Re: Fake 4k Blu-ray discs from Sony this summer
What a fucking gimmick. If any of you buy these titles, you should be slapped.
In their current encodes as of right now:
The Amazing Spider-Man: 25 mbps.
Battle: Los Angeles: 22 mbps.
The Karate Kid: 23 mbps.
The Other Guys: 26 mbps.
Taxi Driver: 24 mbps.
Total Recall: 16 mbps.
Once all is said and done, these Sony titles average anywhere from 25GB (Total Recall) to 37GB (The Amazing Spider-Man) at the most in their current encodes (including audio and video). Even in their current encodes, some of them are reference discs.
Isn't the reason most video encodes on Blu-ray don't go over 40 mpbs is due to the fact that a lot of players' hardware/firmware can't handle it? When you look at the stats, the only discs that come close to reaching that bitrate are IMAX documentaries... and they're right at 40 mbps. A two-hour movie with an average 40 mbps bitrate and one or two uncompressed audio tracks will throw you close to that max capacity size. With that in mind, most of these titles won't eclipse 30 mbps, especially when including uncompressed audio tracks into the mix.
... and it all depends on the source material. A lot of these films were shot and-or mastered in 2K (I'm looking right at you Total Recall). A massive bitrate increase isn't going to significantly improve most, if not all, of these titles based upon their source materials' condition.
Throw your average Blu-ray player now into the mix and the benefit is nil.

Gees Sony, at least toss Easy A in there and give me some more Emma Stone to look at!

Re: Fake 4k Blu-ray discs from Sony this summer
if this is the new Superbit - it'd make sense to encode/remix the films to 96kHz and 7.1 surround sound too ... but hey Sony are a bit clueless and not that market savvy
'Leon the Professional' is 96kHz. The German DVD of 'The Fifth Element' has DTS-ES 6.1 matrixed sound.

The 4K source is that of a glorified up convert.

Re: Fake 4k Blu-ray discs from Sony this summer
The film was actually shot on both film (Super 35 using the Arriflex 35-III) and in both digital 2K (Weisscam HS-2) and 5K (Red Epic), but that digital intermediate at the end of the day is still 2K.

I found an interview where the VFX are mentioned as being 2K, but not about the DI:

POST: Where did you do the post?
WISEMAN: “I did my director’s cut at my offices in Santa Monica, and then we moved to the Sony lot and expanded the crew. They have a great team there, and it’s great to have the mix next door, and the color timing at Colorworks, and I can do all the 2K effects reviews with the Skype sessions in the screening rooms. That’s been a great process for me, since on Die Hard this sort of system wasn’t even set up yet.
“So I can work with Dneg in London, look at the 2K file, and then draw on a tablet on the 2K image in full res — and it’s so great to be able to draw in realtime.

Re: Fake 4k Blu-ray discs from Sony this summer
All of those movies listed above could still comfortablly be encode at double the *video* bitrate and still be within the specs. These days, with 7.1 encodes and 96 khz, audio could end up taking more disc space than the video encode!
The purpose of these high-bitrate encodes should be to maximize the total video bitrate, get that extra 10% out of the presentation. And, I can guarantee that those movies will look better on very large screens, when encoded at 40 mbits/sec video bitrate. That is, if all other things are the equal when compared to the current encodes, eg, No added DNR, EE, or color tweaking is done.

No way would 96khz/7.1 take up more space than video. Lossless 5.1 tracks are less than 4Mbps. Double the sampling rate and spread the surround audio to 2 more channels, and it should still be at or under 10Mbps. Even Akira's 192khz track is about 14Mbps.

I meant that the 7.1 / 96 audio track, when *combined* with all the other audio mixes on some releases could (4 or 5 dubs, 5.1, DTS, etc) could easilly double the encode size (and, thereby, wind up effectively reducing the average video bitrate by as much as ~ 15 to 20 mbit).

So, its on to 4K? We haven't even got a release of The Abyss and True Lies, in an anamorphic transfer, but we're doing 4K?

Cameron may kick the bucket before we ever see those in 1080p.

Eh, just go for the Spain or Germany release. I've lost all hope for a good US one. And if we do, it'll be thrown to Olive or some other company that'll give us a half-assed barebones release.

got the German version, the image seems a tad opaque/guazy and I'd think that it could be improved.

Re: Fake 4k Blu-ray discs from Sony this summer
Then why are all the studios still making digital intermediates at 2K? The number of films that have digital intermediates made per year at 4K can barely fit on two hands.
I'm sure more older films are getting 4K remasters than actual new films getting 4K masters out the door.

Re: Fake 4k Blu-ray discs from Sony this summer
Someone please clarify for me. Sony is launching 4K Ultra HD Televisions but there is no 4K Ultra HD content right? No broadcast, no disc media. What are you supposed to watch with these new TV's?

But seriously, there was something in the press release implying that actual 4K titles would be distributed digitally.
