Product Notes & News
![]()
I've been a regular contributor to user groups and technical forums for
the last 20 years or so, and have written hundreds of posts
on a whole range of computer, audio & video
production topics. Trouble is, I never kept copies of any of them, which
is why I've now created a web page for some of them. Let me start by saying that I've not exactly been "wowed" by the whole 3D bandwagon, but I am warming to it... Read More |

Live web streaming support services for small-scale events and webinars
At its simplest level, ZEN will provide the encoding equipment and operator, set up a web-page with customer-branded player and optional live chat window, and provide quality-control monitoring of the stream during transmission. Streaming costs can be calculated on a Pay-as-you-Go model based on the number of viewer-hours used, which is ideal for smaller audiences, as there is no minimum charge. The player can be password-protected to restrict the viewing numbers to an invited audience, further helping to keep costs under control. 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 |
Panasonic AG-AF101 test shoot - interview footageOn 10th Dec '10, Martin was invited to an open day at Holdan, who are distributors for the AF101, the PAL-world version of the AF100. It afforded a chance to see this new camera and perform some hands-on tests. Martin took the opportunity to shoot an interview with Richard Payne of Holdan talking about what Panasonic have given us with the AG-AF101, the new micro four-thirds video camera which records to AVCHD files from a single, large format sensor. The lens used was a Zeiss Distagon Compact Prime 35mm T2, with lighting from an LED panel for the key, plus tungsten fill, back and background lighting. Sound was from a 416 short gun mic on a stand, plugged directly into the camera. |

| Martin's
comments:- In use, the camera is not unlike Panasonic's other handi-cams (the 151 & 171) in many ways, but without the need to switch all the lens functions into manual mode, should that be the way you like to work. Since this was shot at an open day, in a relatively small space with other people present, there was not time for me to fully explore every feature and option that the camera has to offer, but I did want to take some footage away with me that was a little more meaningful than just pointing the camera at whatever was around me, lit only by the standard fluorescent house lighting. I hope this video gives some flavour as to the image quality of which this camera is capable when combined with quality lenses. |

Part of the team at the IOV VideoSkills RoadshowsThis year Martin has been one of the trainers at the
IOV Videoskills Roadshows,
aimed at helping videographers improve their basic
skills. In the course of the day the topics covered include lighting, sound, camerawork and
editing, with a two-handed interview as the sample subject matter. This is the
resulting video from the Naas event. |

Matrox MXO family -
The new range of MXO I/O boxes are designed to work with Final Cut on the
Mac (both Macbooks and MacPro), Premiere CS4/5 on the PC, and in the case of the Mini will also
soon support Avid Media Composer v5. In all cases they serve as a portable breakout box with high quality analogue and digital video outputs. The MXO2 includes inputs as well as outputs and the range includes the following connection options:-
Matrox MAX - The MAX hardware is a faster-than-realtime H264 MPEG4 video encoder which is available as a PCI-Ex card (called CompressHD), or as a factory-fitted option to the MXO2 I/O boxes. See Matrox page. |

Martin's mini-review of the Panasonic HMC 151 camera- recording in AVCHD format on SDHC cards
I'm not a fan of compact cameras generally - I'd rather have something with a traditional manual lens on it - so I always miss having clearly marked focus and iris rings, but at least the HMC 151 has a "normal" zoom ring on which the servo can be disabled. What I couldn't fail to be impressed by was the overall picture quality when viewed as HD. I'd been monitoring the down-converted SD during much of my shooting, which looked OK but nothing special, so it was only when I finally viewed the AVCHD files via the Panasonic Viewer software that I saw the full amount of detail recorded. And it's this high picture quality, for the price, combined with the low running costs of SDHC cards, which make this camera appealing for a wide variety of applications. Current price (as of Apr '09) is 3395.00 inc 2x16GB cards & reader. |

Lighting in modern office buildingsInspired by the techniques shown at the IOV Videoskills Roadshows, 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. |
Premiere CS4.2 Notes - Matrox v4.2 drivers released Jan '10Windows 7 is now with us, along with Premiere Pro CS4.2, and as usual this requires a new driver from Matrox to support their cards. The good news is that Matrox have now released new 4.2 drivers via their web site. These drivers are designed to work with Adobe's recently released 4.2 & 4.21 updates to Premiere Pro CS4, which you should not install until you can install the Matrox 4.2 drivers at the same time. This driver release also makes it possible to run the Matrox Compress HD hardware H264 accelerator alongside the RT.X2 in the same machine. If you are running Adobe Premiere Pro CS4, you
are probably already aware that Adobe's 4.1.0 update introduced
major issues with Axio and RT.X2 systems unless you also upgraded the
Matrox drivers to the matching 4.1 version, which you must download from
Matrox. Because Adobe have an automatic updater to download and install their
updates, there's a danger that you might update Premiere without realising the
consequences, and subsequently think your system has developed a fault due to
the driver mis-match. |
Looking back at Caption Generation ...
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, you’re 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 you’ve already got. But not all shoots are like that, and it’s easy to fall into the trap of thinking that’s the only way of working. What I’m saying is that whenever you can have any control over your environment, you should try to make use of it.
Broadcast
workflow on a DV budget
Once again we have been working on My North West for Granada TV, and the second series is now complete (weekly transmission started 7.30pm Thursday 23rd Aug 2007). This time there were 8 episodes, and we were involved with the location sound as well as online-editing/grading/dubbing. Unlike last year, the edit software this time was Avid Xpress Pro, and transfers to DigiBeta were via the SDI Mojo. All episodes passed Tech Review first time, except for one which was hit by the little-publicised Avid "green lines" codec bug in v5.2. So now we are better equipped than ever to offer our services and support to anyone undertaking independent production for broadcast.

plus a 1.28GB GTX570 graphics card (which fills 3 backplane slots) and a 750W
PSU. The whole unit is surprising compact (and quiet), in an Antec 300 case (as
in the RTX2 system pic below) measuring 458 x 465 x 205 mm HxDxW. There's 7
usable disk bays, of which four are occupied, plus there's two eSATA ports &
USB3 for external disk connections. O/S is Windows 7 Pro 64 bit.

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




ZEN Computer Services are launching a new back-end service to support 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.






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. 
Running under Windows XP, it is
designed to work with AVI video files, and is not tied to any particular
video capture hardware or editing programme. We have a demo system
operating at our Manchester base.
