Yes, they claim their "profound sound" is "mixed". No, I don't have an explanation, you may want to show them your ticket and ask them what that does mean.

If your 2D film was shown with 3D lenses, it was not shown in 4K and the inevitable convergence drift would affect sharpness.

Would the studios allow a cinema chain to tamper with their sound mixes? I doubt it. If I asked anyone at the cinema I doubt they would have a clue about what profound sound is. It did not sound anything special or different to me. Mind you, The Imposter is not the best film to judge image or sound but this does not justify the poor exhibition standards.

What are you talking about? Theatres have been "tampering" with sound since they got sound! Too high, too low, playing mono movies in stereo, stereo movies without left/right, fake noise reduction, making their own surrounds, no center channel but only surrounds, bad EQ, bad speakers, bad acoustics...good grief!

True, but what I meant is allowing a cinema chain to produce their own sound mix of a movie, a bit like what IMAX does. I am curious as to what profound sound is. Probably it is as good as advertising 4K projection and screening flat films through 3-D polarisers.

I would ask the company. They are advertising it, there must be something behind. Otherwise it would be misleading advertising, wouldn't you think?

I have asked them about the polarizers, if they reply I will ask them about the profound sound.

The same company also has Barco 2K projectors in their larger 3D screens, yet still advertised as 2K.

It would be worth referring the situation to the Advertising Standards Authority to get them to correct their publicity. (on a less serious note their competitor who claims to be "fanatical about film" could also be referred)

Adversing 4K projection implies that 4K content will be shown despite a lot (most?) of the current releases being 2K

Alternatively a CP750 connected to the existing amplifiers and speakers, another one for the ASA I think.

It is bad enough to show flat films on a silver screen, I know no one cares about curtains anymore, but no masking!

A lot of the screen will have masking, it was disconnected with the move to digital (looks particularly good when showing 2.39:1 content on a 1.85:1 shaped screen)

quote: Carsten Kurz
I don't know, the whole 3D thing is not actually covered by DCI, and quite sure all units have been under CTP in 2D modes only.

My understanding is that Sony projectors, with 3D lenses, are not DCI compliant. The specification requires a 2048:1080 image area for 2D content (with lens changes being automated). Having said that a lot of the AAM installs (for the UK Film Council funded network) used scaling, rather than adjust the zoom on the lens.

From the DCI spec:

quote:
8.2.2.4. Single Lens
The projection system is required to provide either a single lens solution or an
unattended changeover if more than one lens is required.
...
8.2.2.6. Pixel Count
The sampling structure of the displayed picture array (pixel count of the projector) is
required to be equal to or greater than that of the specified image containers (either
4096 x 2160 or 2048 x 1080).
8.2.2.7. Spatial Resolution Conversion
The projector is required to display either a native resolution of 4096x2160 or
2048x1080. If the projector's native resolution is 4096x2160, and the incoming spatial
resolution of the content is 2048x1080, then the projection system is required to perform
the up-conversion of 2048x1080 content to 4096x2160. All spatial conversions are
required to be done at an exact ratio of 2:1 in each axis, i.e., a projector with a horizontal
pixel count of slightly higher than the image container is required to not convert the
projected image beyond the image container to fill the array, nor is an image to be
converted to something less than the 4096x2160 or 2048x1080 image container size.
Should electronic image resizing or scaling be used to support a constant height
projection or constant width projection theater environment, then it is required that the
image resizing or scaling does not introduce visible image artifacts. It is intended that the
projector project the full horizontal pixel count or the full vertical pixel count of the image
container.
...
8.3.3.3. Screen Characteristics
The screen is required to be non-specular and equally reflective over the entire visible
spectrum. The screen is required to have variable black masking, adjustable to tightly
frame the projected image. This is required to minimally include 1.85:1 or 2.39:1 image
formats. Masking for other formats is optional.
