background graphic, which many competitive
In the Video section in Figure 2, you see the
I/O selectors. Input A, which is designed to be
the talking head, can be either HDMI or SDI,
while HDMI is your only option for the second input. Again, the second input is designed to come
from a computer. As you can see, you control
what’s pushed through the SDI and HDMI output ports; I found the channel preview to be the
most helpful view. On the right, you choose the
audio source and the sample rate and bitrate,
though you can only choose audio from a single
source, and there are no volume adjustments.
Figure 4 shows the two output channels: One
is configured for Ustream, the other for recording. When running a single encoder in streaming mode, you can stream at up to 16Mbps.
When running in dual mode, you can stream
at up to 8Mbps, and record at up to 10Mbps.
Matrox offers multiple presets for both recording and streaming, which you can tweak using
the advanced settings shown in the figure. All
streaming and recording are encoded using
H.264, which you can record in either an MOV
or MP4 wrapper. All recordings have a maximum length of 300 minutes.
Enter your streaming coordinates as you do
with most encoders, copying and pasting the
long server URL and stream name from your service provider, and entering your username and
password. You can also load a Wowza Streaming Engine or Adobe Flash Media Live Encoder
XML file for those services that provide them.
As with the other Monarch products, there
are some rough edges in the software. For ex-
ample, there’s no way to check if your encoder
settings actually work before trying to go live,
a feature that the venerable Flash Media Live
Encoder has provided for years. You also can’t
check if the Monarch can write to your SD card
or USB hard drive without clicking over to the
We raised these issues in our October 2015
review of the Matrox Monarch HDX ( bit.ly/2d4
qrFh), which uses much of the same software.
It’s frustrating that these issues haven’t been
On the other hand, Matrox has committed
to an aggressive development program for additional features. For example, by November,
you should be able to automate operations via
a schedule in an iCal-compatible format that
you can load manually, or place in a path that
the unit can periodically retrieve. Speaking of
scheduling, via the unit’s API, you can already
auto-schedule events with third-party CDNs Ensemble Video, Presentations 2Go, and Stream-Shark. Matrox will also support Kaltura’s Open
Video Capture Standard, which will provide immediate integration with Kaltura and other programs that support the standard. Matrox also
plans a store and forward feature for uploading recorded feeds to network storage during
off hours to preserve corporate bandwidth.
Testing the Monarch
Beyond configuration testing with the Monarch, we produced a 1-hour video to test stability and sync, recording one stream and sending
the other to You Tube Live. While certainly not a
torture test by any means, Monarch performed
perfectly in these trials, and we find comfort that
the hardware has been well proven.
We also recorded a video tutorial
( bit.ly/2di4ld9) showing the configurations and options discussed herein;
that’s the screen shown in Figure 3. To
test the stream variability of the recorded video, we input the video into Bitrate Viewer, revealing the CBR
stream shown in Figure 5 on page 78.
Assuming the streaming output is as
consistent as the recorded videos,
getting Monarch streams out of the
building or over the network should
be as efficient as possible.
Overall, the Monarch LCS provides all the essential features for
