during the stream, such as a

slow internet connection.

9Using Web Presenter HD’s Front Panel

Internet Connection Icons

A blue Ethernet icon is displayed when an Ethernet cable is connected and the

Ethernetconnection 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

connectionwill 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.

10Using 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,

theindicator 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.

11Using 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

supports 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

itto be ‘X’, this indicates a ‘stuck bit’ and could be the result of a

fault in the upstream video.

12Using 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 Shows the bit activity in the audio samples embedded in the

SDI connection. Even if the audio channel status says you have

16, 20 or 24 bit audio, the audio bit activity will confirm it.

VUCP Reading VUCP bits from left to right: the ‘V’ bit indicates ‘valid’,

‘U’is the ‘user’ bit, ‘C’ is the ‘channel status’ 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.

13Using the Monitor Output

Data Rate Display

The data rate display shows the current data rate of of the encoder over the past

60 seconds. The data rate is measured in megabits per second. This indicator runs

consistently, even when off air, so you can accurately gauge your bandwidth before

going on air.

Cache Display

The cache display shows the percentage of Web Presenter HD’s built in memory buffer

that is currently in use and the graph shows the amount used over the past 60 seconds.

The cache is a small amount of internal memory that continuously records and plays the

program output. It acts as a safety measure if the streaming data rate decreases below

a level able to sustain video.

The variable nature of the internet is mostly due to network activity or wireless signal

strength, so if the broadcast data rate decreases, the buffer data will increase

accordingly. If the connection speed becomes slow enough that it cannot support the

video stream, the cache will fill with video frames to compensate. However, once the

cache is 100% full, the video stream will be compromised, so you will want to avoid a

full cache where possible. You can run a test by connecting a video feed and watching

the cache display in the monitor output without having to start the stream. If the cache

frequently approaches 100%, choose a lower quality in the live stream settings.

Audio Meters

You can monitor the levels of your audio source using the audio meters. These can be

set to display either PPM or VU levels in the Web Presenter HD’s menu settings. If your

audio levels are too high the meters will illuminate red and may mean that the audio in

your live stream could become distorted or clipped. Ideally try to keep your audio

towards the top of the green section and occasionally in to the yellow section.

14Using the Monitor Output

Using Web Presenter Setup

When your Blackmagic Web Presenter is connected to a network, any computer connected to

the same network can be used to control your Web Presenter remotely. With Blackmagic Web

Presenter Setup, you can access the same controls and settings that are available on the unit’s

front panel.

15Using Web Presenter Setup

Live Stream Tab

Video Output

Stream Standard

Click on the ‘stream standard’ menu to select the video resolution setting for your

stream. Youcan choose from 720p25 up to 1080p60.

Settings

If you have custom streaming settings, for example an XML file from a Blackmagic

ATEM Streaming Bridge, you can import them by clicking the ‘load streaming

settings’ button.

For more information on creating custom settings and connecting to ATEM Streaming

Bridge, refer to the ‘Creating Video Links with ATEM Streaming Bridge’ section later in

this manual.

Live Stream

Platform

Click the ‘Platform’ menu to select the streaming platform for your broadcast. Options

include YouTube, Facebook and Twitch. If you have imported custom streaming settings

they will also appear in the platform list.

Server

Select the server that is closest to your location by selecting it from the list. The server

list will vary depending on your chosen streaming platform.

Key

Enter the streaming key that has been assigned to your broadcast from the

streaming platform.

Quality

Select the streaming quality:

• HyperDeck High 45 to 70 Mb/s

• HyperDeck Medium 25 to 45 Mb/s

• HyperDeck Low 12 to 20 Mb/s

• Streaming High 6 to 9 Mb/s

• Streaming Medium 4.5 to 7 Mb/s

• Streaming Low 3 to 4.5 Mb/s

The data rate used by the quality setting will change depending on the video standard

Web Presenter HD is using. For example, if you select ‘streaming high’ quality and are

running at 1080p24 then it would use the 6 Mb/s data rate.

The data rates used on HyperDeck High are 45 to 70 Mb/s, the rates for HyperDeck

Medium are 25 to 45 Mb/s and the data rates used for HyperDeck Low are 12 to 20

Mb/s. The streaming data rates are lower to allow for transmitting the data over the

internet, so the data rate for Streaming High is 6 to 9 Mb/s, the data rate for Streaming

Medium is 4.5 to 7 Mb/s and the data rate for Streaming Low is 3 to 4.5 Mb/s.

You will notice that each setting has 2 data rates mentioned. The lower number is used

for the lower frame rates of 24p, 25p and 30p, while the higher data rates are used

when you are running higher frame rates of 50p and 60p. It’s also worth noting that the

default setting for the streaming quality is Streaming High 6 to 9 Mb/s, as this gives a

very high quality streaming channel.

17Using Web Presenter Setup

Reset

Reset your Web Presenter HD by clicking the ‘factory reset’ button.

Network Settings

Your Web Presenter HD can connect to the network using a static IP address or by using DHCP.

DHCP - will automatically set an IP address for your unit and connect it to your network without

any settings changed.

The dynamic host configuration protocol, or DHCP, is a service on network servers and routers

that automatically finds your Web Presenter HD and assigns an IP address. DHCP makes it easy

to connect equipment via Ethernet and make sure that IP addresses do not conflict with each

other. Most computers and network switches support DHCP.

Static IP - If you want to set the IP address yourself, simply set the protocol setting to ‘static IP’

and change the IP settings manually.

A static IP address is one that won’t change even if your Web Presenter HD is rebooted.

Using a static IP address might be necessary if your connecting your Web Presenter HD to a

corporate network. If you have a network administrator, it’s possible your network might have

custom IP addresses for all the equipment connected to it. It’s best to check with your network

administrator if they are managing your computers and network in your company.

Setting Internet Sharing
