Wouldn’t mind being a set top box company right about now

Well, pensioners will be receiving $AUS300 million worth of free digital TV receivers, eh? I wonder if they’ll be HD capable.

The Fifth Element on Blu-ray

I have a Blu-ray test disc of The Fifth Element to whoever, with an Australian postal address, first asks for it in comments.

This was the original Sony release in Australia of the movie (it is now handled by Madman Entertainment). The video on this disc is identical to the US remaster and to the Madman re-release.

No proper label, no box, no slick. The movie, though, is fine.

‘One data point and you’re jumping for joy’

This is just a bit of fun, really, but I love it. You get a bunch of academic economists who want to spread the free enterprise message and they create a rap video: ‘Fight of the Century: Keynes vs. Hayek Round Two’. A second one, actually, as the name implies. The lyrics are brilliant, and (from my point of view anyway) the (in)justice of the battle is well reflected. Plus, just look at those production values!

If you know a bit about John Maynard Keynes of Friedrich Hayek, two of the great economists of the 20th Century, you’ll get even more out of it. (Two of the latter’s most famous books were The Road to Serfdom and The Fatal Conceit. The second of these profoundly influenced my own understanding of the world. The End of Laissez-Faire was written by Keynes.)

Hayek was a Nobel Prize-winner, and I think few would disagree that Keynes, also, would have won had the Economics prize been instituted before he died.

So, enjoy:

Incidentally, the security guard at the start is Mike Munger, an economics & political science professor at Duke University in the US. I’d love to go to his lectures, because he seems to be as funny in real life as he is in the video. For a sample — and an opportunity to learn some economics — here are the Econtalk podcasts in which he has participated.

The host of Econtalk is Russ Roberts, who was co-creator of the video.

Inappropriate laughter?

No, very much appropriate, despite the every-human-life-is-of-equal-value twerps that abound. Fortunately this doesn’t seem to be a problem in Taiwan. If you’re saddened by Bin Laden’s death, don’t watch this clip. It is highly offensive to all, especially Muslims. I’m neither saddened nor offended.

Update 4 May: Sorry, as Chris notes in comments, this clip has been made ‘Private’, whatever that means. As far as I can see, you can’t play it even if you log onto YouTube. Pity.

Politically correct Bee Gees

When I was quite young (about 13) my father sometimes worked at a second job as a security guard. On one occasion he had a job at a concert of the Bee Gees at the local theatre. My sister and I went and enjoyed the show for free. This would have been around 1970/71, well before the group’s second incarnation in disco (courtesy of Saturday Night Fever).

The three brothers constituting the Bee Gees were born in the UK, but formed their group here in Australia, where they were largely brought up. Musically they were very precocious, and I have a CD with a number of very well developed pop songs they did when they were mostly still in their teens.

One track that had eluded my collection was somewhat of a hit in Australia, called ‘Spicks and Specks’. Indeed, there’s a pop/rock music quiz show on the ABC named after the track, which refers ‘spicks and specks’ of memories.

So I hit the Apple iTunes store this evening to purchase the track. I searched on ‘Spicks and Specks’, and the result came back with a number of options, all called ‘S***ks and Specks’.

Political correctness gone mad!

Oh, incidentally, don’t buy the friggin’ track. I did, and it’s awful. Not the song, but this originated from a scratchy vinyl recording. Nasty stuff.

Death on Oz?

Incredible! I’m listening to a recent episode of the Skeptoid podcast, this one on Hollywood myths. It turns out that some people actually believe that the suicide of a Munchkin was recorded on film in The Wizard of Oz. Brian Dunning, the producer of Skeptoid, says where the alleged hanging body can be viewed, and suggests that it is most likely one of the birds they had on set.

I immediately thought ‘Blu-ray’ of course, so I popped in the disc and watched the section he mentioned. And all I could see was what was bleeding obviously a bird. A large colourful one. I don’t know my birds at all, but it seemed to be some kind of crane, largely black or very deep blue, with a yellow crest on its head and yellow and white wings.

Don’t believe me? Here’s a grab from the Blu-ray, or rather crops from two of them. Soon after this the camera backs up a little (as the trio of performers approach it), making the bird a bit smaller in frame.

Wizard of Oz - a bird, not a body

Now the group turn around and start dancing back up the path, away from camera. At this point the bird changes its posture from one of pecking stuff from the ground. To me, it looks an awful lot like the bird is watching the trio approach, as birds are inclined to do:

Wizard of Oz - a wary bird

As you can see, as the bird becomes more upright to see (as I imagine) what’s approaching, its neck comes to align with a tree behind it (probably not a tree, but a painted tree on a backdrop). All detail largely disappears, aside from a yellow dot for its beak.

Then as they get closer, the camera pulls back a little more and the bird stands there, watching them, all detail now gone, leaving it as an indistinct black blob wobbling slightly around the tree/painting behind it:

Wizard of Oz - bird becomes indistinct blob

Finally, the dancing, singing crew get close enough to alarm the bird, which opens its wings in what looks like a display of aggression, but may merely be preparation to depart. The reason I say aggression is that as the group move past it, the bird rotates slowly to its left, facing them. This is obvious on the Blu-ray, but here are crops from frames a second or two apart:

Wizard of Oz - Aggro bird

See how the bird’s beak becomes more prominent on the later (lower) frame as it moves more into profile.

With the enhanced clarity of Blu-ray, it’s quite impossible to see any hanging bodies, or anything else other than a large bird. I haven’t changed the screen grabs in any way, other than cropping them down to size. These are what you’ll see on the screen.

So how did some people come to be believe anything different? Well there are two parts to this: one that makes sense and one that’s irrational. The part that makes sense is the fact that in most previous versions of the movie, it was nowhere near as obvious that this was a bird.

Many people would have seen this movie in some not easily repeatable format. You only get one chance at the cinema to check out the scene. And many of the repeatable formats are not particularly clear, especially VHS. Check out this one on YouTube, for example:

For some reason it is not only fuzzy, but in black and white. Or this one, which is in colour, but obviously videoed from the TV screen:

Now, to my eye both of these both look like the bird I’ve discussed, because my brain fills in the indistinct image with what I already understand it to be, but I imagine that if you haven’t seen a clearer version, these might be indecipherable to some.

Which brings us to the second part. To believe this claim you have to have the capability of interpreting an indistinct blob as a hanging Munchkin body. That’s the irrational part. Why not — if not the bird itself — a prop swung loose from the ceiling and hanging suspended? Why not some of the fake tree cladding springing free from its glue and waving in the breeze? Why a body?

Of course, a true believer will be able to claim that Warner Bros has covered this up by digitally painting a bird into the Blu-ray version to cover up the suicide, but once you stray into that kind of territory, rational argument becomes rather pointless.

Lots and lots of comments

The other day I mentioned that I had a political piece on the ABC website: Unleashed. That piece, called ‘The real defence exception’, now has 454 comments. Having a look through them was pretty instructive, I thought.

Have a look at my piece, but in short I was suggesting that perhaps we ought to stop thinking of a military career as just being another job, since dying isn’t in the job description for other careers.

I knew that the ABC would be pretty hostile territory for the kind of argument I was making. Surprisingly, maybe 25% were pretty supportive. The nicest one that I noticed:

Thank you Stephen. A lone voice of clarity and truth. This is what many serving and ex-Army readers have been wanting to say I am sure.

Many more were condemnatory. A surprising number somehow managed to extract from my piece that I approve of sexual exploitation of young women, rape on the battle field and military supremacy.

The comment abutting the above one was:

This article perfectly illustrates what is wrong with the current military mindset. You seem to be implying that because these cadets are training for warfare, the normally expected norms of morality regarding sexual behaviour, should not apply, and the commandant in charge of the academy should not be expected to enforce appropriate behaviour and discipline. What a disgusting and immoral proposition. How can you produce “Military Officers, who are prepared to shoulder responsibility of duty unto death” when they are allowed to behave in this reprehensible manner, without any punishment or disciplinary consequences?

I replied to a number of comments the other night. Indeed, I must confess that some ten per cent of the comments (46 of them) were from me, in reply to others. My reply to this one was:

JILL C, I am very sorry that what I wrote could have been interpreted in the way you suggest. I did not address what I actually thought of the behaviour. Nor did I address what I think the ADF thinks of this behaviour.

FWIW, in my opinion this reprehensible behaviour, if shown to have taken place as reported, should result in the expulsion of all the ADFA cadets involved.

My conclusion was that many readers formed a judgement on my piece — and me — based only partly on what I wrote. Much of it was based on the attributes they imagine appropriate to a category into which they placed me. I was pro-military, therefore I was … well, whatever they felt that the pro-military people must be.

Perhaps I should finish by repeating one the replies I made:

… I suggest you re-read what I wrote. You are not alone, an extraordinary number of comments here seem to assume that just because I am making a case for military exceptionalism, I am making a case for male soldiers treating female soldiers horribly. I am not.

Political and other opinion is not restricted to two-dimensions. It is often multi-dimensional. I can (and do), with the reservations due to any Government organisation, support the military and recognise that it is most definitely different in kind to most organisations, while simultaneously holding that behaviour within it which is, in effect, a betrayal ought to be harshly punished.

The next big advance?

So it turns out that Peter Jackson is shooting his Lord of the Rings prequel, The Hobbit, in 3D and at 48 frames per second. Virtually all filming for cinema is done at 24fps of course, and one of the great things about Blu-ray is that it brought 24fps delivery into the home, instead of the bodges used to show film at 50 or 60 fps.

I reckon the jump to 48fps, if continued, will be the first great jump in 2D quality in cinema since the 1950s, when experimentation with large format filming started. 24fps is subject to judder. The eye can perceive the little jumps from frame to frame at this rate.

Cinematographers overcome this by keeping the shutter speed on their camera’s slow. That way moving objects can appear to be moving smoothly, although this comes at the cost of loss of resolution and clarity. This technique is so important that even computer animation employs it. Here, for example, is a scene from Toy Story 3:

Smeared movement on Toy Story 3

Woody is moving rapidly upwards. The edge of the toilet and the corner of toilet paper on the roll are clear, while he is smeared. Pixar puts algorithms into its rendering software specifically to smear moving parts of the image to eliminate judder.

Now, imagine the clarity that would be available if the frame rate were doubled. The eye has much more difficulty discriminating between two pictures seen 1/48th of a second apart than it does 1/24th of a second. Smoother, more fluid movement is generally claimed as the advantage of an increased frame rate, and there is some truth to this. That’s why frame interpolation motion smoothing systems have been incorporated in many displays. But in practice the real improvement will be sharper focus and greater detail of moving objects and of scenes during camera pans.

The article linked above suggests that there are plenty of digital cinema projectors that will handle this higher frame-rate format. I hope so. But it does leave home entertainment behind.

Blu-ray does not support 48p. Some display devices such as projectors may, but I don’t think the current HDMI standards do.

HDMI 1.5 and High Frame Rate Blu-ray anyone?

If 48fps filming and cinema production becomes common, the home theatre must follow. Not just because it is always good to have the same quality as the cinema, but because material shot optimally for 48fps may not look that good at 24fps.

Which also raises the question: how will it look in the thousands of cinemas which use film?

Is 3D TV bad for your health?

That’s what’s argued here. It’s called ‘binocular dysphoria‘, which Wikipedia calls a ‘hypothesized condition’, noting that ‘there is no peer reviewed evidence of this condition’.

If you’re worried, just keep it down to one 3D movie a week.

The many faces of 3D

If anything demonstrates how our senses provide us with a useful abstraction of the world, rather than a photographic image, it is surely the various 3D technologies now proliferating.

The sensation of 3D is a weird thing. At some engine-room level in our brains, 3D things just look like they are in three dimensions. It is a workable model, a construct. This construct in our brain makes it clear that these parts are closer and those parts are further away, and that is the whole point of it.

But there are several different ways in which this constructed sense is triggered. the most obvious is by providing each eye a different view of the picture. That’s what most 3D technologies do. In the real world, this sense only works with objects within metres, tops, of the viewer, because the angle difference between your two eyes is too small for further distances. But that doesn’t stop the technique being employed in 3D cinema and TV to make much greater distances seem 3D. That little subroutine in the back-office computer room in the brain — the one with the sign ‘Video Processing’ on the door — apparently doesn’t care that your left eye and right eye are seeing that an object fifty metres away is in a different position with respect to its far background. It just notes that they are seeing these different views and invokes that ‘3D’ sense.

And how about this ‘Head Coupled Perspective‘ process used on an iPad 2. Its front camera tracks your head and then changes the apparent perspective of the image. Watch this video and see if it doesn’t look 3D to you, at least part of the time:




Now both eyes are seeing the same view at all times, yet it looks 3D. Here is another thing that triggers this 3D sense: objects moving in front of other objects in a way that makes them look closer. Here is another example of that. On my iPad I have a Solitaire game that finishes — when you win — with an inane congratulatory message. It bounces up a down a little. Meanwhile, little hearts and clubs and spades and diamonds ascend from the bottom of the screen passing underneath it as they go upwards at various speeds.

All this happens over a background picture. The bouncing text and the card suit markers are all rendered at full resolution for the iPad screen, while the background picture is soft, seeming to have been scaled up from iPhone resolution. Here’s a detail:

Solitaire looking 3D

Sometimes this looks startlingly 3D. In this case, I think the trigger for the 3D process is the movement of sharp foreground objects over a slightly out-of-focus background, which is what you often experience outdoors. Your eyes are focused on something ten metres away and it is moving with respect to the background, which is a touch soft because you aren’t focused on it.
