Getting Started
Getting started with your Blackmagic Web Presenter HD is quick and easy! All you need to do
isconnect power, connect video and audio, connect the unit to your computer, then connect to
the internet.
Blackmagic Web Presenter HD front panel
Connecting Power
Plug a standard IEC power cable into your Blackmagic Web Presenter HD’s powerinput on the
rear panel.
Web Presenter HD can be powered using the IEC or 12V DC power input
Web Presenter HD also has an additional 12V DC power input. You can use this input if you want
to connect external power or redundancy via an external power supply, for example a UPS or
external 12V battery.
Connecting Video and Audio
Plug your video source into Blackmagic Web Presenter HD’s SDI input. When video is
connected it will be displayed on your web presenter’s built in LCD. Audio is embedded with
the video on the SDI video signal and you can confirm it by observing the audio meters
on the LCD.
Connect video to your Blackmagic Web Presenter’s SDI input
Blackmagic Web Presenter HD supports 12G-SDI and will automatically switch between HD
and Ultra HD all the way up to 2160p60 when the video input changes. This means you can
input virtually any video signal and it will convert down to 1080p.
4Getting Started
Connecting a Monitor
Plug your HDMI television or SDI monitor into one of the monitor outputs. This lets you monitor
your broadcast and observe important status information that updates constantly with your
video stream. For more information on how to use the monitor output, refer to the ‘Using the
Monitor Output’ section.
Connect a monitor to your web presenter’s monitor output
Connecting to a Computer via USB
Connect your Web Presenter HD to your computer using the USB-C port on the front or rear
panel. These USB ports are used for updating the unit and configuring it with the Blackmagic
Web Presenter Setup utility. Once you have configured your Web Presenter for the first time,
you can then disconnect the unit from the computer.
Connect your Blackmagic Web Presenter HD to your
computer using the USB port on the front or rear panel
Connecting to the Internet
Connect your Blackmagic Web Presenter HD to the internet by plugging a network cable from
the ‘live stream’ Ethernet port to an internet router or a network switch.
Connect your Blackmagic Web Presenter HD to your
network via the Ethernet port on the rear panel
5Getting Started
Setting up a Live Stream

change settings.
On Air - To start and stop streaming, simply press the ‘on air’ button. The button will highlight
red while streaming on air.
If the on air button flashes, it means a live stream has failed to start, or has stopped
unexpectedly. This might be due to a problem with your internet connection or streaming
settings. Check that your internet connection is working and your streaming settings
are correct.

8Using Web Presenter HD’s Front Panel
Internet Connection Icons
A blue Ethernet icon is displayed when an Ethernet cable is connected and the
Ethernetconnection will be used for streaming.
A red Ethernet icon is displayed when on air and streaming via Ethernet.
A blue smartphone icon is displayed when a tethered smartphone’s internet
connectionwill be used for streaming.
A red smartphone icon is displayed when on air and streaming via a tethered
smartphone.
TIP If no icon is displayed then your Web Presenter HD is not connected
to the network.
Using the Monitor Output
The monitor output lets you monitor the video input, audio levels, on air status, data rate and
cache levels, plus technical information about the SDI input.
The monitor out on Web Presenter HD provides comprehensive
information including data rate and cache status.
9Using the Monitor Output
The monitor output display is made up of 8 panels. Below is a description of each panel and the
information it displays.
Input View
The main panel displays your current video input from the connected SDI video source.
On Air Status
Prior to streaming, the on air status indicator will display ‘off’ to let you know
Web Presenter HD is standing by and ready to broadcast. When streaming begins,
theindicator will display a bright red ‘on air’ status until streaming is stopped.
Underneath the on air indicator is the duration counter. When you press the on air
button on the Web Presenter HD, the duration counter will start running.
If your Web Presenter HD is off air but will stream via a tethered smartphone, the ‘off’
indicator includes a blue smartphone icon in the corner. When on air, the smartphone
icon will illuminate red.
Live Stream
The live stream panel displays information about your live stream settings. This includes
the streaming platform, server and the first 10 digits of your streaming key. It also
displays the stream resolution and quality settings.
10Using the Monitor Output
Video Input
The 5 mini viewers at the top of the video input panel show the previous 6 seconds of
your live stream, each mini viewer represents 1.2 seconds of streaming time.
Below the mini viewers you can view detailed technical information about the video
input source connected to your Web Presenter HD’s SDI input.
Input Standard Displays the resolution and frame rate of the SDI video input.
Web Presenter HD supports up to 2160p60.
Colorimetry Shows the color space of the SDI video input. Web Presenter HD
suppor ts Rec.601, Rec.709 and Rec.2020 color spaces.
SDI Ancillary Data Ancillary data is data carried in the SDI video input that is in
addition to video. This includes embedded audio, timecode and
closed captions. If your SDI input includes ancillary data then
‘Present’ will be displayed.
Timecode Displays the timecode from the SDI video input source.
Closed Captions If your SDI video input includes Closed Captions the format will be
displayed here. CEA-608 and CEA-708 formats are supported.
SMPTE 292 CRC This is an error checking function for SDI video. If your
Web Presenter HD detects a problem in the SDI video input it will
display an error. CRC errors are usually caused by a faulty SDI cable
or a cable that is too long.
Luminance Y Bits
and Chroma Bits
The indicators for ‘luminance y bits’ and ‘chroma bits’ show you
the activity of the SDI video input signal. Each letter represents the
state of one bit of the video signal.
X - An ‘X’ indicates a constantly changing bit.
L - A low bit.
H - A high bit.
SDI offsets are subtracted to make it easy to understand. For
example, all bits are low when video is black.
Generally, all 10 bits for your SDI video input will show ‘X’ to mean
all the bits on your video stream are changing constantly. If your
SDI input is 8 bit video, the two rightmost bits will always be ‘L’ as
they don’t have any data. If a bit stays ‘L’ or ‘H’ when you expect
itto be ‘X’, this indicates a ‘stuck bit’ and could be the result of a
fault in the upstream video.
11Using the Monitor Output
Audio Input
The audio waveform display at the top of the audio input panel shows the audio
information for the past 6 seconds of your live stream. This is continually updated and
scrolls from right to left.
Below the audio waveform display you can view detailed technical information about
the audio input.
Sample Frequency Displays the sample frequency rate of the audio embedded
in the SDI input.
Emphasis Indicates if your audio source has its emphasis option enabled.
Audio Source Lock Indicates whether the audio source frequency is locked to an
external reference source.
Word Length Shows the bit depth of the audio embedded in the SDI input.
Origin These four characters indicate the channel origin.
Time of Day Free run timecode.
Audio Bits Similar to ‘luminance y bits’ and ‘chroma bits’. An ‘X’ means a
constantly changing bit. If a ‘L’ or ‘H’ is displayed this indicates
a ‘stuck bit’ and may mean the the audio signal bit depth is less
thanexpected.
VUCP Reading VUCP bits from left to right: the ‘V’ bit indicates ‘valid’,
‘U’is the ‘user’ bit, ‘C’ is the ‘checksum’ bit, and ‘P’ is for ‘parity’.
This field is like ‘audio bits’.
Sample Address Audio sample counter.
AUX Bits Use Indicates whether AUX bits are used for main audio.
Audio Channels 1-32 Each digit represents an embedded audio channel on the SDI input.
A ‘P’ shows that an audio channel is in use and a ‘-’ means that
there is no audio on that channel.
