@PeowPeowPeowLasers I know, hence my use of the word "fangled"

@AidanLunn only amateurs use autofocus.

Just use something like keepvid, that should work.

I have tried to download this video ten times. It fails every time, why ?

Yes, it's true. I think it's probably more accurate to say that the effect was the result of the (picture) tubes vibrating, rather than any valves. It happened quite often in high level sound environments such as rock concerts or even at motor racing. The effect is called "Microphony".

Earlier this year I emailed an retired BBC VT engineer via the web site VT oldboys. It was regarding what I thought was some sort of Cross talk taking place when loud noise took place with a studio scene. Dads Army episode the 'Deadly attachment' a machine gun is used in studio. The result was horizontal lines rather similar to Quad Equalization or line pairing with UHF analogue sporadic reception. Apparently the sound energy rattles the valves in the camera ! hence the effect.

@AidanLunn *just as

@BBT609 Practically all of the technology has changed. Valves (tubes to you Americans) have long gone (these things used E88CC tubes in the head amplifier stage), and plumbicon pickup tubes went out of fashion with broadcasters about 20 years ago, jut as with Vidicons, Orthicons, Leddicons, Saticons, etc.
They now have some fangled thing called auto-focus, they have image stabilization technology, they don't even need film or tape to record to! Plus many more changes!!!

@AidanLunn hahaha. Cameras are very interesting pieces of equipment. What in the cameras then had changed now?
If my eyes don't deceive me, I think the guy speaking is John Henshall who was then a cameraman. I suspect this is Lime Grove? I think the comment about being a terrible presenter is very unfair. With no presentation training or skills, I think he delivers an enormous amount of useful information over a very short period.

@tvcams Yes you are correct on both counts, John informs me that it was recorded in Studio E at Lime Grove.
Yes I have to agree with you re the negative comment on John's presentational skills, in John's words ' In fact it was my first experience in front of camera'. Well in my opinion it was job 'Well Done' from someone who was more used to being behind the camera.
