Pearl Frequently Asked Questions

Pearl simultaneously captures, streams and records four 1080p audio/video sources at 30 frames per second. With dedicated inputs for SDI, HDMI™ and VGA, Pearl captures just about any video content you give it; either directly or with a simple adapter.

How many sources can Pearl capture simultaneously?

We’ve tested Pearl with 4 1080p sources at 30 frames per second and 2 1080p sources at 60 fps.

How many hours of recording can I store?

With 1 TB of onboard storage, Pearl has the equivalent of 260 hours of recording at HD resolution

What is the maximum frames per second (fps) can Pearl capture and stream?

Pearl can simultaneously capture 4 HD sources at 30 fps or 2 HD sources at 60 fps.

Although we don’t have official characterization results for other resolutions, we can provide a rule of thumb. Since Pearl can stream two 1080p streams at 60 fps you can extrapolate that it should handle four 720p streams at approximately the same frame rate (since 720p streams are half the size of 1080p streams). The exact values depend on the load you’re putting on Pearl’s processor.

Does Pearl reduce the resolution of the images it captures?

Pearl by default, preserves the original resolution of the images captured and matches the output frame size of with the resolution of the source. Pearl can also perform real time scaling of the incoming source resolution and render it to the frame size chosen in the stream setup configuration menu. When creating picture-in-picture layouts with two sources, you can change the resolution for each source.

Can Pearl function over a Local Area Network (LAN) or does it need a constant connection to the Internet?

Pearl does not need LAN or Internet connection to do video capture and video recording. Pearl functions as a stand-alone device or connected to the Ethernet port of a computer.

The user-friendly, touch screen displays the video encoder’s stream for confidence monitoring and provides a fast and easy way to apply configuration sets, control recording and view system information. If connected to a a computer by Ethernet cable or to a LAN or the Internet, Pearl provides a web-based control interface for configuration and operation.

The video mode or source resolution that I am using is not listed in the list of supported modes for Pearl.

Pearl’s capture cards analyze the source signals to automatically determine the incoming source resolution. So even if your screen resolution isn’t listed specifically in our tables, it is still supported, as long as it is no larger than the maximum 1920×1200 for DVI, HDMI and SDI and no larger than 2650×1600 for VGA.

Additionally, if Pearl’s video capture process doesn’t automatically match the incoming resolution, you can input a custom resolution through the web interface or upload an EDID to the system.

If Pearl does not support the resolution you provide, please contact us. We are always looking for ways to improve our products to add support for this mode.

How do I configure Pearl?

Pearl’s is ready to use right out of the box! Plug in a source into row A and/or row B and you can capture, stream and record right away!

Fine tuning, stream configuration and video recorder settings are accessed through an intuitive web-based control interface.

The touch screen lets you control switching for Pearl’s video mixer, load saved configuration presets and perform recording control. Advanced users can use Pearl’s HTTP or RS-232 APIs to integrate with larger systems.

Can I use Pearl as an HDMI capture card?

Yes. Pearl has capture cards that are capable of capturing HDMI, DVI, SDI, and VGA inputs. You can capture any HDMI audio and video signal, provided it is not protected by HDCP (High-bandwidth Digital Content Protection).

Pearl will record and optionally stream your captured content.

Is Pearl a video encoder?

Yes, Pearl is a video encoder, and also so much more than that! Pearl is an all-in-one standalone live video production mixer. You can capture, encode, stream and record multiple inputs at once, and even switch between them in a live broadcast.

What compression does Pearl use?

Pearl is compatible with many different video compression formats and codecs. By default, Pearl uses H.264, performed with hardware acceleration, but the video encoder’s codec is user-selectable. Consult the Encoding menu or the Pearl user guide for an up-to-date list of codecs supported by Pearl.

Does Pearl stream to iPad, iPhone, iTouch?

Yes. Pearl uses Apple’s HTTP Live Streaming technology to create a separate native stream for Apple iOS devices such as iPad, iPhone, and iTouch.

Does Pearl stream to tablets and smartphones?

Yes. Pearl supports HLS streaming. When this feature is enabled viewers can access the stream using a tablet or smartphone device. Tablet and smartphone viewers can also view other media streams depending on the device and viewing application.

Can I use my own storage with Pearl?

Yes. Pearl records to the internal hard drive, but these recordings can be automatically transferred to a locally connected USB drive, or to network storage via SCP, FTP, SFTP, RSYNC or CIFS. Additionally, Pearl can act as an ftp server, allowing you to download files directly from the video recorder’s hard drive.

Can Pearl stream to 10-20-100 or more viewers?

Absolutely. Pearl supports a wide range of streaming formats and protocols enabling it to stream video to media players, Content Delivery Networks, multicast networks and Content Management systems.

Pearl can stream to approximately 50 simultaneous unicast viewers without the need for streaming servers, or a CDN. The actual number depends on many factors including encoding format, bitrate, available network bandwidth and network speed.

Pearl is compatible with all major Content Delivery Networks (CDNs) offering a truly scalable streaming solution to millions of internet viewers on various types of devices.

Can Pearl stream to set top boxes and media servers?

Yes. Pearl can stream live to media players, smart TVs, set-top-boxes, digital signs etc. via UPnP or SAP. You can configure Pearl to make videos recorded in MPEG-TS format accessible via UPnP.

Can I customize my stream with my corporate logo, colors, branding. Can I add copyright notices and timestamps to my streams and recordings?

Yes! Pearl has a visual layout designer that lets you build layouts exactly the way you want them.

Combine video capture from your sources with images used for backgrounds, logos and overlays (transparent PNG is supported). Add text or time stamp overlays as well and metadata to the file to tag it with your company name.

What is the difference between Pearl and VGADVI Recorder?

Pearl is a live production video mixer featuring dual HDMI, DVI, SDI and VGA inputs whereas a VGADVI Recorder is a streaming and recording video capture device featuring a single HDMI, DVI, VGA input and an S-video/composite input.

Pearl offers better audio support with audio over SDI and HDMI and balanced audio through TRS audio ports. Pearl can has a more powerful processor that supports video capture and streaming at 60 fps. It has 1 TB of storage. By contrast, VGADVI Recorder offers audio through a 3.5mm audio input, supports video capture at 30 fps and provides 32 GB of internal storage.

Can I crop my video source using Pearl?

Yes. Pearl can crop your video so you can capture, stream and record your video while cropping out confidential information, removing black bars, or using digital crop and zoom to emphasize a specific area of your video!
