Pearl User Guide What is Pearl? What is Pearl? Pearl, our most versatile live video production switcher, is a video encoder, video streamer, live switcher and video recorder that comes in three models. All three models have the same functionality, and this guide applies for all three models. Where used in this guide, the product name Pearl is interchangeable for Pearl Rackmount or Pearl Rackmount Twin, except in a few cases where physical differences are explicitly called out.

PART 2: Capture Capturing is the process of taking the signals from your video and audio sources and encoding them in a format that is ready for streaming and recording. If you followed the quick start guide, you're already capturing, streaming and possibly recording your sources. The section of the guide helps you fine tune and troubleshoot the capturing process. When using Pearl, you can stick to all the default capture and encoding settings, or you tweak them to set the up exactly as you like.
Pearl User Guide What is a channel? What is a channel? Pearl uses Channels to organize and display content captured from HDMI, DVI, VGA, SDI. Channels make your sources (HDMI, DVI, VGA, SDI) available for streaming and recording. You choose how you want to configure your sources (and extras like images and text overlays) into layouts within your channel. Pearl gives you a lot of control over how your sources are streamed.
Pearl User Guide Use the automatic channels Auto A and Auto B Through channel configuration and fine-tuning you can maximize your stream quality, minimize your processing requirements and bandwidth. You can also specify how the video is presented and streamed to sharing destinations and viewers.
Pearl User Guide Know which signal is used for Auto-A or Auto-B Default audio setup for the auto channels is always as follows: Video Source Audio Source SDI SDI Audio HDMI (DVI) HDMI Audio (no audio for DVI) USB video USB audio VGA TRS Audio You can start viewing the channel immediately on the touch screen display (if enabled) or by using an internet browser on the same LAN or network. Browse to the following URL: For Auto A: http://.local/preview.
Pearl User Guide Configure auto channels Priority Connector Type 1 HDMI (with HDMI Audio) 2 SDI (with SDI Audio) 3 VGA (with TRS Audio) The auto channel uses a source until the source has no signal, then switches to the highest priority signal found. For example, if you attach SDI, then VGA and TRS cables to Row A of your Pearl, Auto A will show SDI and use SDI audio until such time as the SDI video signal is lost or you use the audio input selection option in the sources section.
Pearl User Guide Create a simple channel 5. Configure the channel as you would any other channel. See below. You can change the source used for the two auto channels by selecting a different source from the layout editor in the Sources page. When you do this, the channel name changes to reflect the new source (if that is the only source is used for the channel). No auto switching is performed.

Limitations and known issues This section includes known issues or limitations that affect functionality or usability and ways that you can work around these limitations. Important notes about upgrading from firmware older than 3.16.0 1. In release 3.16.0, configuration presets replaced the concept of backup files. These new files use a new format to accommodate portability between systems. As a result, backup files from previous versions (prior to 3.16.0) cannot be loaded on systems running firmware 3.16.
l For VGA sources only, some wide-mode resolutions are not correctly identified and result in a slightly squished image (e.g. for a 1360x768 source, the detected resolution may be 1024x768). Workaround: This issue is related to the video source. Test your source to see if it exhibits the issue. If possible, avoid using wide-mode for VGA sources that exhibit this issue. l Encoding video at 60 fps with either 16 kHz or 22 kHz AAC audio can result in some dropped video frames.
Affecting the Admin panel l It is possible to name two or more channels with the same value. Use of automatic file transfer and UPnP is unpredictable if this occurs. Workaround: Ensure each channel has a unique name. l The automatic file upload (AFU) file queue shows a maximum of 15 files, Newer 15 and Top of the list buttons do not work. All files are transfered, even though they are not listed. Workaround: Wait for the queue to have fewer files in the list.
l Some monitors, when attached to one of the video output ports, prevent the system from restarting properly after a software initiated reboot. (This was observed with a Samsung 4K monitor.) Workaround: If you observe this problem, use the hardware button for shutdown and startup or disconnect the monitor during reboots. Affecting USB devices l For the Microsoft® LifeCam Studio web camera, changing any settings during the video while the Powerline frequency is set to 60 Hz causes the stream to end.
