The relentless squeezing of production budgets means that we are all keen to make the most of the money that we have and this article aims to offer some sensible advice.
Firstly, some good news - Broadcast equipment is getting cheaper, so the questions always asked by Production Companies are the following, which we will attempt to answer:
• How to compare rental prices from competing rental companies?
• What equipment to use?
• Whether to buy or hire?
• Or, if buying is considered, then when is the right time to buy?
Alexa Mini or Amira?
(or why I must have a Mini because it’s newer and better isn’t it?…no wait….)
This is a short article to highlight the differences and similarities between the two cameras in order to assist VMI clients in making sensible and informed choices about which system would be most suitable for a given project.
This is a short article examining the most popular lighting fixtures and technologies concentrating on their advantages, limitations and applications. As with all such equipment the pace of change and development can sometimes disaffect the end user who will understandably stick to known and trusted tools rather than seeking out new fixtures and technology which are now available.
This article is split into 3 sections:
Section 1: Lighting Technology defines the 4 main categories of lighting technology (Tungsten, HMI, Fluorescent and& LED).
Section 2: Fixtures and Fittings then explore the differences between hard lighting vs. soft lighting; open face lamps vs fresnelFresnel lamps; Soft lights and beauty lights and accesoriesaccessories
Section 3: Common Lighting Setup Examples introduces some common interview lighting setups.
This guide has been written as an overview of HDR technology for TV as it stands in January 2016.

This technology is very new and it still in development so take this guide as a snapshot of the current developments. All major industry players are now on board and the standard has been established but we expect to see few more changes in the final stages of development of this exciting new technology.
Sony have a habit of changing camera models every year and now we have the Sony PMW-F5 and FS-7 cameras, both of which are capable of high quality 4K recording and have the ability to be partnered with £50,000 or £500 lenses, so is the newer FS-7 better than the older and more expensive PMW-F5?
This is a short article to explore the merits of both cameras for modern production.

This is definitely the time of the Gimbal. Ever since the incredibly stable images produced from the first MōVI 10 system went viral in 2013 from an operator doing his best to unseat the camera, the word Gimbal has entered into the vernacular of the filmmaker. Steadicams had been around for a long time but you had to have a trained operator – so if you couldn’t afford a Steadicam, then it was clear that you needed to hire a Gimbal. (You still need training to use and balance a Gimbal effectively but they are much quicker to master).
This article explains the benefits and limitations of using these Gimbal systems and provides essential information if you want to use one in production.

Sony have been very busy with the release of their new version 3.0 firmware release for the F5, and F55, which brings a host of new features and new functionality for these increasingly versatile cameras.
With close to 30 new features, this is a major release and increases both the marketability and perception of the Sony digital motion picture cameras for PMW-F5, F55 and AXS-R external recorders.

What is the collective term for tripod tubes? We think that it is a pyramid! VMI has invested in a new range of rigid tripod tubes to replace the soft bags which house our Sachtler Video 18 and Video 20 tripod fleet. They are very lightweight, yet include wheels for easy transportation and are also aeroplane friendly too but offer much greater protection and look smart too!

The ARRI arrived in the 2nd part of 2014. Smaller, lighter, shorter and less expensive than the ARRI Alexa but most unmistakably an ARRI nonetheless - only with Canon EF and B4 Broadcast lens compatibility, enter the ARRI AMIRA.. This is a brief introduction to the camera and its functionality.
VMI have recently and uniquely removed the coatings from a set of Zeiss distagon lenses in order to bring this very popular ‘vintage’ look into an affordable pricing sphere.
We believe that this may be the first set in the world to have been uncoated and as you can see from the examples, the effect can be as dramatic or subtle as required.
This article seeks to explore the effects that removing the lens coatings can have on an image
ARRI recently announced the introduction of a new Alexa camera series, the ‘XT’ which has a different on board recording module compared to the other established cameras in the series and will replace this range. As the Alexa range is now effectively a ‘fleet’, we at VMI feel at this stage a short précis of each camera’s parameters and functionality is appropriate in order to enable producers and production companies to target the correct package at an early stage of preparation.

VMI are always following trends in technologies of TV production techniques and the field of lighting hire is no exception.
Conventional inefficient lighting technologies use large quantities of power which are beyond the conventional 13A ring mains, so generators, bigger trucks and specialised sparks, etc are required with the inevitable effect on budget and new generation LED lights and cool lights reduce the physical size and also power requirements.
VMI recognise that it you can plus all lights into 13A plugs, then this will have a dramatic effect on cost, by doing without a generator and really big truck! The BBC has already thought about this and this white paper is brought to you here for your convenience.
The Apple ProRes format comes in five versions: Apple ProRes 4444, Apple ProRes 422 (HQ), Apple ProRes 422, Apple ProRes 422 (LT), and Apple ProRes 422 (Proxy). This is an overview of their specifications
There is such a selection of large screen cameras now, all promising to achieve the elusive ‘film look’, that it can be hard for film makers to make an informed choice in the selection of choosing the right combination of camera and lenses.
This short article aims to illustrate the main differences between the current range of cameras in order to help you make that choice!

ACQUISITION: THE EMULATION OF THE PHYSICAL AND CREATIVE CHARACTERISTICS OF 35MM FILM IN THE DIGITAL DOMAIN.
Usually at VMI, we make articles really easy for people to read but the inclusion of this essay this makes no apology for being a Master's level exploration about the aesthetic merit of film vs digital cinema!

This article describes how modern DSLR Cameras are now a practical consideration for shooting productions with excellent results on a low budget.
A shallow Depth of Field can reduce the bandwidth requirement of video, which is good for the internet.
We wanted to test this theory and this article explores this idea and concludes that you can save around 10% bandwidth by shooting with a large sensor camera compared with a small sensor camera, as the shallow depth of field means that you capture only the bits that you want in fine detail and as background is defocused.
All modern cameras shoot on removeable media these days and you need to be prepared to adopt best practise for acquisition, data workflow and post production to get the most of your programme, whilst maintaining media security.

FAQ from clients about using P2:
I have to say, that on shoots where we don't have a data wrangler (all of them), I've found working with XDCAM discs infinitely better than p2 cards. Offloading several 100mbs p2 cards at the end of the shoot has added sometimes 3hrs to the day. We need to find a better workflow!
I understand this BUT it is different now. This is because P2 is traditionally 100Mb/second but shooting on AVC Intra 50Mb/s is the same data size as XDCAM HD ((50Mb/second), so the data is the same size.
Modern transfer tools such as Nexto DI http://vmi.tv/equipment/8/accessories/512/nexto-di-nvs-2525-standard-video-storage-pro-hard-diskarchive-unit , work at eSATA speeds and take all of the pain out of the transfer.
You won't suffer any of the problems of close focus of the XF-305 and you won't need an external recorder either.
The BBC's passing of the HPX-250 will make an easier camera available and the new data workflow makes it practical too!
