Manage and Monitor

Issue 93 - September 2014 In less than a month’s time, British television producers will be asked to deliver their programmes to broadcasters as files rather than tape. Some have been doing it for years. For others, it’s a whole new world. Fundamentally, the change is just replacing physical items like tapes, labels and VT reports with their zeros...

An editors perspective

by Larry Jordan Issue 92 - August 2014 When it comes to chroma-key (also called “green-screen key”) the phrase “Don’t worry, we’ll fix it in post.” is a recipe for disaster, because if you don’t shot your key right during production, it will be painful, timeconsuming and expensive to fix it later during editing. I know, because I’m an editor. Bad c...

When the going gets tough

by Will Strauss Issue 88 - April 2014 When working in the field, the kit we use has to withstand a fair old battering. And Im not just talking about the cameras, viewfinders and those expensive lenses. While glass still needs protecting, these days so does your laptop, your storage, your memory cards: the lot. They all need bags, cases and toughene...

Why test and measurement is for real life, not just for e...

by Will StraussIssue 79 - July 2013 Thanks to its long-standing association with virtually incomprehensible acronyms, dark machine rooms and (lets face it) engineers with unruly beards, the subject of Test and Measurement (T&M) always gets a bit of bum rap. Yet, for all the pre-conceptions, it is a hugely important part of the production and broadc...

Audio phase: Robin Palmer asks why it is wobbly?

Phase meters and audio vectorscopes are to be found on most test kit involved with audio monitoring. This is important because left/right audio correlation problems between the channels will distort the stereo ‘image’ and could degrade mono compatibility. If left and right phase should ever be inverted, any centered identical audio would be cancell...

Life live beyond the Premier League

by Kieron SethIn Europe outside broadcast has traditionally been within the reach of a handful of deep-pocketed television companies. Across the Atlantic, small OB vans have been popular for years with niche, regional news crews beaming state pie eating competitions to eager viewers. With the advent of Local TV and low-cost fast turnaround producti...

What you see is what you get? Doubtful!

by Robin PalmerThe colour you see is not necessarily the same colour experienced by someone else looking at the same thing. It all depends on the viewer and the viewing conditions as well as the actual colour of the thing. In some professions having perfect colour vision is a matter of safety as in the case of airline pilots and those in railway si...

Technical Testing Joins Forces with Visual Monitoring

In the past, test and measurement equipment was designed exclusively for broadcast engineers. Vectorscope and waveform read-outs sketching out shapes on a scope were readily understood by technicians fluent in the language of signal analysis. Today multi-camera digital acquisition is not merely the domain of the broadcaster; television production i...

Wibbly Wobbly Waveforms

The very first analytical electronic instrument, developed in the late 1890s, was the oscilloscope. This used a cathode ray tube (CRT) to paint a graph of voltage on the Y axis versus time on the X axis. Once television became a practical reality in the 1930s, the same instrument was applied to the video output from the camera and became the very u...

Pointing out the right colours

In the old days of PAL and NTSC analogue television, a vectorscope was an essential tool for examining chroma at every part for the programme production and transmission chain. This was because the colour information was carried as a phase and amplitude modulation which could be sensitive to a variety of transmission or recording non-linearities an...

Testing times of a 4K world

The term '4K' applies to some five slightly different picture formats with around 4,000 pixel horizontal resolution: all much bigger than HD. In fact roughly four times the total pixels required for 1920 x 1080 pixel high definition. 4K has been around for some years but was until recently only affordable by producers with mega budgets. Advances in...

Handheld T and M the broadcast emergency service

“Test and Measurement”. Shudder. Like “Health and Safety”, “Bus” and “Replacement Service” or “Keith and Orville” it’s a collocation of words that fills me with dread. Seriously, who wants to read about “Test and Measurement”? Well, as it turns out, the answer is: quite a lot of people. Because, despite its lack of glamour, it is hugely important....

Gamut errors: Who cares?

Gamut errors are the most common video signal problems. This is because colour television or cinematography depends on being able to represent every pixel on the screen in terms of red, green and blue. We want to deliver perfect RGB signals representing all the possible colours in our pictures. Virtually all display technologies use RGB primary col...
