There are digital stills cameras, from amateur to professional grade, which now also function as video cameras and at the high end, specialist video cameras with which you could even shoot a feature film. There are smartphones and tablets bodycams worn by police, cyclists and daredevil skateboarders dashcams and baby monitors cameras for home security or watching wildlife cameras on drones. Within minutes, I had listed well over a dozen. In preparation for this article, I compiled a list of devices that now ‘do video’. What was once an exotic technology found only in space satellites is now in everybody’s smartphone! This revolution is boosted by ever more powerful video-signal processing chips, and the capacity and speed of solid-state memory, such as the near-ubiquitous SD memory card. Since then, they have been attaining higher resolutions, better sensitivity to lower light levels, and have become cheap. Sensor chips for image capture came to consumer digital cameras and camcorders about 25 years ago. It used to be said that quality expectations of video production have been driven high by television and movies, something we’s be hard put to match but in the era of YouTube and Facebook amateur video, maybe that is less true? A technical revolution: video everywhere I’ve filmed at graphic design conferences, where slides and other images were an essential to understanding the subject, and audio-only would be quite mystifying.Īnecdotally, video is said to appeal better to a younger audience than audio alone. However, it’s not my job to put you off! Visual content can be very informative. It’s cheaper, easier, and in the edit it’s so easy to improve a presentation by snipping out the ‘Ums’ and ‘Ers’… and you can’t do that as seamlessly in a video edit. If video from an event will be no more than a speaker’s ‘talking head’ and some Powerpoint slides, I tend to suggest concentrating on a good quality audio recording. Storing digital video can consume huge amounts of memory, and costs bandwidth to transmit with both image and sound to kick into shape, the editing process is more complicated and video technology and technical standards have been changing very fast. Good video kit is expensive, and often difficult to transport. In fact, I often urge caution, because making good video takes more skill and time and planning than audio. So, you might expect me to be an enthusiast for video technology. I participated in two working groups of the British Computer Society, looking at how BCS branches and groups might video meetings, primarily for the benefit of those who can’t attend events in person. I don’t consider myself a video professional, but I’ve made a several budget educational videos, and recorded meetings and conferences. This is a follow on to our previous guide exploring ways in which audio recording may help with parliamentary work, and explaining how to do it on a modest budget.
