I've long *assumed* that all previous inches were replaced by the metric
version we know today which certainly is the official inch where I come
from, but... Where does it say all the old ones went, officially?

I've never actually checked myself.

No, that is how the metre is *determined*.

Measurements against the standard are made against the standard, not
against that which determines the standard.

Think about it.

Only at the moment.

That's pretty much the way I feel about my job.

It's great.

I should have gone into broadcast TV after my degree but for various
reasons I didn't. I regret it now.

Although I only did industrial video I agree about the editing. It's
hard to explain to someone who has never done it but putting all the
pieces together was my favourite bit.

Never...

Well... At one time, I used to make the Panorama 30 second trailers. The
reason was simple; there was a terrific shortage of film editors, and
every Sunday evening they needed to make a trailer from the elements of
the Monday's programme. Nobody else had the time to do this; to edit it
*and* to write it, and to choose the pictures. They needed a producer
who could cut film. So it was me. With Fred Emery, we'd play a game.
We'd write a trail, then he'd go into the dubbing theatre and record the
track, jumping up and down with excitement. Then I'd cut a duplicate
copy of the programmme. I had his commentary, a copy of the Panorama
theme music- which was the wrong length but we would write to cover the
join, then I would shove in the pictures. The only rule was, shove in as
many shots as you could possibly get in, then double the number... I'd
usually manage about 30 shots in 30 seconds.

It was hilarious, but everybody loved them...
