Somerats may remember that waife and I appeared briefly on A Place in
the Sun a few years back. For reasons that will soon be apparent I
uploaded the clip to YouTube and within minutes had an email that said
that because of copyright the video was not available in the UK and
associated territories.
I completely understand and accept that, but what surprises me is that
they were able to detect it so quickly. How did they do it, was it the
name I used, is there some metadata in the video that identifies it or
did they use face recognition or something (not us silly, the excellent
presenter).

Did you upload a bit-for-bit copy of what was broadcast, or did you
transcribe it to another format? The broadcast stream probably includes
identifying metadata such as a unique ID for the channel.

I was sent a DVD of the whole program and iirc I copied that to my
laptop and used MS Moviemaker to edit out just the clip that I wanted
and saved it as a WMV.

So I guess that's bit-for-bit copy of what was broadcast...

I think it most likely the name you used for the clip (i. e. the same as
the programme). You could soon check this by uploading another clip with
the same name, but which was all your own work.

How did you generate the clip: just capture from the video stream? Did
it include a DOG (digitally-originated graphic, i. e. the programme
logo, usually at top left these days)?

That's fascinating. 1m 12sec rather knocks out my theory that some sort
of checksum is involved. I don't know how they spotted it but whatever
they do, maybe they use the same techniques to identify terrorist videos.

It works fine out here.

Viewers in the UK could try using the network stream function of VLC
media player or one of the many YouTube downloaders such as
clipconverter.cc getvidnow.com or nsfwyoutube.com - the latter is also
handy for bypassing age restrictions without having to sign in.

My thought was why do they NOT use it to identify terrorist videos and
block them within minutes as well :/

The terrorists aren't quite so obliging when it comes to embedding

I was about to write "It's nice to know that at least onerat has
confidence that I won't lose the 2018 BTNs" when I noticed a follow-up
so I thought I would just check what that said before continuing with my
post.

Harrumph! I'm now tempted to refuse the Nomination, Brritters! But as
you have been my champion in the past I will let you off this time.
Don't let it happen again! (And I'll try not to, too.)

Nomination accepted, Mr O.

On a more serious note, I'm dismayed to find how much trouble you can
get into for making fun of evil people. Latest clampdown seems to be in
Spain where even the UN says their laws go too far.

Its called Content ID and relies on the original artist having given
youtube a copy of the file and asking them to look for audio and or
video matches, of any part of it (even still frames).

More details here
https://support.google.com/youtube/answer/2797370?hl=en

(I don't suppose this service will be free to the originator, and I
don't suppose terrorists will be highlighting their output to YouTube.)

Some security researchers have also suggested that all major TV and film
companies embed a very subtle watermark in their video and or audio that
YouTube use to match a database of watermarks, enabling very rapid
identification.

Astonishing. Next you'll be telling me that British soldiers no longer
have to wear bright red uniforms and tall hats and stand up straight on
the battlefield. What is the world coming to?

Although, not understanding this embeding business, I rather assumed it
was a tag added to the file but I'm now getting the impression that it's
more like the word Blackpool which works its way through a stick of rock.

Not a bad analogy. File headers with tags and other information are fine
for files as they have a well defined start. Formats intended for
streaming over the internet or broadcasting need to keep repeating the
information so it's present whenever you tune in.

Another related topic is video "watermarking", where the aim was to add
information to the actual picture, in order to prove copyright theft when
bootleg videos were seized in a raid on a market stall. (That's how long
ago the idea was popular.) The problem is that a visible watermark annoys
the legitimate viewer and an invisible watermark can be removed without
affecting the picture. Removing invisible information is pretty much the
job description of a video compression system such as MPEG.
