Epiphan Pearl Rackmount Twin Live Production Video Mixer

by Epiphan Video

The Epiphan Pearl Rackmount Twin is comprised of two completely independent Pearl live production video mixer systems, with double the inputs and outputs, in a 2 RU form factor. The Pearl Rackmount Twin lets you efficiently capture, switch, stream, and record video. With advanced automatic channel creation and two front panel touchscreen displays, setup is very simple. Simply plug in power and one or two sources to see your captured stream on the displays, connect to a network, and start streaming right away.

In comparison to the portable Pearl, the Pearl Rackmount Twin also features an integrated power supply and two USB ports on the front panel (one for each integrated unit) in addition to the USB ports on the rear. The Pearl Rackmount Twin also has two 512GB SSDs (one per unit), each of which will store approximately 150 hours of HD recordings.

With the Pearl Rackmount Twin you can capture four HD sources at the same time via SDI, HDMI, and VGA inputs on each integrated Pearl. You can also use optional adapter cables to capture from DVI and component sources. Audio is captured embedded in SDI and HDMI sources and can also be captured independently via on-board stereo TRS jacks.

The Pearl Rackmount Twin is capable of recording your videos while at the same time outputting up to four 1080p streams at 30 fps, or two 1080p streams at 60 fps from each integrated unit. You can also output a single Ultra HD 4K (3840 x 2160) stream at lower frame rates from each unit.

The multi-featured front panel touchscreen displays can be used for live switching, confidence monitoring, quick configuration, system information, recording control, and streaming control. They can also display a VU meter with quasi-peak metering. In addition to the touchscreen displays, two Mini DisplayPort connectors are also available per unit for local video output with audio, for confidence monitoring.

Since the Pearl's original release, Epiphan has continuously enhanced it via firmware upgrades. The quasi-peak metering feature mentioned above, for example, was added to the Pearl via such an enhancement. Accordingly, more enhancements may additionally be made in the future.

Live Event Streaming
Capture ISOs in Full Detail
Stream your content picture-in-picture, in the supported resolution of your choice, while also recording original, high-quality ISOs for post-processing. For high-density solutions, Epiphan suggests using the Pearl Rackmount Twin with one embedded Pearl doing streaming and the other dedicated to recording ISOs.

Capture Four HD Sources from Each Pearl Unit at Once
With built-in support for 3G/HD/SD-SDI, HDMI, and VGA, as well as DVI and component via optional adapter cables, Pearl Rackmount Twin can capture just about any video source you have. Audio capture is supported over HDMI and SDI and through stereo TRS audio jacks.

Auto or Custom-Configure
Let Pearl Rackmount Twin set everything for you automatically, or take advantage of the web UI to configure bit rate, frame size, layouts, overlays, and more.

Stream to Your Viewers
Stream to local viewers using browsers or media players, or use Pearl Rackmount Twin's CDN integration to share with a large audience. You can even stream to smart TVs and set-top boxes. Have as many as four different 1080p streams at 30 fps, all from one device.
Quality Monitoring
Monitor Video
Pearl Rackmount Twin features a touchscreen display for each integrated Pearl unit. Each touchscreen lets you scroll through your channels (also known as video streams) to monitor what's being captured, streamed, and recorded.

Monitor Audio
Use the front-mounted 3.5mm mini audio jacks to plug in speakers or headphones for audio monitoring. The touchscreens also display a VU meter to guide decisions regarding audio levels.

Multi-Feature Touchscreens
Not only do the touchscreens let you see what's being streamed, you can also use them to load saved configuration settings, control recording, and switch video layouts in a stream with the touch of a finger.
Create Engaging Video Streams
Arrange Content into Layouts
Use the web UI to arrange your sources into fully configurable layouts. Add pictures, even transparent PNG files as backgrounds, logos, or overlays. Optionally add date and time stamping or other text to the layouts.

Switch Video Sources Live
Use Pearl Rackmount Twin's touchscreens and video mixer capability to preview and change the content in your video stream. Pick from any of the predefined layouts you created to keep your audience engaged and show them exactly what is relevant.

Record Captured Streams
Record an HD copy of your captured video stream, as well as the individual sources, so you'll always have what's needed for professional post-processing.
Quick Configurations
Save Your Configuration
Pearl Rackmount Twin lets you save your current configuration as a preset you can recall later. Save network settings, channel setup and layouts, even streaming settings.

Apply Presets Later
Pre-create presets for all the situations in which you'll do video capture, streaming, and recording with Pearl Rackmount Twin. Use the touchscreens or web UI to load a saved configuration when you arrive on location or between events.
Multiple Stream Options
Stream Locally or to Set-Top Boxes
Use unicast or multicast to stream locally to up to 50 viewers. Pearl Rackmount Twin supports a variety of live streaming formats to stream video to media players and web browsers using industry standard streaming formats, including HTTP, FLV, ASF, MJPEG, and HLS. It also provides UPnP and SAP sharing to stream to smart TVs and set-top boxes.

Stream to CDNs
Publish your live video stream to a large audience using an enterprise streaming server or CDN using RTMP and RTSP. Want to use two CDNs or stream to both a CDN and an enterprise server? No problem. Duplicate the channel and publish the same stream to both places simultaneously.
HD Video Quality
H.264, MPEG-4, or MJPEG Encoding
For maximum compatibility with video players, Pearl Rackmount Twin's default video codec is H.264, backed with hardware-accelerated encoding. You can also choose from MPEG-4 or M-JPEG.

Fully Synchronized Sound to Video
Using incoming signals over the HDMI, SDI, or TRS ports, Pearl Rackmount Twin embeds encoded sound into your video stream. Use the default AAC audio at 320 Kb/s, or select from AAC, MP3, or PCM audio with stereo or mono, with bit rates from 32 to 320 kb/s and sampling at 22 to 48 kHz.
Maximize Value with Video Recording
Record with or without Streaming
Each channel has recording control independent from streaming control – do one or both simultaneously, your choice. Pearl Rackmount Twin also has configurable video recorders that group multiple streams together for synchronized recording.

Play Files Anywhere
Pearl Rackmount Twin records in MOV, AVI, or MPEG-TS format. You can configure how large or how long the files are before a new file starts, and you can configure the filename prefix.

Recordings Remain Safe
The Pearl Rackmount Twin features two 512GB SSDs, each capable of holding almost 150 hours of HD recordings. You can also configure automatic file transfer to a local USB drive or to a network drive using SFTP, FTP, RSYNC, SCP, or CIFS.
Work with What You Have
Control Pearl Rackmount Remotely
Pearl Rackmount Twin has a comprehensive remote command set available over HTTP and RS-232 so you can configure and control nearly every aspect remotely.

Multiple Control Options
You can control Pearl Rackmount Twin from your desk, on the go, or sitting in front of the Pearl Rackmount Twin. Perform the initial configuration through the web UI, but once that's complete you can use the touchscreen for quick configuration and live video switching, the tablet web UI for status and recording control, the full web UI, or a custom third-party app made using Epiphan APIs.
