Pearl Mini UserGuide Start here

Start here

Welcome, and thank you for buying Epiphan Pearl Mini™. You'll find all the information you need to set up and start using your system in this user guide. For a product description, see What is Pearl Mini?.

See the Quick start for basic steps to get a single video source (and optional audio) set up so you can stream and record some output right away. The rest of the guide shows you how to tweak the system exactly how you want it so you can take advantage of the many advanced features.

About this Guide

After the introductory section and quick start, the next chapter describes the main user interfaces that are used to operate and configure Pearl Mini. You'll find everything that you need to successfully access and use these interfaces:

l Touch screen

l Admin Panel

l Epiphan Live

The rest of the user guide covers setting up and operating your system for a successful video switching, recording, and live streaming experience. The chapters are organized in to these five categories: Setup,

Capture, Stream, Record and Maintenance.

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 that outputs to SDI, HDMI™, or DVI-I(single link). Capture audio via XLR, ¼ TRS, RCA, 3.5 mm, SDI or HDMI.

Simultaneously capture up to *three audio visual 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.

Pearl Mini does not capture from HDCP encrypted sources.

WARNING: Connecting devices that are not designed for phantom power when phantom power is enabled for the two XLR ports can seriously damage those devices. Always check the phantom power LED before connecting devices to the XLR ports.

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

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.

Pearl Mini UserGuide SD card installation and filemanagement

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 or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.

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.

You can also control recording using the Admin panel or Epiphan Live. For more information about using Epiphan Live, see About Epiphan Live.

To format an SD card and control recording using the Admin panel:

1. Insert the SD card into the SD card slot on Pearl Mini.

2. Using a web browser on the admin computer, go to the IPaddress of your Pearl Mini and log in, see

Connect to the Admin panel.

4. Select either quick disk format or the full disk format, then click Format. Do not eject the SD card while

it is being formatted.

5. From the Channels menu, select your channel (either HDMI-A or HDMI-B) and click Recording. The

Recording page for the channel opens.

Pearl Mini UserGuide Quick start

6. Click Start to start recording the channel and click Stop to stop recording.

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.

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.

There 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.

SD card is reserved for system use and cannot be used to transfer files to other devices, like a laptop. Use a

USB memory device to manually transfer files instead.

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.

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.

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

Pearl Mini UserGuide Vesa mounting the device

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.

Do not insert screws longer than the recommended 5mm. Using longer screws can damage the device.

When you press the start button to activate One Touch recording and streaming, a blue Stop button appears, the Recording values update to show the number of channels and recorders that are actively recording, and the Streaming values update to show the number of channels that are actively streaming.

Pearl Mini UserGuide One Touch streaming and recording control

In the example above, One Touch control has been activated and both channels out of the two total channels and/or recorders are recording successfully. There is no streaming activity because there are no channels configured for One Touch streaming.

An error icon displays if there's a problem with the streaming and/or recording settings for one or more of the channels and recorders. All other channels and recorders that are working correctly continue to stream and record normally.

In this example, after pressing Start, both recorders/channels are recording properly but the one channel configured for streaming is not streaming correctly.

To troubleshoot, investigate each channel's streaming configuration page using the Admin panel and identify which channel isn't streaming. Then correct any streaming configuration errors.

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 configuring multi-track recorders using the Admin panel.

To start recording, simply tap the recording control button for that multi-track recorder. The button turns red when the multi-track recorder is recording and the timer's counter increments. Tap the button a second time to stop recording.

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 Live and the Admin Panel). You must manually refresh the other interfaces separately to reflect the current state.

Network ports used by Pearl Mini

The following table lists the default incoming and outgoing network ports that Pearl Mini uses.

Do not block traffic over these ports. If you want Pearl Mini to operate properly, make sure that your firewall is configured to open these ports. Blocking a port will cause the service that uses that port to fail. It is possible to use the Admin panel to change the default ports that are used for some services.

Table 14 Default incoming network ports for Pearl Mini

Port (or range) Protocol Description

21 TCP FTP server, if enabled. See Local FTPserver.

22 TCP SSH for remote support. See Configure remote support.
