you are right but at the same time you are completely wrong. Specs are specs but there ends up being a lot of "interpretation". What you need to realize is how compression works. For this I will limit myself to three things
1) blocking: instead of saying pixel 1,1 is black, if it's neighbours are black that will be saved as a block so the whole block is black
2) moving: this has to do with b/p frames, basically a blob of pixels is moved (the equivalent of cut and paste) for example in this icon, why redo the whole head, just move it a few pixels
3) changing parts: this also has to do with b/p, but in essence is just changing the pixels that need changing so if I use this icon so all the info that is needed is the few pixels that become the whipping whip and the ones that change back to background the rest of the frame remains the same.

Now at the same time you have 24 frames a second and 1080x1920 worth of pixels to compute for each one of them. Sometimes the data might not get there in time, other times it could be a rounding error (with movement) other times it missed something..... and these add up over time between i frames. Now in theory this should not happen, but theory and reality are two completely different things. This will be much more apparent and easy to see in stuff like digital OTA or Sat where weather can sometimes help with missing some info. If what you said was right then that would never happen even in extreme weather examples like I pointed out (it would be there or not).

If you really want to know...2002 top 10

By the way, for those followers of “Xylon” who refused to reward the studio that gave you Baraka on Blu-ray by refusing to purchase the disc since, how did “Xylon” term it… something like ‘the only thing good about Baraka is the soundtrack’, is that a more or less correct quote Monkey?

Anyway, don’t ever say I didn’t do anything for you guys.
Here’s a heads-up for tomorrow evening…

Make sure you bring your cameras.

FROM ANOTHER THREAD Any truth to this?
I don't get sucked into stupid arguments with people who think they know everything about the film industry ( which I work in). When you do a direct transfer of a compressed DVD Video to a High Def format you have to upscale by adding pixels and those pixels are digital and not from the original film therefore they don't have the same characteristics as film so they appear as digital noise like with a camera at high ISO. This is why some Blu-ray movies are only $10 a week after they come out and others have been out for a year and are still over $25. A lot more goes into a high quality release making it cost more. I have found the easiest way to tell a crappy transfer from the good is the size of the BD. If it is a 25gb disc then it is an upscale 9 times out of 10. 50gb is a fully rendered transfer with minimal to no compression and will cost quite a bit more money.

[Jeff Kleist]

No

There are so few upscales out there it's barely worth mentioning, and no major studio does it with their movies

^^^thank you Jeff

Where was that from?

I am curious as well. None of what he says seams to make any sense as quoted. except for a pirate, I can't imagine any studio starting off with a compressed file? A Master done for DVD or TV, especially if it was done in 2K, yes, but a compressed DVD?

Ah, fair enough.

OK, I give up and agree with everybody.

Almost any movie filmed pre-bluray will be upscaled and not Re-mastered to a bluray format such as AVC or Mpeg. Most newer movies are close to the original footage quality. There are some like our movie Burn after Reading which was an upscale and had poor quality for Blu-ray. It depends on how much the production company wants to spend on distributions( dvd and bluray). This is one reason some of the really great movies like Saving private ryan and Gladiator(sapphire edition) took so long to be released because they had to be completely Re-mastered for High Definition. It is very cheap and easy to take a DVD and upscale it to 1080p for a bluray disc. If this is done then you don't need 50GB worth of space for such a small file size so 25GB disc is used. The sound is very easy to Re-master and does not take up as much space as one would think. DTSHD MA takes up 30 percent more space than the DTS track in most cases. There are several movies that are near full quality video on a 25gb disc but you'll notice they feature very few extras and the sound track will be a lossy (not Lossless) one. DTS HD can be marketed as "Lossless" but in some cases is still compressed. Making a high quality transfer fit on a smaller BD. Any other ?'s feel free... I love talking shop

Hrm, why wouldn't they bother having at least a 1080p master for Burn to work with? I know nothing of the Avatar thread, but the whole thing smells weird.

I'm going to take a wild guess and say the guy's just making stuff up and is not to be trusted.

[Jeff Kleist]

l....most any movie filmed pre-bluray will be upscaled and not Re-mastered to a bluray format such as AVC or Mpeg....

Right there is where everyone should stop reading, he has no clue what he's talking about, and if he truely has a job in Focus's mastering department, then they need to seriously review their hiring practices.

Maybe he's the source of the ludicrous BS that came from someone at Uni that the demand for lossless audio causes them to compromise the video, and that;s why their ancient masters and HD DVD ports didn't look up to snuff (of course, they didn't look up to snuff on HD DVD either and that was lossy )

[DenonCI]

I'm sorry, that guy is full of $hit.

Jeff,

This guy is a tool, plain and simple. Frankly he writes as if English is his second language...take that back, third language

Could be true for the HD-DVD of Traffic

That was the exact point where my eyes rolled so far back that I could see the back of my head.

[Jeff Kleist]

Who makes up they work at Focus Features? He's probably some tape monkey or off the shelf suit. Either way, I'm betting that by lunchtime someone is getting a talking to by their superior.
