Warning: there is flash photography in this report

Why not get rid of it before broadcast? Electronic flash is of very
short duration; much less than the maximum exposure time of one video
frame. So, they could insert a device/program that would look for a
frame with much more brightness than the previous one, and would replace
that frame with that previous one, or with the following one. This could
even be done on live broadcasts.

So, why isn't it done? It would be better for the epileptics, better for
the non-epileptics, and would get rid of these boring warnings.

Er, but to trigger fits doesn't it require a constant repeat rate of
7-12Hz - flash, no matter how much of it, could never achieve that?
How come they always warn of flash but they NEVER give any warning
about blue lights on emergency vehicles be it in news reports or drama
and which are much more constant and of longer duration?

We had to remove strobes from TV masts for (supposedly) the same
reason, but they didn't in Europe and I don't hear reports of
Eplilepsy issues. They only ever flashed at about 1 every 2-3 seconds
anyway.

Do-gooders who don't understand - again!

It's the same with lightning in storms, no warning in weather forecast.

It's Ofcom, they don't set standards for anything useful, like minimum
bit rates, or ensuring uniform audio levels, but instead rather dogmatic
directives like this.

As you say out there in the real world are no end of epilepsy risks.
Dodgy lamp posts, sunshine through railings as you walk along etc etc.
TV has been a flickering box in the room for almost 80 years now, I'm
sure those at risk are well aware, and don't need warnings broadcast
before every possible instance ?

Most cyclists who bother to use lights have the flashing LED type.

I don't recall any epileptics collapsing as a cyclist rides by.

How the lightning always comes a fraction of a second before I blink?

Probably as is the case with most things, not enough people are affected so
they do not see a need.

Besides, when you get such a warning what are you supposed to do, just close
your eyes?
I'm sure there is a pun here about peanuts in bags saying may contain nuts
on them, but its eluding me at the moment.

The other night I was laughing at the announcer every ad break stating that
the following item contains very strong language from theoutset, and has
nudity and violence.
I thought to myself, like most stuff you get these days then.
I'm waiting for the one to say, the following program contains cultural
norms that are considered politically incorect today. If this might trouble
you then please turn off.

Maybe we should just print a warning on every birth certificate and
have done with it. "Warning: the following years of your existence may
contain strong language, nudity, scenes of an explicit sexual nature,
and things you may find offensive or disturbing. Welcome to life".

I've often wondered if, under current legislation, these flashing
lights - plus those on a helmet or a back-pack of the rider - are
technically legal?
