Assuming a 32bpp (bits per pixel) true colour image, a single frame would come in at 7.9 MB per frame. Given that film is transferred at a rate of 24 frames per second, 1 second of video would come in at 189.84MB. That leads to a Blu Ray disc being capable of showing about 269 (about 4 1/2 minutes) seconds of video in uncompressed format, which does not include any sound or any other information...melonpan said:

You also have the legacy issue, the huge backlog of old players.
Digital terrestrial TV would be hugely improved by moving to 8k interleave on the DVBT and going H264 but imagine the uproar if suddenly everyone who has bought a freeview box is told "sorry, they are now as out of date as analogue TV, you have to buy another".
And DAB is finally ditching MPEG layer 2 audio for AAC+ but most UK bought DAB radios don't support it
Oh happy days!
It'd be so great if there was an "everything" box, which surprise surprise - did everything!
You only needed to upgrade the hardware to this box every few years, and firmware updates became available and were seamlessly streamed to the box via the Internet in some way or another.

Many thanks for that Gawyn! That's a truely incredible answer, and gives me something I can use to make some interesting calculations with.
So then, a deca-layer Blu-ray disc (which according to Wikipedia is possible) of 250GB could hold 1316.9 seconds of uncompressed video, which is 21.9 minutes of video. That's pretty impressive.
So for a 90 minute film you'd need a 1025.14GB disc, so basically a TB disc - which is what the holographic/protein coated discs are being touted at!
Fantastic! So the next generation of optical media will be able to hold uncompressed video! (Hopefully, and with sound/other things if these discs can go over a terabyte).
(I just hope I didn't muck up the calculations - and of course I have no idea about how to work with bits/bytes in all this so it'll be a rough estimate).

Wait until 2160 goes mainstream, 4 times the data of 1080.

Off topic but I really had to comment. I'm actually kinda stunned Dan(melonpan) that you won't watch black and white films based purely on the video and audio quality. There's so many fantastic pieces of cinema you are missing out on by ignoring them. Open your mind a little and forget about the quality for a while and just enjoy some great storytelling.
Psycho, It's a Wonderful Life, Metropolis, Mr. Smith Goes to Washington, Harvey, The Last Man on Earth, Hobson's Choice, The Little Shop of Horrors... the list goes on and on and even into television series. One of my favourite series is Steptoe and Son and that was mainly recorded in black and white. The video and audio is bad quality but it's the show itself that shines through. In this case it even adds to the character of the show which is something the colour episodes were missing.
Don't dismiss movies because visual/audio quality. It's weak and ignorant reasoning. If you watched some you might be surprised.

I've watched my fair share of black and white films.
I'm currently being subjected to one in 'critical thinking' lessons, about some priest that was wrongly accused of murder, because he listened to someone telling him about it, etc.
I just really don't like the film, it does nothing for me.
Steptoe and Son, I've also seen quite a few episodes of this, I don't find that especially funny either, it generally annoys me.
The whole style of old films just does nothing for me, they're from a different era, with different opinions/views of that era, which I don't like.
I'm not being ignorant here - thanks, it's not like I refuse to watch an old film, I'd watch one if someone wanted to show me one, or if there was nothing else to watch. Maybe I didn't make myself clear in a previous post.
I guess I associate old films with old times, and old mind-sets. If you can recommend a film that doesn't show this, then I'll look out for it.
I also hate the way mostly all films from earlier than 1970 are rated 5 stars, in TV listing papers. That really pisses me off. I'm totally against the whole - that really old film had the idea first, so it gets 5 stars but everything else made like that in the same genre is not worthy of anything near.

I take it you mean the way date is numbered as in Kb/KB. Why would it be doubled? Surely you'd just go a step up to the next power of 3?
I'm sure I've got the wrong end of the stick here.

2160 HD resolution. ie 2x the lines of 1080. Some screen manufaturers have started work on it but its not an official standard yet.
Project-2501 said:
Oh right.
So that's the digital cinema resolution it seems. That's pretty awesome.
I think 4096x2160 will come along with 7680x4320, in the next generation of media though, as both are too big for Blu-ray discs (maybe it'll be just about feasible if they make that deca-layer one).
This picture just makes 1080p look like nothing.
Melonpan: I suggest you watch some old Hitchcock movies and Havey for some brilliant black and white cinema. There were some fantastic old episodes of the Twilight Zone as well, brilliant storytelling there. Have you ever seen Rear Window? It's not in black and white but it's one most fantastically executed minimalist suspense stories ever put to film. It's not in HD but you should give it a try anyway.
Yes a lot of movies from way back when haven't aged well and are dated to a certain era but there are many that have and are timeless pieces of cinema. They shouldn't be ignored. To dismiss movies because they're from a certain era is crazy but it's just as crazy if people mindlessly praise films just because they're old. Some have faired well over time, others have not.
That's all. I'll let you lot get on with talking about HD statistics.

Perhaps someone with more tec knowledge and a lower blood alcohol level could also answer this. How many Hi-def episodes could you fit on a Blu-ray disc? Cause judging my the Hi-def fansub's I've found you could probably fit more episodes per disc than conventional definition episodes on a DVD. If this is the case even if you don't go for the hire quality the price per episode might be tempting. Also since it will more affect newer releases doubt many of us will re-buy all the old anime we own.
hopeful_monster said:
You could fit as many as you wanted on, if you compress the files enough.
Thinking properly though, the average DVD has about 4 episodes per disc, so considering a dual-layer Blu-ray holds 50GB and a dual-layer DVD holds 8GB, 4 episodes/8GB, that's about a 25 episode series on a single disc, at the same bitrates being used at DVD.
I could never see that happening though, there'd be no reason to opt for a lower bitrate and therefore quality, when you could spread it across more discs.
I've written multiple things here then erased them, because it all comes down to many different factors - the producer/distributors way they want to release (i.e Funimation want to go straight to boxset and may opt for a lot more episodes per disc (I mean why wouldn't they, their quality is crappy enough already!)) - the materials they have - the resolution the show was animated at.
You'll just have to see, no one knows. I would say Japan would be a good indication, but so far they have released no TV series on Blu-ray, only some movies, and they'd never go for more than 3 episodes per disc anyway, so that's not a good indication - although it may be to some extent because R1 will probably follow suit (not the 1-3 episodes per disc, but R1 will keep to what they're doing now).
Most of this post is speculation. D'oh.
Maybe I've completely misread your post.
