HD and "720" refers to image resolution. Not to the audio.



Not entirely - drop 'hd audio' into YT for a search.

Try this one (for instance):

Listen to that compression! (dynamic, not bitrate). Nothing remotely "HD"
about that clip :-(

This use of the term "HD" to refer to audio is a new and unwelcome
phenomenon, a BBB (Bull**** Baffles Brains) ploy on the part of companies
who should know better. It seems to refer to the use of lossless coding, but
wouldn't it be so much more accurate (and informative) to say "lossless"
rather than "HD"?

"720", of course, is a reference to the pixel height of the image, and very
clearly bugger-all to do with the audio.

I know. See below.

Calm down, dear....

I'm fully aware of the 'HD' definitions for image sizes/pixel count and
have/had been wondering if the video quality (pixel count) is in some way
connected to the audio quality - BY THE YOU TUBE SETUP, not by me or anyone
else in this instance...OK?? The 380 video claiming (and sounding) to have
'HD Audio' I linked above appears to infer that you can have 'HD Audio' (in
YT terms) on an SD video, so then perhaps it doesn't...

FYI, I have been working with '2K' (1920 x 1080) movie media for probably 18
months or more and have progressed through 480, 576, 720 'HD' and 1080
'Fully HD' digital projectors in my own home. But that's as far as I will
go - have a read of this to catch me up before you continue with your usual
trick of trying to pounce on erroneously perceived errors:

http://hometheaterreview.com/five-ti...nema-standard/


If 2K is 'Fully HD' WTF is 4K? - 'Overstuffed HD'...???

Oh, and before anyone else starts of the notion of 'HD Audio' not being
better than uncompressed LPCM, let them do their own Googling to see who
exactly sets what bitrate as 'HD' and where (we know why) they do it....

Rock on....

As that article correctly stated, "2K" and "4K" refer to professional cinema
systems, not domestic systems such as BD. "2K" is 1080 x 2048, not 1080 x
1920. OTOH the terms "HD" and "Full HD" are never used in the world of
D-Cinema but only in the domestic area. So what you have been playing with
is 1080p FullHD, not "2K".

You are right, it's 'Full HD' not 'Fully' (says so on my PJ) otherwise,
stoppit David, you're busking. Try this:

http://www.myce.com/news/youtube-4k-...g-video-31768/


And, it seems, bristling for an argument which you won't win (you never do)
and I'll get it in the neck for not letting you!!

:-)

Anyway I'm only interested in the *heavily on-topic* audio aspect here and
the only thing I have discovered so far is that video HD appears to be not a
requirement...??

Savvy?

Peace and Love

The difference between us is that I don't believe everything I read on the
internet!

There are so many errors of fact on that page that it's hard to know where
to start. Firstly 4K pictures are 4096 pixels wide, 4096p would be 4096
pixels *high*. IMAX is a film format - 70mm film run sideways so that each
frame is 15 perfs long. Two 2K digital projectors would come nowhere near
equalling the definition of that!

I'm currently in the process of buying a 2K projector, not for me you
understand but for a cinema. Which is just as well as the £35k + VAT price
tag is not something I'd want to pay out of my own pocket. :-) ( 4K
projectors are, of course, a hell of a lot more expensive. But only needed
for really big screens).

So, unlike you, I do know what I am talking about.

David.

Rubbish. I believe even 60s James Bond movies are being digitally remastered
at 4K these days.

What, because you are buying an expensive 2K PJ?

I've got two here already but 'domestically priced' (resolution doesn't go
up with the price tag), so I'm sorry to say I disagree - looks to me like
you've been Googling like a mad thing!

Anyway, I'm not getting anything very *constructive* from your posts, so
I'll speak to Ken now, if that's OK with you!

I could write quite a bit about the difference between home/boardroom
projectors and large venue projectors. But someone who is into 2K wide
projectors could probably do it even better.

Not irrelevant to the point that that web page, which you seemed to think
significant, was full of inaccuracies.

The D-Cinema specification allows for both 2K and 4K films, and 2K and 4K
projectors. 2K projectors are intended for screens up to about 10m wide, 4K
projectors for those bigger than that. A 2K cinema projector can show 4K
films down-converted perfectly well, just as a 4K projector can show 2K
films up-converted. Of course this also means that 4K projectors need more
light output. They use lamps from 4 up to 7kW, whereas 2K machines
generally have 2 or 3kW lamps.

So, unlike you, I do know what I am talking about.

They are domestic projectors, and have as much in common with a D-Cinema
projector as a cheap cassette deck does with a pro reel-to-reel tape
machine.

Google doesn't enter into it! My information comes directly from industry
sources.
