Product Notes & News

Magewell NDI Decoders started shipping as of IBC 2019

The first in the range of Pro Convert NDI decoder units, the NDI to HDMI is priced at 350 GBP and has a host of features including a built-in scaler to match NDI resolutions up to 4K to HDMI devices, again up to 4K (although this is not a "full 4K" unit, so frame-rates are limited when decoding 4K NDI). Other features include optional output overlays of audio meters, ident text, tally, markers and an on-screen menu for changing settings, controlled from two buttons on the side of the unit or a connected keyboard or mouse. Audio levels and channel remapping can be set, and the image flipped in either direction for prompting/projectors when needed. More info on the Magewell website or come for a demo.

On show at ISE 2019

Magewell Pro Convert TX HDMI & SDI hardware NDI encoders

At the Magewell booth ...

This was the first public showing of the Pro Convert TX models. These sub-Ä400 "full-NDI" encoders are available in HDMI & SDI versions, encode resolutions up to 1080p60 HD, and retain most of the other features of the Pro Convert Plus models. The most noticeable exception is the  loop-thru output, but the Tally/PTZ control output socket is retained. Available after NAB 2109.


Magewell Pro Convert hardware NDI encoders

Magewell has launched a new range of hardware converters, with HDMI and SDI versions, which generate IP video using NewTek's NDI protocol. They all feature full-spec NDI encoding (not NDI|HX) over gigabit ethernet or USB (via RNDIS), with PoE or USB powering. HDMI loop-thru plus 8-pin output for PTZ (VISCA) control via NDI PTZ, and external tally. 1/4" mounting hole. Web-based GUI for changing settings.

The first model, which we have been testing since before IBC 2018, was the HDMI 4K version, with other models to follow, including SDI and cheaper HD-only versions. You can read more about some our tests on our Facebook pages for ZEN Computer Services and ZEN NDI Software.

The HDMI 4K & HD-only versions are now shipping and typically available from stock, with the SDI 4K expected in Feb 2019, followed by the TX versions. Read more here

Magewell Pro Convert HDMI Plus 4K NDI encoder

Create NDI routing switchers in any size from 6in-2out up to 20in-24out

The ZEN NDI Router has had a makeover during the summer of 2018, which includes the variable size creation facility, Routing Preset switch buttons and full Config file load/save capability for quicker restoration of favourite configurations.

 

BirdDog Studio NDI encoders available from ZEN

On demo and available to buy from ZEN, the BirdDog Studio is a portable NDI converter designed to take an SDI or HDMI input and transmit it using the full-quality NDI protocol over a LAN via gigabit ethernet. As of the 2.25 fimware it can also decode a YUV NDI stream and create SDI/HDMI output. It also acts as an HDMI>SDI or SDI>HDMI converter, and is particularly suitable for converting the output of video cameras into a production-quality IP feed for use with a variety of switchers, including NewTek's Tricaster and other software switchers like vMix, Wirecast, VidBlaster and OBS.
 

Pro Capture HDMI 4K Plus LT (includes Loop Thru output)

A revised version of the 11150 Pro Capture HDMI 4K Plus has been introduced, featuring a Loop Thru HDMI 2.0 output of the incoming HDMI signal. The LT version has p/n 11152, and is available at the same price as the 11150.

Colour Gradient Background generator for NDI

Adding to out existing selection of software utilities which make use of NewTek's NDI protocol for production video over local networks, the NDIGradBG app generates 4-way colour gradients in various styles. Download here.

Magewell USB Capture Plus

Adding to the existing Plug-&-Play USB Capture range (the HDMI & SDI dongles), the new USB Capture Plus video capture devices are available in three different versions.

  • HDMI - with loop through & analogue audio I/O
  • SDI - with loop through & analogue audio I/O
  • DVI - with breakout cable & analogue audio I/O

Like the existing dongles, the new Magewell devices continue to work in Plug-&-Play mode, ensuring simple driver-less operation and compatibility with a wide range of host software applications. However, a software utility allows control over the video settings in a manner similar to the Pro Capture cards.

These products are now shipping, and were officially launched on Magewell's booth at ISE 2017 in Amsterdam, which ran from 7-10th Feb at the RAI.

HDMI & SDI  versions include pass-through ports

ZEN and Magewell at IBC 2016 - Amsterdam RAI  9-13 September

ZEN will be helping Magewell at IBC 2016

Martin was in Amsterdam for the IBC 2016 exhibition and could be found (for much of the time) on Magewell's booth C79 in Hall 5 (that's at the northern end of the complex, to the right as you enter via the main entrances)

The Magewell booth featured the 4K cards along with the rest of the product range of PCIe and USB3 video capture devices.

There was also a demonstration of NDI,  using a Quad input Pro Capture card to ingest multiple HD input signals and transmit them to a second PC via NDI.

(This was almost 2 years before Magewell announced the introduction of their Pro Convert hardware NDI encoders!)

NOTE: The ZEN office in Salford is usually closed for the duration of IBC in September.


Magewell Pro Capture 4K cards

Adding to the existing Pro Capture range, and sharing the same common driver, the new 4K cards are available in four versions.

  • HDMI - up to 4K at up to 30fps
  • AIO - SDI & HDMI at 30 fps
  • HDMI Plus - up to 4K at 60fps
  • AOI Plus - 6G SDI (4Kp30) & HDMI up to 4Kp60

Magewell cards offer different features to Blackmagic, who typically only support broadcast video resolutions and have limited on-board processing, whereas Magewell are aiming at other markets as well, where computer output needs to be captured (at other resolutions - eg 2560x1440) and streaming applications, where one input might need to be recorded and streamed at different resolutions. The Magewell cards can supply multiple different sized streams to different host applications simultaneously, unlike the Blackmagic cards.

Magewell USB3 Video Capture Dongle re-engineered

This versatile pocket-sized USB3 video & audio capture device for Windows (or Mac), available in two versions with either HD-SDI or HDMI input, has been re-engineered into a robust metal case (pictured above-left) with a larger USB3 connecter, replacing the original plastic-cased version (on the right)

It will auto-detect the video resolution and, in the case of the HDMI version, accept a wide range of graphics card output sizes as well as regular broadcast video resolutions, either SD or HD, with stereo audio.

It requires no drivers to be installed, as it emulates a standard webcam and uses the default Microsoft drivers, making it suitable for use with any streaming or capture software designed to allow a webcam for input. Embedded audio is also supported and appears as a standard Windows audio recording device. More from Magewell

Live web streaming support services for small-scale events and webinars

Live web streaming and vision mixing from the desktopZEN Computer Services can offer support for live web streaming for smaller-scale events, product launches, training sessions, and suchlike. The service is aimed at video production companies and videographers with little or no prior experience of web streaming who have been asked to provide such a service as an add-on to existing video coverage.

At its simplest level, ZEN will provide the encoding equipment and operator, and provide quality-control monitoring of the stream during transmission.

The supporting services can be extended to include audio mixing and software vision mixing, allowing multiple cameras to be used, along with caption overlays and vision inserts from virtual VTRs. Whilst not intended as a replacement for a full OB, the system allows many of the same elements to be included in a live web broadcast, operated from a desktop PC, at a relatively modest cost.

Final details and rate card are still being worked on, but please phone or email if this is of interest


A short video about lighting in modern office buildings   

Lighting in modern office buildings

Inspired by the techniques shown at the IOV "Shooting the Perfect Interview" Roadshows back in 2009, in this short video Martin talks about, and demonstrates, the benefits of using lighting when filming in modern office buildings. With modern cameras able to get a well exposed picture in fairly low light, it's easy to forget what a difference lighting can make.

The changing face of Manchester

Those of you who have bought systems from us in the last few years may be familiar with our "Manchester Skyline" Windows wallpaper image (left) taken in January 2003 (from outside our old premises in Salford Quays). There has been a huge increase in residential building in the city since then, including the Beetham Tower, so we thought we'd offer an updated image from Summer 2006 (right).

Looking back at Caption Generation ...   

Aston keyboard detail Back in the days before microprocessors, Character Generators were members of the Graphics Department armed with sheets of Letraset and cardboard. The finished caption cards were then handed over to the stage crew who acted as "Caption Pullers". For a title caption sequence, cards were stacked in shooting order alternately into two separate piles (like A/B film rolls) and placed on blackboard-style easels somewhere in the studio. Two cameras (and cameramen) would be assigned to shooting the captions, with the Vision Mixer switching between them. As soon as the red light went out on the camera, the Caption Puller would pull the top caption off the pile and the cameraman would frame up on the one underneath.

The more complicated captions were made as a multi-layer cardboard sandwich, with holes in the front layer behind which cardboard tabs could be pulled out to reveal additional text or images beneath. Each one had to be individually made by hand and, with a few exceptions like the opening/closing station logo, could rarely be used again. (read more...)

The art of better sound - when to say "No"  (article on the support page)

For some people, their experience of recording sound starts with making wedding videos or recording other live events. As a sound recordist, youíre there to capture whatever is happening, as best you can. Getting better sound under those conditions usually involves better equipment, or making better use of what youíve already got. But not all shoots are like that, and itís easy to fall into the trap of thinking thatís the only way of working. What Iím saying is that whenever you can have any control over your environment, you should try to make use of it.

Directors and cameramen donít make things easy. Sound is rarely seen as being as important as the pictures, and the soundman is well down the production hierarchy, so you have to learn to be assertive (but tactful). With few exceptions, no-one else on location actually listens to sound objectively. The human brain is remarkably good at rejecting unwanted noise when it suits us, and locations are usually chosen on the basis of how they look, not how they sound. Camera lenses offer 100% rejection of anything out of shot, but microphones don't, no matter how directional you think they are. So donít just accept shooting in a noisy location without exploring the alternatives. Continued - read more...

Here at ZEN we have successfully used AVG Anti Virus for many years on our PCs, and can definitely recommend it!

AVG Professional Single Edition

What we're about . . .      ZEN is not a traditional Audio-Visual dealer who started selling computers, nor is it a computer shop that also sells video products. You won't get any salesmen giving you the "hard-sell" when you call, just straightforward advice and information - which for some callers is the knowledge that they don't need to buy whatever it is they thought they needed! Above all you'll be dealing with someone with a wide range of experience and knowledge of both PCs and video production. We're not the biggest, nor necessarily the cheapest, but we are one of the longest established computer/video specialists in the UK.

Company history . . .      ZEN was started in the 1980s by Martin Kay, then working for ITV at Granada's Manchester studios, who built his first 6502-based computer in 1979 from an Ohio Scientific kit, bought in the USA whilst working as a Sound Recordist on a film shoot for World In Action. With the advent of the Amiga, which could be gen-locked to a video source, Martin started writing a variety of video-related software. This included subtitling & tele-prompting, ident clocks, scoring software for sports & gameshows, and specialist software to mimic other computer displays for use in TV film dramas like Cracker, Prime Suspect and A Touch of Frost. Martin left Granada in 1993 to concentrate on his computer-video activities with ZEN, following a natural path into non-linear editing systems, for many years the main business activity, although he still maintains an active interest in video production.
