I went to a cinema last night that I hadn't been to before, to see Ocean's 13. We sat about half way up the theatre, so not too close. Both of us commented that the picture didn't look *quite* in focus, although that didn't seem to quite cover it. When the picture stood still though, it was pin sharp. During the advert session, they mentioned that some sporting event or other, was going to be covered live via satellite, which got me thinking that this must be an *electronic* cinema, using DLP projectors. It then occured to me that what we were seeing as being 'out of focus' might actually be motion blur, typical of digital display technology. With this in mind, when I looked even closer, it seemed to me that the picture was not evenly illuminated either - a bit like I see on this widescreen LCD monitor that I'm using here. During the main presentation, a film-stock 'scratch' appeared at the left side of the screen. However, it went on for a long time, and was absolutely dead straight, although it did jump back and forth a bit, but very 'precisely'. Also, it's colour seemed to change with the surrounding content, so if that was black, the 'scratch' would be white, and so on, so I then got to thinking that this might be an error on a line of mirrors on the DLP chip. As we left the cinema, I took a look up at the booth window, as best I could, and there didn't seem to be any film looping around the ceiling that I could see.

So, does anyone out there work on these DLP projectors - either commercial or domestic ? *Was* it one of them that was showing this film ? Are these DLP chips slow enough that you can see motion blur ? Was that 'scratch' typical of a DLP chip problem ? ( it wasn't there at the beginning, and it went away before the end )

Sorry it's a bit OT, but it seemed like an interesting subject, with a potential repair-related angle, and we sometimes have some good discussions on here about such things.

Recently helped present the premier of Spiderman 3 at a large convention. The projector was--I believe--LCD, the screen, about 30'x50' (or whatever the correct ratio would be). The film looked great in the Aladdin Performance Theater (Vegas). I don't have a 'film' reference to compare.

I have noticed that sharpness in movie presentation has suffered over the last decade or so. I recall watching Titanic at my local multiplex and being very disappointed at what looked like focus issues, only to see the presentation sharpen up for static scenes.

I think it's just an indication that the art still requires an effort to suspend disbelief. For some reason, I've never experienced an IMAX presentation. I'm afraid I'd be disappointed. Despite all the hype about hi-def TV, I'm still not all that impressed so far.

YMMV

That sounds like the same thing on the Titanic show,Jak. I've seen IMAX film presentations, and they are stunning. We've also got some HD transmissions on sat here now and, leaving aside the motion artifacts from the actual display technology, I think that they look pretty good,but I'm not sure that's good enough for me to want to put my hand in my pocket to pay the extra subscription.

I have an IMAX here in Nashville. I'll have to brave the crowds some time. I've seen hi-def and not been 'that' impressed. OTOH, I'm comparing NTSC, so your mileage would be different.

Is Alladin's refurb finished yet ? It was still in progress when I was there last year. Are you based in Vegas ?

The casino has been sold to Planet Hollywood, and is under expansion, but the theater--though attached--is still Aladdin. Very nice facility with VDOSC sound and extensive lighting rig. Despite the quality of the in-house audio, the movie people insisted on bringing their own, consisting of big bass bins with old 4' square JBL constant-directivity horns with a smaller JBL horn mounted coaxially for high end. I think they were concerned that they wouldn't be able to match the surround gear they brought with the house system.

I was working a convention in Vegas. Spidey was part of the entertainment, along with Hall & Oates, Jay Leno and the Blue Man Group.
