So I’ve been working with video production for a while now, but there are still terms I’m unfamiliar with. I’ll often find myself nodding intently with absolutely no clue what ‘aspect ratio’ actually means and then rapidly Googling the second no one is looking. This just won’t do, I need to know what these terms mean – and more importantly I need to know what terms I should understand so that I can learn them. For those of you who are in the same position as I am, never fear. In this week’s blog I’m going to pop in a few of these terms with some very simple explanations to go with them, soon we shall saunter into the office and proudly proclaim ‘Ah! You sir! Do you know what asperity noise is? Hm? I do, HA!’. Just like that. For the record, asperity noise is basically the funny hissing noise that’s caused by defects while recording, primarily, on tape. Posh words for silly things.
To start with, as much as finding a technique to supply these terms through a bite sized media, this video blog from East Anglia video production company, Lambda Films, manages to sum up a couple very nicely.
Easy enough, right? As said in the video, basically aspect ratio how broad the screen is to how high the display is. Here’s a little diagram demonstrating what these ratios are usually designed for. Whack that one into your information bank.
The other well-known term that the video refers to is frame rate. Frame rate, or frame frequency, is generally the number of unique pictures, or frames, there are actually per second. The norm for most motion pictures is twenty-four frames per second (fps), nevertheless more recently in the film industry filmmakers are trialling 48fps. Peter Jackson’s The Hobbit: An unexpected journey was the first film to actually be released filmed in 48fps. Jackson thought to shoot The Hobbit with the non-standard frame rate with the belief that the audience might be more immersed into the movie, as well as to help reduce the motion blur during action sequences. The HFR experienced mixed reviews, many thought the realism meant that the magic was sacrificed thus as was their connection to the story.
Listed below are some other terms you should probably be familiar with:
A cutaway a shot within a sequence of shots that interrupts the stream of action, it might correspond with a relevant detail mentioned in order to exemplify a point.
Can also be referred to as the iris, in connection with the similar role. The aperture is an opening inside of a lens that controls the amount of light reaching the image sensor. The amount of light let into the lens is called exposure. The aperture size is measure in ‘f-stop’. A number describing the size of the opening compared to the focal length. The lower the number, the wider the opening and the more light allowed through.
And there we have it, just some simple and commonly used terms which you might come across. Make an attempt to know as much as you can through production books or even just other online sources, that way you sound wonderfully skilled.
