Bond: DVD Vs. HDTV *100Mbit Warning*

Thought some of you might be interested in seeing these. DVD caps are from R1 or R2 SE's. HDTV caps are from Voom HD broadcasts and are made from the same masters as the UE's. Didn't take any of the caps myself, can't be bothered!
And worth noting that Bond on Bluray will look a whole lot better. Better codec and higher bitrate.

WOW thanks Lourdes.
However as the DVDs are from the inferior SE masters and the HD the Remastered UE masters it's not a fair comparison. I'm not sure I'm seeing a UE or HD improvement.
Why have the DVD captures been enlarged to the HD resolution? That would affect picture quality too. That's not the native DVD resolution.
Also at such a large resolution it shows me very little other than the obvious improvement in Picture Quality. I can't get an overall judgement of how they compare as everything is so huge and not in perspective. I think links or the Image Shack thumbnail button would've been better. That way the browser (if using links) would auto-resize to the browser window and you could see which is better. No offence but all we have right now is huge heads and no perspective.
I hope I'm not coming across as derogatory just some healthy criticism.
I presume the HD prints are from American TV? Lucky or what.
p.s - 100Mb, don't you mean 1Mb? Broadband of any speed pretty much will suffice.

Can someone explain to Brad why downscaling would be pointless ?
I've tried several times without success.
It's like talking to a thick brick wall...

I was just posting them to show the nice difference resolution makes.
Upsampling >>>> downsampling. When you downsample you're ditching pixels and should never, ever, ever, ever do it.
When you upsample you use bicubic interpolation to gain resolution.
You're actually getting an IMPROVEMENT in quality.
And photoshops bicubic resize is one of the best around.

@Brad:
If you need proof, here it is:
Both of the following caps are at DVD resolution.
Due to the downscaling, the HD picture loses all its detail.
Both caps now look like they have the same amount of detail (even though the HD cap is much sharper in reality).

1280x1080i? I do hope you mean 1920x1080i! Otherwise we would have
very square Bond films!
Looking at the size of the HD images, you mean 1920x1080i. I think you're getting the resolutions of 720p & 1080i confused!
1280x720 & 1920x1080 are the correct ratios.
Thanks for the comparison though, although it would be better if the Ultimate Edition DVDs were used. It would've been a fairer comparison.
Maybe someone can add captures from the Ultimate Editions of the same frames seen in this thread?

No. It's 1280x1080, It gets scaled to 1920x1080 by the receiver. Saves bandwidth.
I'll give you an extreme example.

Not too bad for something that lost nearly all it's H res eh.
Sort of like the way in which anamorhpic DVD's work. They're only 720x480 or x576 but get scaled to 854x480 and 1024x576 respectively. But with them it's a cunning way to squeeze in more image. HD Lite is to save broadcasters bandwidth. And with good scaling it doesn't look at all bad.

Ah, I didn't realise they were transmitting at 1280x1080.
It does make it seem like they are cheating us out of true HD images though! Its almost as if now that we have enough bandwidth to move from interlaced to progressive pictures on TVs, they're now doing it the other way to save bandwidth on the width of the image instead of the height!
Grrr!

1080i isn't 1280x1080... simply because 1080i transmits 540lines every other field. (Which is why there's a "huge" difference in vertical resolution between 1080i and 1080P - of course depending on source material... film will look good, video won't... though BluRay/HDDVD at 24fps 1080P WILL
).
So if HDTV truly transmits 1280 width and stretches it akin to how 720 pixels are 16x9 stretched on DVD then I can truly understand why people say 720p looks better than 1080i (as 1280x720 probably is better than "interlaced" 1280x540 scaled to 1920x1080)
Though your example was VERY extreme
