Pearl Mini UserGuide What is PearlMini?

What is Pearl Mini?

Pearl Mini is a versatile live video production device that's a video encoder, video streamer, live switcher, and
video recorder all in one. Pearl Mini is great for lecture capture applications.

With Pearl Mini, you can capture, record and stream computer monitors, radar displays, or anything with a
wide variety of supported video input signals, including:

l SDI

l HDMI™

l DVI-I(single link)

l USB

l RTSP

Capture audio via XLR, ¼ TRS, USB, RCA, 3.5 mm, SDI or HDMI.

Simultaneously capture up to *three audiovisual sources and choose how you want to record and stream
them. Have separate ISOs or create custom layouts with multiple video sources for live switching. You can do
all that using Pearl Mini.

Easily watch live streams using your favorite web browser or media player on mobile devices and computers
connected to the same private network as Pearl Mini or using Content Distribution Networks (CDNs).
Recorded files can be downloaded via FTPor set to automatically upload over FTP, RSYNC, or CIFS and can be
integrated into your Content Management System (CMS). Pearl Mini is also fully integrated with Kaltura CMS
and can be registered as a video encoder resource for easy lecture capture.

Network security compliance with 802.1x protocols, passwords, and certificate authentication means an
easier setup for IT friendly live streaming over enterprise networks. HTTPS enabled for secure administration
and control over the LAN, and RTMPS support for secure, encrypted live streaming.

SD card installation and file management

Pearl Mini comes with a standard SD card slot on the front panel. An SD card is needed when recording video.
If you're only switching video or live streaming, then you don't need to install an SD card.

We recommend using a minimum class 10 (C10) SD card that's at least 64 GB capacity but does not exceed
512 GB; however, most SD cards that are at minimum a C10, a UHS class 1 (U1), or a video speed class 10
(V10) should work. We've tested various SD cards with Pearl Mini, including:

l Kingston 16 GB U1 / C10

l Sony 32 GB U3 / C10

l SanDisk 64 GB U1 / C10

6

Pearl Mini UserGuide SD card installation and filemanagement

l PNY 256 GB U3 / C10

l AData 128 GB U3 / V90

When the SD card is full, new recordings overwrite the oldest recordings. Do not eject the SD card while
recording is in progress as that may corrupt the SD card.

The SD card must be EXT4 formatted for the Ubuntu operating system. You can format the SD card using the
Admin panel, see Format the SD card.

The Ubuntu formatted SD card cannot be used to transfer files to iOS or Windows systems. Any
content that's contained on the SD card is lost when the SD card is formatted.

For important considerations when setting the maximum file size limit and recording to the SD card, see

About recording.

Pearl Mini UserGuide Quick start

Quick start

Pearl Mini comes shipped with a power supply and cable, a quick start guide, and a registration card. After
you've unpacked your Pearl Mini, you're ready to get started. This quick start uses the default settings where
possible so you can quickly start using your Pearl Mini.

Before you begin, make sure you have:

l a video source such as a camera or computer and cables to connect them to Pearl Mini. For HDMI, the

video source must not be HDCP protected.

l an audio source coming from either your SDI , USB videoorHDMI video source (must not be

encrypted). Optionally, audio from a different source, such as an audio mixer or microphone that you
connect to the audio input ports can be used.

l Local area network that uses Dynamic Host Configuration Protocol (DHCP) is preferable.

l Computer with a web browser connected to the same network. We'll call it the “admin” computer.

l (Optional) A formatted SD card if you plan to record video using Pearl Mini. We recommend an SD card

that is at least a class 10 with up to 512 GB of capacity. The SD card must be EXT4 formatted, see SD

card installation and file management.

Starting up!

Pearl Mini is pre-configured with two channels: HDMI-A and HDMI-B. The HDMI-A video input port on Pearl
Mini is assigned to the HDMI-A channel and the HDMI-B video input source is assigned to the HDMI-B channel
by default.

When you first start your Pearl Mini, the video sources you've connected to the HDMI-A and HDMI-B input
ports appear automatically in their assigned channels, along with the associated HDMI audio. If no video
source is connected, a standard No Signal screen displays.

The channel's frame size is set to match the video source by default and the best bit rate for the
default frame rate of 30 fps is applied to the channel automatically. Audio for the channel comes
from the video source that is connected to the HDMI port by default.

1. Turn on your camera or video source and connect the output to the HDMI-A input port on the back

panel of Pearl Mini.

2. (Optional) Connect a second video source to the HDMI-B port.

3. Connect the Ethernet cable to Pearl Mini and to your network.

4. Attach the power cable and plug it into a power source.

8

Pearl Mini UserGuide Quick start

5. Press the power button on the back of Pearl Mini to turn on the system. Wait for the power-up cycle to

complete.

The Grid view showing both channels appears on the touch screen. The video source you connected to
the HDMI-A port appears in channel HDMI-A, and the video source connected to the HDMI-B port
appears in channel HDMI-B.

6. Use the touch screen on Pearl Mini for confidence monitoring. To display the single Channel view,

simply tap on one of the channels that you see in the Grid view. From the Channel view, you can do
things like stop and start recording for the channel.

7. (Optional) Plug speakers or headphones into the 3.5 mm headphone jack at the front ofPearl Mini. For

more about monitoring audio, see Monitoring audio.

My network IPaddress and channel monitoring

You can get the network IP address of your Pearl Mini from the touch screen so that you can do things like
view the channels using a web browser or access the configuration Admin panel. Just make sure that your
admin computer is connected to the same network as Pearl Mini.

1. To find the IP address using the touch screen, tap the gear icon in the bottom right corner of the

screen and select System Status. If the control icons aren't displayed, tap anywhere on the touch
screen.

Pearl Mini UserGuide Quick start

2. Using a browser on the admin computer, go to one of the following URLs to preview the channel.

For HDMI A:http://<IP Address for Pearl Mini>/preview.cgi?channel=1
For HDMI B: http://<IP Address for Pearl Mini>/preview.cgi?channel=2

For example:http://192.1.10.100/preview.cgi?channel=2

3. (Optional) Open a new tab in your browser and enter the URL to login to the Admin panel.

http://<IP Address for Pearl Mini>/admin

For example:http://192.1.10.100/admin

The default user name admin has no password set by default. If a password has been set, consult with your
system administrator for the login credentials, see User types and privileges. For Admin panel login details, see

Connect to the Admin panel.

Install a formatted SD card to record a channel

An SD card must be installed and formatted before you can record video using Pearl Mini. You'll need to log in
to the Admin panel using the IP address of your Pearl Mini to format the SD card, see Format the SD card.

After the SD card is installed and formatted, it's easy to start recording your channel from the Channel view
using the touch screen. Just tap the red dot that appears in the top right corner of the screen to start and stop
recording the channel. The dot flashes while recording.

Pearl Mini UserGuide Quick start

Recordings are saved to the SD card by default. You can not manually transfer recordings off the SD card to
iOS or Windows systems. Download recordings using the Admin panel. For other options, like downloading to
a USB memory device or using Automatic File Uploads, see FTP and automatic file transfers.

Ejecting the SD card while the recording is in progress may corrupt the SD card and cause loss of
data. Stop all recordings before powering down the system.

Pearl Mini UserGuide Monitoring audio

Monitoring audio

Pearl Mini's front panel includes a 3.5 mm audio jack for monitoring audio. You can plug external speakers or
headphones into the 3.5 mm audio jack. To monitor the audio for a channel, just select the channel using the
touch screen. The audio you hear depends on which layout is currently live because different layouts can have
different audio sources configured.

Adjust the volume

Tap the headphones icon on the touch screen to adjust the volume. Each tap increases the volume by 25% to
a maximum volume of 100%. Tapping the headphones icon when the volume is at 100% mutes the volume.
You can also long press the headphones icon to mute and unmute the volume.

Volume is muted.

At 75% volume, what you hear corresponds to the nominal audio level in the VU meter at approximately
where the green bars change to yellow. Increasing the volume to 100% may cause you to hear distortion that
is not actually present in the audio signal being recorded and streamed.

Pearl Mini UserGuide Selecting an audio source

l Admin Panel: On the audio input source's configuration page when you select the input source from

the Inputs menu. You can also add the VU meter to appear on the video output ports, see Disable or

enable audio and output port volume.

l Epiphan Live: See Monitor video and audio input sources

Selecting an audio source

The audio that's coming from the connected HDMI video sources (HDMI-A and HDMI-B) is automatically used
as the default audio source for the HDMI-A and HDMI-B channels on Pearl Mini. You can choose different
audio sources for a channel using the Admin panel and do things like adjust the input gain, see Adjust audio

gain and delay.

Select your audio sources from connected video sources (SDI, HDMI, USB video UVC, and RTSP), as well as
from the dedicated analog audio input ports. The USB (UVC/UAC) ports on the rear panel of Pearl Mini will
accept a USB microphone (UAC).

Dedicated analog audio inputs ports are:

l Two XLR/TRS combo jacks.

l XLR mic-level input (balanced), supports 48 V phantom power

l TRS ¼" professional line-level input, + 4.0 dBu up to 12.3 V RMS, (+24 dBu)

(balanced/unbalanced)

l One 3.5 mm stereo mic level input for electret microphones (unbalanced)

l One stereo pair RCA consumer line-level input (-10 dBV)

The XLR and TRS combo jacks are configured as a left/right stereo pair by default, see Configure audio ports

for stereo or mono. The 3.5 mm audio ports and the RCA audio ports are linked. You can configure Pearl Mini

to use both or just one of the audio sources using the Admin panel, see Assign audio sources to an input.

This table offers some guidelines for adjusting the gain of the audio input ports for common types of audio
devices. You should add the suggested gain to the audio input to get an average signal to register at a nominal
level in the VU meter (i.e. where the green bars change to yellow). The actual amount of gain needed depends
on the strength of the original audio signal.

For best performance, we recommend using two video sources in up to two full HD channels simultaneously.
However, you can connect up to three video sources to Pearl Mini in the following scenarios:

1. One 1920×1080@30 fps channel configured with three layouts, one for each full HD video source

without any scaling and make the video image fill the whole frame.

2. Two 1920×1080@30 fps channels: one channel for a picture in picture switched program for HD

recording at 1080@30 fps at 8 Mbps, and a second channel with duplicate content at a lower
resolution of 720@30 fps at 2 Mbps for streaming that uses the first channel as the video source, see

Add video sources or a channel as a source. The switched program can have up to three layouts: two

that are picture in picture that includes your main camera and one other video source such as a
document camera or a laptop with slides, and a third layout of your main camera.

One of the video sources you connect can be either a USB or an RTSP source; however, you cannot connect
both at the same time. Pearl Mini supports connection of common signal converters and input adapters.

Optimum CPU performance

Pearl Mini is a powerful live video production system; however, there's a limit to the number of concurrent
tasks the onboard CPU can perform efficiently.

The number of concurrent tasks depends on many factors, like: how many channels you have, how many
layouts you have per channel, how often you switch layouts, is the system resizing (scaling) video sources,
what frame rate and bit rate is used per channel, are the video output ports used, etc. Keep in mind that
connecting a live monitor to the HDMI output port consumes about the equivalent of an encoded
1920×1080@30 fps channel.

For best results, we recommend keeping Pearl Mini's CPU usage under 70%.

You can check the Overall system load from the Info page using the Admin panel.

25

Pearl Mini UserGuide Vesa mounting the device

To check the CPU usage from the touch screen, tap the gear icon and select System Status.

If the system load is higher than recommended, you can:

l Disable the video output port (if unused).

l Remove unused channels or layouts.

l Reduce the number of channels created.

l Ensure video sources come in at the right resolution so that Pearl Mini doesn't have to up scale or down

scale the video source.

Vesa mounting the device

The rear panel of Pearl Mini has vesa mounting holes to fit a standard, 75mm × 75mm vesa mount. Use four
M4 screws with a maximum length of 5mm to mount the plate to the rear panel of Pearl Mini.

26

Recording using multi-track recorders

From the Admin panel, you can create multi-track Recorders to capture multiple channels and audio sources in
a single recording. You can then select which combination of video and audio sources to extract from the
recording. This feature is useful when you're capturing a video source and multiple languages from different
audio sources. Multi-track recorders appear on the Dashboard if they are configured on your Pearl Mini.

Each multi-track recorder has a recording control button to start and stop recording. When a Recorder is not
recording, the button is gray and the timer is set to 00:00:00. See Add a recorder to learn more about

Switching / mixing using Epiphan Live

The Live Switcher view in Epiphan Live is a simple interface that lets you live switch between layouts while
streaming and recording. To learn how to create different layouts for a channel using the Admin panel, see

Add or edit a custom layout.

Switching between layouts using one of the switcher interfaces, such as the touch screen,
does not dynamically update what you see in the other switching interfaces (i.e. Epiphan

About using AV Studio to control Pearl Mini

AV Studio is a cloud-based video production platform that lets teams remotely control video encoders like
Pearl Mini. Using AV Studio, you can control recording and do quick, low touch editing for fast turn around
and cloud delivery of recorded conferences, break out room sessions, seminars, and more.

When Pearl Mini is paired with AV Studio, you can:

l Preview channels remotely.

l Start and stop channel recording directly in AV Studio.

l Upload and post process recordings using the AV Studio Scene Editor. Some costs are incurred when

uploading recordings to a pay-as-you-go AV Studio account.

l Render and share recordings with others from the cloud.

l Change video and audio encoding settings for a channel.

l Access cloud versions of the Admin panel and Epiphan Live for remote login and control, see Access

cloud versions of the Admin panel and Epiphan Live.

For more information about AV Studio, see the AV Studio online user guide.

Important considerations

l Channels that you record directly using AV Studio are not saved to the same location as recordings you

make for the channel using the Admin panel or Epiphan Live. The AV Studio upload queue is accessed
from the AV Studio page using the Admin panel.

l Until the recordings are uploaded to AV Studio, they are available for downloading to a locally

connected admin computer. After recordings are uploaded to AV Studio, they are no longer available
locally on Pearl Mini.

l Recordings do not automatically upload to AV Studio by default. You can manually start uploading

using AV Studio. Once uploading is enabled, recordings continue to upload automatically until you
select stop uploading.

l Some costs are incurred when uploading recordings to a pay-as-you-go AV Studio account.

l The following actions cause Pearl Mini's encoder entry in AV Studio to permanently go offline. You must

previously created for a Pearl Mini encoder instance that is permanently offline in AV
Studio. Deleting an offline encoder instance in AV Studio removes all uploaded recordings
and scenes that were created for that encoder.

Select channels for remote control

When Pearl Mini is paired to AV Studio, up to four channels configured on Pearl Mini are automatically listed
on the AV Studio status page in the Admin panel. The listed channels can be remotely controlled from AV
Studio just like separate encoders for as long as Pearl Mini is paired.

You can easily change which channels are listed and deselect channels to prevent them from being remotely
controlled using AV Studio.
