Movie Blurays: Pros and Cons

[Cheapjack]

You've all just said that it is categorically impossible to transfer between formats.

Saving the film, as everyone who has ever taken a photo, knows, is the way to go. And, if a program comes along that can save you a bit of time and money, for an upcoming intermediate format, is the most likely option, rather than going and getting the film back out again.

Well done. You all wound me up for a good 5 hours. Good job.

The review actually states that the output looks worse than the original.

An iPhone is HD? Since when is 320x480 or 640x960 considered an HD resolution? If you can't even get basic facts straight no wonder you are so confused about the Trek blurays

You can get HD on an iphone now:

TV and video

• Video formats supported: H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

Thank you.

No, thank you for completely missing the point (once again).

An iPhone can decode certain types of video that are encoded at 720p, but it cannot display them at that resolution. It has to downscale the video while decoding it.

Like I said many pages ago. You can say the words, but you don't understand what they actually mean.

You've all just said that it is categorically impossible to transfer between formats.

Not a single one of us has ever said that. You really don't understand the first thing about the topic you are trying to discuss.

Oh, and you are still trying to use this as evidence.

Crap. They haven't, Look at number 4. It's exactly the same balance colorwise, as my DVD copy

Once again.

Blu-Ray

DVD

Now I know to your self admitted superhuman eyes and your 1000 line Apple monitor the colors on these shots are the same.

However using my HDTV, my copies of both the DVD and the Blu-Ray I can assure you that the colors in fact are slightly different.

 

[BillJ]

You do know that Blu-Ray and HD-DVD both use essentially the same codecs...

You've all just said that it is categorically impossible to transfer between formats.

You must have missed the nugget above and my earlier posts listing reviews from HighDefDigest.com

Obviously you're purposefully trying to make Blu-ray look better. You lying liar.

The "ignore function" is your friend.

On UK's channel five show, in 2008, they put 'Ironman' standard in a bluray player, upscaled it, using a predictive mathematical algorithm in the DVD player. They watched it on a screen, upscaled. They put in a Bluray, taken from the film master. They watched it. They came to the conclusion that there was not much difference between the two, but recommended bluray as the slightly better option. The whole program revolved around the concept that it is possible to use predictive mathematical algorithms to guess, generally, missing pixels. They accepted it happened and blurays can do it.

I have given sites where they sell programs that do it. I have given examples of sites with image processing predictive mathematical algorithms.

You can get mathematics programs that predict stock market fluctuations, now, you can even model chaos, water, fluid flow.It's not perfect, it's just a general guess. You can predict, to small accuracy, lottery wins, using statistics. People have done it.

I think these DVD's are just processed standard DVD, and there is a lot of evidence for it.

There's a world of difference between "predicting" and "guessing" the missing pixels and actually knowing what they are!

 

[Cheapjack]

Exactly. which is why it is better to source from film, cos upscaling is just guessing. Look:

Image processing

• Connected component labeling: find and label disjoint regions
• Dithering and half-toning
  • Error diffusion
  • Floyd–Steinberg dithering
  • Ordered dithering
  • Riemersma dithering
• Elser Difference-Map Algorithm: a search algorithm for general constraint satisfaction problems. Originally used for X-Ray diffraction microscopy
• Feature detection

• Seam carving: content-aware image resizing algorithm

Scroll down to image processing. There are dozens. There will be one more, when I do my OU degree.

Cheapjack, no matter how many links you post, no matter what you say, it doesn't alter the fact you haven't seen the BD's for yourself - you don't own a BD deck. Your words are hollow and empty, can't you see how futile it is. Your entire argument is based on hearsay and supposition - again - you have not actually wached the BD's. I await your reply and more insults no doubt. Oh, STILL waiting for your reasoning reference my avatar. All the best.

 

[Trekker4747]

Mu understanding is that it was the digital copies the BDs are based from have resolutions far deeper than what even BD can show. There's no need to go all the way back to the film. They had the digital copies of the movies they made when they went to DVD, digital versions orders of magnitude better than what BD can show. Did the soften things and go to far in some aspects with the BD versions? To much color correction and stuff like that? Yeah. Sure. But they're still BluRay resolutions with BluRay detail and are no way shape and form connected to the DVD versions.

 

[Cheapjack]

It's just interesting to hear all this denial. Why was the thread started up in the first place, and even the most mathematically challenged have more than a shred of doubt as to their origin? I've been looking at those screencaps for a year, on a 2 million pixels screen high def.

Given the weight of evidence, and my eyes and the whole origin of this thread, I would say there is a high probability, given the price of the Blurays, too, that you have just got your money's worth. Processed standard DVD put through a highly expensive program, but just standard.

Trekker, please give a few websites that detail these 'high definition, nearly as good as film, 1990-2000 copies, that have exactly the same colour balance as DVD's form the 90's, video transfers' come from? Please give proof that they had even better than ultra high def in the 90s-2000's, when they're still getting ultra high def now and working on it, and everyone keeps their film negatives in a safe place?

Thank you - the pertinent point I think. Please return to this thread when you have watched the BD's. All the best.

There you go Cheapjack. The set for $55 dollars and you can get a Blu-ray player for under a hundred. Then you can actually have an informed opinion on the quality of these transfers.

 

[Cheapjack]

I already have an informed opinion. Informed by about ten websites and 20 algorithms and a year looking at screencaps on an HD monitor. And, pardon, me, I'll be waiting till they rerrelease them.

In fact, I wont. I'll write my own algorithm, stick it in my PC and watch them myself, as any good trekkie should.

I don't think it likely they are some sort of 'near film quality' transfers , taken in 2000, on some hypothetical system, that has never been documented, when they have 50lbs of film cans, which I would like to possess.

 

[JarodRussell]

LOL, is this thread still going?

Sorry, but after reading all your posts in this thread, I'm beginning to doubt that you even know what an algorithm is. You sound like a guy who puts a computer screen on a copier to print a text document.

 

[Cheapjack]

I've written simple algorithms. I wrote one that drew a sine and cosine and and tan curve graph, going on stuff I'd learned at 19 and never forgotten.

I'm informed, you see. I keep up with things. I don't just turn up for work and do whatever is required of me for the day, like some.

Par for the course with this post. It makes no sense, and has nothing to do with the discussion at hand.

I noticed a few posts ago you once again mentioned that the DVD and Blu-Ray have the same color. Do you have images in your browser turned off? It's the only explanation for your extreme ignorance.

I thought he was trolling. But I read his posts in other threads. He isn't.
