audio source (see
“Audio Source” on page 26) along with the video. If you want to change this
setting, you must do so before starting a streaming/recording session; otherwise,
you will need to stop the session, make the change, and then restart.
¦NoteMonarch HDX uses the AAC audio format for streaming and recording.
Advanced settings
GOP size
Enter the
GOP size (distance between I frames) to which you want to encode
your input source for streaming or recording.
Remarks
• Monarch HDX uses the IP pattern when encoding for streaming. For
example, a GOP size of 10 creates a GOP structure of IPPPPPPPPPI.
