Skehan Communications, a leading video production and transmission company provides multi-camera HD video production, webcasting, satellite uplinks and other unique services to broadcasters, Fortune 500 companies, professional associations and government agencies. Though based in the Washington-Baltimore region, their projects have taken them to many impressive locations from San Francisco to Boston.

Specializing in remote, multi-camera HD field production, the company covers all types of events and shows. Recent events include:

Horatio Alger Association Awards & Induction Dinner

Howard Hughes Medical Institute Holiday Lectures on Science

US Conference of Catholic Bishops Annual General Assembly

ESPN's Baseball Tonight

History Makers & PBS: An Evening With Gwen Ifill

Opera House Live: Dr. John Concert for the Smithsonian Channel

Interludes DC: Jill Scott for the TV One network

OTAKON 2015 Convention of anime' afficionados

The company prefers to own its equipment and facilities so seldom relies on outside sources. Its eight-camera mobile production truck, named Kiwi , is readily adaptable to any kind of HD television production requirement, thanks in part to its multi-camera recording system based on the Matrox VS4 quad HD-SDI capture card and the VS4Recorder Pro software.

The Drive for Change

Before integrating the Matrox-based system into their equipment arsenal, the production truck already had six disc-based media recorders. Then one client had a specific need to record eight camera feeds as well as two program feeds, increasing the requirement to ten recording channels. At a cost of approximately $3600 per recorder, adding the extra capacity with more of the same recorders was not an affordable solution and wouldn't offer the desired operational flexibility and ease of retrieving and moving files around.

Mike Skehan, CEO of Skehan Communications was on the lookout for a capture card on which to base a multi-channel HD recording server. The solution had to be financially practical and at the same time not make the operational workflow overly complex.

Plus, Skehan saw the growing need for redundant recordings at varying bitrates using a variety of codecs. He wanted to get the most versatility and efficiency for as small a cost as possible. The company had already transitioned away from video tape recorders (VTRs) to file-based workflows for recording and playback. Now it was time to find a more efficient and affordable solution to meet clients' needs.

Solution Discovered

After exploring several hard drive-based options, Skehan found a few custom recorders that suited the need, but at a cost of about $5000 per recording channel. Then he came across Matrox VS4. The VS4, with its VS4Recorder Pro software and VS4Control feature, seemed to hold the promise of an affordable solution, said Skehan. It had everything needed to record HD video for multiple channels.

When Skehan Communications tackles a show, there are often varying recording needs to be met. The most basic is to record a main program along with a program backup. However, many clients want their main camera, and perhaps others, recorded as isolated (ISO) feeds. This covers them in case of a misstep in the program switching. ISO recordings are also used in post-production to produce varying versions of the event. In the Skehan truck, all recorders have routable inputs, so the VS4 recording server's four channels can be used for any source coming into, or generated by, the truck.

A necessity of recording is the ability to share a common time code across all the equipment. VS4Recorder Pro offers three options for master time code set up - Embedded SDI, System Time, or Time of Day. The system Skehan built uses an external GPS-based time code generator to reference their server's system clock, so every recording has exactly the same time code.

One of the larger shows Skehan Communications has covered is the annual Horatio Alger Awards & Induction Ceremonies dinner held at the DAR Constitution Hall to honor new members. This is an organization of philanthropic individuals whose mission is to promote and fund higher education for disadvantaged students. This remote production typically entails four days of work: two days of set up, a day of rehearsal, and the show day. In previous years, only a few selected feeds could be ISO recorded and that proved inadequate when it came time to edit after the event. This year, ten cameras including two robotics were used and all feeds were ISO recorded. In addition to the ISO recordings, two program recordings were done. VS4Recorder Pro made it easy to meet all the recording requirements synchronously so the show was covered in its entirety without missing anything.

Workflow and Benefits

Having four HD recording channels in a networked 4RU server chassis, the ability to record to multiple codecs, in varying bitrates, and the capability to record to a wide variety of storage devices - including to a RAID (redundant array of independent disks) - has made the production process a lot easier for Skehan Communications and its clients. The new workflow, with the redundancy offered by the RAID, provides an added measure of securi
