IT’S TIME TO SEEK OUT NEW TRADITIONS [516]

A frame from a digitised VHS copy I made of Man Ray's "Le Retour à la raison" (1923)

The time has come for a manifesto because, while we continually live in interesting times, I have realised now is the time for me to codify the lessons I have learned. This is a first draft of my creative viewpoint, not just rules to follow. I shall return to this.

FIRST VIDEO MANIFESTO 


“Video”: Latin, “I see”

 

This world is man-made. There is nothing else to blame.

 

This world is created with images, and the more of them you take in, the better.

 

This world is described by images. Add to them.

 

This world is remade using images. This habitually ties everything into politics.

 

This world is yours, not also yours.

 

This world excites you, so keep making notes. 

 

You have a duty to report that excitement, but impartiality does not mandate distance.

 

Create early, edit always, no matter the medium.

 

Crystallise your message in the opening moment. Let yourself and your audience know you are in the right place.

 

Make yourself fully understood, by all possible methods.

 

Make it concise, or keep it short.

 

Put your name on it. Your insight has value.

COLOURS OF THE WORLD, SPICE UP YOUR LIFE [360]

Left: digitised VHS source. Right: colour boosted in video editor.

Having completed my video about Memphis furniture [link], I am confident I have made a well-structured piece of television with good use of archive material, but I also learned how terrible the Video Home System (VHS) really was.

Having decided to include a fake advertisement break that reflected the influence of Memphis design, I realised that the recordings I used literally paled in comparison to my photographs of the real-life furniture. I already needed to boost the colour of the Weetabix ad I used, using a different VHS copy of it for reference, having being unable to find a copy that was higher in resolution and also not muddy in colour, but then I realised the colour of Warninks advocaat is yellow, not cream, and the swimming pool ladder in the Kitekat ad had to be brighter to match the more obvious influences in the colours and patterns used.

This is not a case of my digital photographs versus (the digital sample of) an analogue tape, the relative age of the tape, or the decline in quality of the recording over time, but more the technical limitations of the VHS format that have largely been overcome by the switch to digital formats, through no longer being constrained by a physical form.

On a 12.5mm-wide VHS tape, the top 0.65mm is taken up with one or two audio tracks, and the bottom 0.75mm is a control track used for synchronising recording and playback. The remaining 9mm is used for the picture, with a signal bandwidth of 3 MHz for luminance – the black-and-white signal that forms the picture - and a 400 kHz sub-signal for chrominance, reproducing the colour. 

These numbers obviously doesn’t mean a lot by themselves, except that less space on video formats are reserved for colour signals because your eyes react more to changes in brightness, so a colour signal can be compressed more without much change in colour. However, the bandwidth of the original TV signal being recorded is much wider, with the PAL video standard using 5.5 MHz for luminance, and 4.43 MHz for chrominance, SECAM using 6 MHz and 4.43 MHz respectively, and NTSC, broadcasting a 525-line picture instead of 625 lines, using 4.2 MHz and 3.58 MHz respectively. 

In order to fit your recording onto the tape, VHS has to throw much of the signal away in a manner that befits having tape only half an inch wide, playing at 1-1.5 inches per second – older professional, broadcast quality tape standards like 2-inch quadruplex, 1-inch Type C and U-Matic recorded a better quality by simply having more surface area to play with, running a wider tape more quickly to pick up as much information as possible. The later S-VHS standard increased the luminance signal recorded to 5.4 MHz, but kept the chrominance signal, and the speed of the tape, exactly the same.

While the picture quality of the contemporary Betamax format was better than VHS, the throwaway nature of TV advertisements often mean that the format that won out in the video format war often winds up as the archive format for those ads. One point of my video as to show how colourful 1980s design was but, without me doing anything with some of the images, another point would have been how our recordings of the decade washed out that colour.

FILL IN THE BLANK [250]


[Please see below for the script for my latest video, as seen above.]

(black screen)

Do not adjust your device, or do not adjust it any more than you already have. Your screen has been intentionally left blank.

However, that might change, so don’t look away either. This is not a podcast, and this is not radio. This is a video.

This isn’t a confidence trick either. Videos need pictures, but my conscious decision to put nothing on screen still leaves a picture frame. I may also change my mind.

Mind you, that frame is never empty – even if your screen is turned off, it still reflects light. In 1951, the artist Robert Rauschenberg painted a series of canvasses with white house paint, but those paintings are not blank, for the brush strokes played off the ambient conditions in the room, and off anyone that looked at them.

The following year, Rauschenberg’s friend John Cage composed the musical piece “4’33”” [pronounced “four minutes, thirty-three seconds”] which of course, is not four minutes, thirty-three seconds of silence: it is composed for any instrument, any band, any orchestra, but while the players do not play, the room, and the audience, plays with them.

Ideally, you want your work to be received hot, rather than cold, but I will explain that later.
I actually found this blank screen online, but in searching the term “blank screen”, I either get this:

(white screen)

Or this:

(black screen)

I recently bought a new television, and the energy-saving options actually affected how it dealt with the difference between black and white. When a video cut from black to white, or even if white text is added to a black screen, my television faded it in instead. For me to see a video properly, I have to turn off all of its fancy processing features... and set the picture mode to “sports,” for some reason. So, if I cut to a white screen:

(white screen)

And back again:

(black screen)

...and your screen faded instead, your settings are not acting in my best interest.

Video crosses over with both film and television, but these two media are not the same: as classified by Marshall McLuhan, in his book “Understanding Media,” there is “hot” media, and there is “cold” media, according to how much participation is required of the audience. For McLuhan, film is “hot”: the picture is dominant, and you are ideally in a cinema, so you are captivated by the image, because less is required of you to remain captivated. On the other hand, television is “cool”: there are more distractions, and you have to take account of this before you can start paying attention to whatever is coming from the TV. Films can be shown on television, but “hot” media cannot be rendered “cool” – making it harder to focus on a film may make it impossible to watch, missing out on detail television knows not to include.

When I next make a video, do I want to be hot, or do I want to be cool?

Thank you for watching. As ever, the nostalgia culture crisis continues at  [www.leighspence.net].
