Calibrating monitors for HLG-1.2 High Dynamic Range working

We’ve now done a couple of Sony BVM-X300 (4k/HDR OLED panel) monitors for HDR-TV deliverables to the BBC. The Beeb are behind the Hybrid Log Gamma standard, currently at 1.2 for broadcast. It’s benefits over Dolby’s 10-bit version of their Vision HDR system (also called DolbyPQ) are many and rather splendidly the DVB as well [...]

BM UHD/4k converters – some gotchas

https://www.blackmagicdesign.com/products/miniconverters/techspecs/W-CONM-17 I've used a few of these guys recently - Blackmagic's quad HD/SDi input to HDMI 2.0 output for taking the UHD / 4k (either tile or 2SI standard) and making something that will display on a 4k domestic TV. They seem to work quite well, but here are a few things that I had [...]

So what should you do about Quicktime on windows?

Earlier this week a story broke from Trend Micro  (echoed by America’s department of homeland security) about a current security risk in Quicktime,  advising that due to compromises, users uninstall the product from their machines as soon as possible. A lot of doubt and uncertainty has been sown around this announcement, lets take a look [...]

A review of Colour Reproduction in Electronic Imaging Systems: Photography, Television, Cinematography by Michael S. Tooms

All of my colourimetry comes from doing it; my theoretical knowledge isn't that great as I didn't study it at university and the colour training at the Beeb, although entirely appropriate to what a TV engineer needs was just that; TV-centric. Over the last ten years I would credit the following industry colleagues for widening [...]

Shooting and editing HDR via Avid using CLog gamma

We've got BVE2016 coming up and one of the things root6 will be showing is an HDR workflow via Media Composer using Canon monitors. HDR is still a bit of a crap-shoot as far as standardisation is concerned with the BBC/NHK system, Dolby Vision, Sony's SLog3 and Canon's camera-native CLog. The principle of using an [...]

Audio over cat6a cable?

My podcast-partner in crime, the mighty Hugh Waters asked me how often I run audio signals over twisted-pair data cable in media facility builds. Has has a customer who is eager to do it this way. I’ve done it a few times and it’s fine with a few considerations. Earthing is still important and since [...]

Barnfind integration with third party control panels

Barnfind are one of the products I'm responsible for at Root6 and I love them for their forward looking attitude and the fact they embrace open standards; if you see an SFP hole or a BNC connector you know that it will work with any other manufacturers (unlike Evertz who re-define the standard and put [...]

Gotchas with updating firmware over RS232

I've recently been upgrading Boland BVB25 OLED monitors over their RS232 serial ports; aside from needing a USB/serial adaptor (I use the Keyspan which mimics an old PC serial UART) you also need a null-modem cable (i.e. where Tx and Rx are swapped over). You can tell if a null-modem cable is required by the [...]

Typical edit suite monitor calibration; some traps for young players

I spent the morning in a very typical Soho edit room with a JVC DT-V24-series LED-backlit LCD as the "front of house" monitor and an LG LED-backlit LCD as the client display. It's quite easy to get the JVC looking right - BBC style 6504k for Rec.709; I've waffled on about this a lot in [...]

Media Composer 8.4, Interplay, custom rasters and a lot more

Over the last 12 months or so a number of Avid houses and smaller boutiques have moved their workflows onto the Avid Interplay environment. Although there are additional setup stages and more time involved in the client installation, this initial effort is more than rewarded by the subsequent benefits that working within the Interplay environment [...]

Backup versus archive

Knowing the difference and understanding what to do about it Although the transition from analogue to digital has been going on for nearly twenty five years, many users are still unclear as to what the difference is between the concept of a backup and an archive. In a nutshell, a backup relates to current information in use that is [...]

Storage Explained

Local Storage/Direct Attached Storage Typically this is defined as storage with no ability to provide any real-time sharing capability. Most common is the FireWire,  USB 3.0 or ThunderBolt drive, used for moving media from a shoot for example, but local storage is also used when bandwidth demands become too costly an option for shared online storage. Shared storage can be [...]

Earth Leakage – in water!

I recently bought an Agilent U1191A clamp-meter. This is a piece of test equipment that can measure current flowing in a conductor without having to break the circuit (how you would if all you had was a digital multimeter). The jaws physically couple around the conductor in question and by induction you can measure the [...]

Why do manufactuers over-specify power requirements for broadcast equipment?

It's actually a rhetorical question and I'm glad they do. Most of the time I have to tell a customers' electrician and air-con contractor how much power (and hence how much heat) the machine room will be pulling/genarating. Most customers refuse to believe that 99.9% of the electrical power entering a server room/TV MCR leaves [...]

What’s the best setting for Gamma with Rec.709 video?

 I've been calibrating TV displays for around twenty-five years and have always leaned on the BBC practice of setting peak white at 80Cd/m2 and the white point at 6504k. For all the decades of standard definition work a gamma of 2.2 has been used. This is required because television cameras don't have a linear transfer [...]

Perceptual video quality and compression – PSNR measurements

Compression is a fact of life, there have only been two production VTRs that stored uncompressed video – D1 and D5; they are no longer used because they were both SD (and D1 was only eight-bit video). So, the vast majority of the material we handle is compressed and so there should be a way [...]

Measuring fibre cabling and the problem of encircled flux loss

  Last week I went on a very interesting training day courtesy of Nexans – data cable & parts supplier. I went looking forward to learning all about the new standards surrounding catagory-8 cabling for 40 and 56 Gigabit ethernet (a massive 1600Mhz of bandwidth down a twisted pair cable!) and the new GG45 connector; [...]

Blackmagic VideoHub software and QLogic fibre cards under MS Windows in SANs

Here's something from the dim recesses of my brain that I'd just remembered. Blackmagic VideoHub routers take all their network traffic over port 9990; which is also used in some QLogic/SAN configurations for metadata traffic. They don't play nice with each other. To fix this set the BM Software (whilst USB-connected to the hub) to [...]

Amulet – they fixed OS-X's Temporal Dithering issue

As mentioned in a previous post temporal dithering on OS-X has proved troublesome with Amulet (and in fact it bedevils all KVM-over-IP systems). The guys at Amulet have written a Kernel Extension that stops the card turning on temporal dithering. James, their engineer, explained to me that it's a different technique between nVidia and Radeon, [...]
