WORDS ADAM DUCKWORTH
A nyone with a smartphone can livestream via Vimeo, Periscope, YouTube and Facebook Live these days. Many clients experiment with a social media intern waving an iPhone around for a Facebook Live broadcast. But most realise that this doesn’t represent a brand in a professional manner – and instead search for quality live streaming. If you have cameras and Wi-Fi or a reliable 4G connection, then it’s possible to stream right now from a desktop or laptop, with not a huge amount of extra cost. It’s not quite as simple as plugging camera into laptop and setting off, as the camera will output a high-resolution signal. Streaming requires a low-data-rate 720p HD. So, you will need an internet broadcasting device/encoder – or
a more basic HDMI capture card – to turn your camera signal into something a computer can use to stream from. Blackmagic offers the £654/$695 Web Presenter 4K, which takes input fromHDMI or SDI cameras. This has a simple, single live camera input and a second input, like a slide show or pre-prepared video on a computer linked via HDMI. Then, switch between them – complete with built-in dissolves. For a professional production, though, you should run multiple cameras – and there are many TV broadcast units built for this that end up being pretty expensive. For more affordable options that let you switch between multiple cameras, Blackmagic has you covered with a whole selection of products. Blackmagic’s Atem range is a popular choice, and the
SIMPLE STREAM Blackmagic’s Web Presenter (above) is a very easy way to go live with your pro camera, while the Atomos system (left) plugs into a Ninja V and turns it into a multicam broadcast studio
