  1. The HD video function of DSLRs such as the Canon 7D has sparked a renewed interest in low budget film and video making. This has led to an explosion of lower-budget video cameras being produced using similar technology. So if you've started in still photography or basic DSLR video shooting, what do you need to know when progressing on to cameras (such as our inhouse cameras, the Sony FS100) which have been designed specifically for video capture? This article will cover the various differences between the mediums and allow you to make the hop up to broadcast quality video.

    Gain vs ISO

    img_3329

    Gain and ISO are essentially different scales for the same thing (think fahrenheit vs centigrade).

    ISO (also known as ASA) was used with photographic film to donate the speed of negative photographic materials. With DSLRs the ISO is an equivalent that refers to how sensitive the sensor is to the amount of light. A higher ISO means more sensitivity therefore you can see more with less light.

    Gain is the same thing, an electronic amplification of the video signal, and was incorporated into camcorders before stills cameras became digital. Voltage is added to your sensor and is measured in decibels (dB).

    The important thing to note, whether you're calling it ISO or Gain is that their use introduces noise into your video, which is especially problematic when doing a lot of post production work, including grading.

    White Balance

    Purpose built video cameras often have more variable white balance, and often black balance, settings. As well as auto functions, you can manually set the white balance by shooting at a white subject (as with most DSLRs), but you can also dial in what Kelvin setting you want, which is great if say you want the image a bit warmer (though make sure your monitor is set correctly if judging by eye).

    Shutter Speed

    By setting a video camera to a "normal" shutter speed of 1/60th second (the time it takes to scan one video field in the NTSC standard), the electronic sampling is done at the maximum time allowed by the field rate of the TV system. This represents the maximum exposure possible with normal sampling. Changing the shutter speed when shooting video is useful in a number of situations. When filming computer screens or under certain lights you can adjust the shutter speed to reduce any flickering that may occur. When recording time-lapse you may also want to reduce the shutter speed to add some motion blur. When shooting slow motion you may want to increase the shutter speed to get sharper images (reduced motion blur).

    XLR inputs

    img_3332

    Simply put camcorders have much greater functionality when recording sound. Most DSLRs still require an add-on to enable you to control the audio levels being recorded by the camera. Camcorders generally come with two XLR inputs as well as an onboard mic. As well as controlling the levels these inputs are normally switchable between 'Line;, 'Mic', and Mic +48v. You will also be able to control which mic input gets recorded to which of the two audio channels as well as being able to monitor each channel individually or as a 'mix'

    Zebra

    Basically this shows (with a striped 'zebra' pattern') areas of the picture that are overexposed. There are two types of Zebra, 100 IRE or adjustable 70-90 IRE. With 70-90 IRE the Zebra pattern appears on highlights between 70 and 90 IRE, depending on how you set up the camcorder. IRE was labelled as such by the Institute of Radio Engineers and represents the composite video signal in terms of a percentage. 70-90 IRE is generally of use when filming interviews as you'd look to get some zebra patterning on the cheeks, forehead and nose.

    With 100 IRE the zebra pattern shows any areas of the image that exceed 100 IRE which is the limit of legal (broadcast) video. Therefore when using this you adjust your exposure until the zebra patterning just disappears. These days many video cameras come with built in wave form monitors which can help with managing highlights.

    Peaking

    Peaking is a monitor function that shows you the areas of your video that have the greatest sharpness. This aids focusing and with the increased use of dramatic shallow depth of field shots is a vital tool to using these large sensor cameras.

    Area Safe modes or 'Guides'

    Nowadays it’s easy to film in any aspect ratio, upload it to YouTube and job done - people will be able to watch your video. But what if you're progressing to filming commercials or programmes fit for TV broadcast. Commercials are still not yet broadcast in this country in 16:9 aspect ratio, although this is the normal for anyone shooting almost anything these days. This is where the Area safe mode on your camcorder monitor becomes vital. It'll put lines on the monitor that aren't recorded or 'burned in' to the video that show which of the image is in 4:3, or 16:9. There are also often options as to the ratio of guide lines you want to use if any giving you control over your shooting requirements.

    Detail of image with bottom half with 30db gain, you see more detail in the shadows but you get more grain or artefacts which become a problem if doing a lot of post production work such as grading.

    To conclude, DLSRs have done wonders over the last few years for video capture, however there are limitations which can be overcome by switching to modern quality camcorders for video. This article has covered a few elements which will hopefully facilitate the change!

     

  2. We've just returned from a challanging shoot (to say the least) up in Wigan and Selby, Yorkshire shooting a TV ad for Canopies UK. Here are some shots of the shoot, which included a rain machine, cast of 12, multiple locations and a naughty malfunctioning FS100 camera!

    Lots of people I know aren't on Twitter. They see no reason to be. They see it as just another fad and they're already on Facebook and its not something that they find they're 'expected' to do for work. They also tell me that they've not much to say, even in 140 characters.

    I used to agree. To anyone not on Twitter I say this: You can use it how you like. You don't have to be trying to market something or to be 'networking', or even to care about celebrity gossip. I use it as a fantastic resource. I use it for news and information. To my friends who are unfamiliar with Twitter (and my mum) I describe it thus:

    Twitter is like walking in to your local WH Smith, going to each Magazine and News section that interests you and reading the headlines. For free. And if you really want to, if something puzzles or concerns you, you can turn round and ask the Author or Journalist about it. Or you can pick the paper up and wave the headline in the direction of your friend across the street.

    Twitter can get more interactive as you use it. It can as a by product lead to 'social networking' as you interact with other people and businesses. However, I use it primarily as a resource for many facets of my life.

    I recently Tweeted a technical question regarding the Sony FS-100 camera that we use for corporate video productions and got a professional and helpful response from a colleague in America:

    Frank Glencairn ‏@FrankGlencairn

    @butchershookev Ninja2 or Samurai with an Atomos "Connect" - hands down best bang for the buck IMHO.

    That narrows down my search for a suitable technical tool, thanks Frank (who I've never met).

    The other day I read through the 'headlines', as I regard Tweets, and it meant I wasn't late for a meeting because I read this:

     BrightonHoveCouncil ‏@BrightonHoveCC

    St James's Street currently closed for utility works due to reopen Thursday 18 October bus diversions are in place http://ow.ly/eu4bM 

     So, I caught an earlier bus and my virtual activities led to a productive real life exchange.

    As well as business related Tweeters , such as Frank I also follow local information services like the council and other local services. I also follow newspapers, and the odd person who is entertaining because its not all serious, but doesn't have to be all X-factor gossip either.

    My favourite ever Tweet was from the QI team, or 'Elves' as they call themselves:

    The QI Elves ‏@qikipedia

    LEGO is the world's largest tyre manufacturer - they make 318 million tyres each year

    This fascinated my children.

    So for all you Twitter dismissive out there, realise that you can get out of it what you want, and a whole lot more. The most important thing is to be selective as to who you follow. I never follow people just because they follow me, I don't regard this as impolite, after all I've never expected @stephenfry to follow me back. I choose to follow people that I can learn from or who are interesting.

    I bought the weekend paper for the first time in about two years last week. It cost £2.10. It didn't tell me anything about my special areas of interest. It didn't tell me if a certain road in Brighton had closed in the last ten minutes. It didn't tell me any news that I wasn't already aware of. I did the crossword. I did enjoy the feel of the paper.

     Twitter is free. It has links to videos. Just saying.

    You could follow me @butchershookev but you should be warned I am more of a good listener.

    We didn't know when we were up shooting our Olympic video with Aecom recently, but we had a world exclusive of the Rio 2016 Olympic Park - 2 months before it is being shown off the newspapers!

    We met with various important Aecom big wigs, including the Olympic statium designer himself - you can see our video production for them here.

    You can read more about the Sun's "exclusive" here.  ;)

    *We're not 100% it was a world exlcusive - but it's jolly well beaten all the papers!

    Vzaar is a fantastically versatile video platform which we use to host all of our corporate video productions. We were delighted to be the first video production company to be interviewed and featured in a case study on Vzaar's website.

    Vzaar is considered to be the best, most flexible platform available for companies to host video - a sign of how well regarded they are is the fact that Oliver Stone is a major investor.

    You can see the case study here.
