Why do movies look sharper on my laptop?1080p LCD Vs2k in cinema
Posted 29 December 2012 - 09:08 AM
I also go to a few different cinemas and have seen lots of different movies. Without doing too much research into the specifics I assume they're mostly showing 2k digital projections nowadays.
I've yet to see a film at the cinema which looks as sharp and detailed as the image on my laptop. Even a 720p video on my laptop seems sharper than what I get at the cinema.
This isn't just one local cinema with a bad screen, it's several screens across several cinemas.
What's happneing? Is it that the larger cinema screen _seems_ less detailed because it's so large I can see the lack of fine detail?
Is it the projector blurring the image because of optical impoerfections or tiny vobrations?

One of my beefs with digital projection is that the resolution just isn't there. I remember seeing movies as a kid, and the films were like giant murals. Nowadays it's not quite the same, and digital projection still has a way to go.
As an aside I remember the first prototype digital "LASER" projector. The thing was the size of an old 65mm Camera used during the 40s, and required tons of water to cool it. The image it gave wasn't all the impressive. Today's digital projection, to me at least, looks okay, but where the image is nice and clear I don't get a sense that I'm seeing the same level of detail from films I grew up with.

With all the digital everywhere I don't think I've been as impressed for a while, I'm sure it'll get better, I just think it's been a little rushed into.

A point of order about DCI and 35mm projection.
The resolution of digital cinema is, by the commonest measures, better than what most film could do. It is effectively impossible, taking into account the four generations of the interpositive/internegative technique, for 35mm answer prints to display more than 2K, or more usually 1.2K to 1.5K, of real image detail, much less if a fast camera stock is used. The idea that 2K DCI isn't as sharp as 35 is simply mistaken, at least on a per-frame basis.
The impression of sharpness in film projection may be improved by the visibility of grain, which can have detail at considerably higher spatial frequencies than the actual image. As well as providing higher frequency detail per frame, the shifting grain pattern of each frame can arguably produce an impression of higher overall resolution than actually exists, although this is somewhat subjective and affected by flicker.
I am not concerned that DCI generally gives us less than 35mm projection. It looks different because it doesn't flicker, is generally brighter (certainly very much brighter for the same lamp power), and is extremely stable, but it's difficult to cast any of those things as problems. Most of the problems that do exist are human factors concerning care and maintenance which affect film projection in much the same way.

Now some people prefer projection of movies versus seeing them directly on a computer screen, the "texture" of a projected image plus the viewing size and distance is more "classical" for cinema viewing.

In the last three or so years a good run in the mill video card today, one with say 1 or 2 gigs of RAM can give you incredible resolution. I'm using a Dell 30" monitor right now, and can blow up DVD images to full motion without a hint of loss.
Streaming is another story. Right now I've got something streaming from Amazon (an old Brit TV series), and resolution is only hampered by the speed of my DSL. If I blow it up to full screen it gets slightly pixelated but only because the rest of the data hasn't come down the pipe to my video card. With a faster line, say a cable modem, that image would be just like regular TV.
Are you thinking of theatre size projection verse a monitor, maybe?

This is actually likely to become a pretty significant problem in the near future, with people demanding better and better streaming media, and assuming the speed of the link they have with the telephone exchange is something that we can all have simultaneously.
It's certainly true that, colorimetry notwithstanding, people can see amazing levels of sharpness on very everyday 24" desktop displays. It's not hard to make a digital cinema image look that good, but it does require someone to be watching focus and alignment, which is a level of care that is not available in most multiplexes.

I've not seen the film yet but I'm going in a few hours to VUE in Cardiff. I hope but very much doubt that's the version I get to see.
I've found several news articles that the cinema does have 4K on at least one of their screens, but they can;t think it very important because they don't give nay nformation at all about it on their own site.
