From what I am reading, she is claiming that digital is the perfect way to go and see a movie right now and I agree with her.
Oh thats right...your a troll because you clearly don't read things very well or make intelligent statements. But you sure make a lot of them!

She said the image was perfect, not that it was the perfect way to see a movie...there is a difference. Perfection is almost always an unattainable situation but can be a fine goal.

quote: Tom Petrov
Also, I have yet to see 35mm be crisp and clear as digital.
I don't know...perhaps you suck at showing 35mm? Or perhaps you misinterpret film resolving more detail into thinking it is less crisp. Or you are using the current, but not historical or even 100% practice of using an inferior 2K DI as a means of judging the delivery medium. It can only deliver what it was given. Your complaint should be with the 2K DI.

quote:
Her comments having nothiing [SIC] to do with 70mm. Her comments are based on 35mm vs 2k/4k
Her comments were "digital is perfect." She also made the false comment that 4K would not bring anything to the table in her smallish theatres. By encouraging her to see images that are MUCH closer to "perfect" than what she is experiencing she could more properly evaluate her 2K pictures with respect to perfection.

quote: Tom Petrov
35mm and 2k are comparable are they not?
Comparable in the sense you can line up a list of pros and cons with their end results. The only way that 35mm wont run away with the list of pros is if you deliberately mutilate 35mm's source material...with a 2K digital intermediate. A temporary situation that, in no way, reflects on 35mm's capability. However, even this discussion is straying FAR from the discussion. My questions to Elise were to get one of understanding on why her comfort level was higher on the digital equipment over the film equipment. My only comments on digital vs film were with respect to simply wrong statements (2K digital being somehow perfect).

quote: Tom Petrov
Thats fine, but Elise is simply talking about 35mm vs Digital.
She was actually talking about her comfort level of film versus digital as well as her perception of digital's image quality. The gauge was not part of it. I brought up 70mm, not to sway the discussion there...though it seems to bother you when 70mm is held in high regard...as a means of showing how the current 2K image is FAR, FAR from perfection...note too...I also used 4K digital...something like 35mm film that is roughly 4-times greater in resolving power. Her only statement on 4K was that it would bring nothing to a theatre with a 30ish foot wide screen...I countered with that statement was false and why.

Krhm. Now this has evolved on its own... right. The fact is, there was a 4K presentation I missed (darn train scedules) that I would have wanted to see, a very rare opportunity around here. I have yet to compare 2K to 4K with my own eyes. That it makes no difference on a small screen was an opinion offered by our equipment provider who I trust in this matter above anyone else. The guy has decades of experience on film and he was to my knowledge the first one to sell digital in the coutry. I do think he lurks around here sometimes, too.

One thing that Steve said, about the rebooting habit. I'm on my second smart phone at the moment, and I never rebooted my old ones, ever. But these ones, sometimes I have to. As they say, they're more tiny computers than phones...

My point here was indeed digital versus film in general, and I do leave out of the equation the 70mm because I have no experience with it, having never even seen it. Would have to go out of the country for that... I will have to, soon. So that's entirely my shortcoming and affects my view a lot.

And no [Big Grin] I don't definitely know if Any part would be available in a few hours but I have been given to understand that this is the case. I'm crossing my fingers on not having to be proven wrong on this.

To close, I like to point out to Steve that the fact I Can call for help and get it (there is a certain solidarity in the industry here, everyone knows each other are willing to help out if they can. Scrathing each others' backs as the proverb goes) does not mean that I do, every time. I can and will when I run into a wall, that's for sure, but not before I've tried to find the door first and tried every key there is.

Uih. Back to work. And hoping that our luck holds and everything always runs as smooth as now. Oh I know it won't... but one can always hope.

Steve, before you get too involved in your arguments for 35mm, remember many theaters have 35mm equipment in poor condition. Image stability alone will kill resolution. Then again burned lenses or even dirty optics, fake port windows, too much heat on the film and discolored reflectors will murder the end quality too...among other things.

I've found there are VERY FEW theaters that actually do everything right to show off 35mm's full potential. With the edge enhancement and other digital trickery going on, to the layman digital APPEARS to be sharper to them.

Its a legitimate argument on both sides. In the end though, its the public that we have to impress to keep them coming back and not sticking to blu-rays at home.

Steve is absolutely correct that 35mm as a format can outperform any flavor of digital right now, but lets do a reality check. Right now, as in today, when we take into account the foolish 2K DIs, the SHITTY labwork being done at Deluxe (they have gotten worse somehow), the candy counter/manager projectionist and everything else that goes into the pot...digital is better in the end. Nobody (with rare exception) will ever see how good 35mm CAN look any more.

Then again there are a number of installers out there that don't do proper convergence, boresight and color calibration with digital, so maybe I shouldn't be giving digital quite so much credit. Those sort of things will kill a digital presentation's potential quality too, its just not as noticeable to the layman.

Brad...I wasn't going for a Digital/Film technicalities...at all...just the understanding of the "comfort level." The potential of 35mm, 70mm and digital 4K was to prove the IMPERFECT 2K...that is it.

I think Elise explained herself quite well.

Note too, I believe that the 2K DI is a temporary thing and that 4K DIs will be the norm before too long...especially once more theatres are 4K capable and the cost/time associated with 4K comes down to acceptable levels. As such, even 35mm film will benefit quite a bit.

Just to step back to this subject:

quote: Brad Miller
If you have a full container DCP and you show scope, you are cropping off the top and bottom of the "full container" image to create a 2.39 scope image. (In a scope DCP, this top and bottom area is black.)

If you have a full container DCP and you show flat, you are cropping off the sides of the "full container" image to create a 1.85 flat image. (In a flat DCP, the sides are black.)

If you run a scope movie in flat, you then see the black bars AND you still crop off the sides. In other words, flat doesn't use the entire width of the chip and scope doesn't use the entire height.

At work our servers have 2 setting for flat (4 if you count in 2D and 3D)

There is both a 1920 and 2045 setting for flat on the server and projector. What are the differences using the different setting?

The only reason you should have 1920 settings still is if you have older series 1 projectors without full-frame triple flash capability. Those that have EFIB boards will only be able to have 1920 x 804 scope and 1920 x 1035 flat images at triple flash rates. Series 1 projectors with FFIB boards can do full frame triple flash.

In short, you should only have the type your projector NEEDs, the other shouldn't be used. The exception being...if have a mix within a complex and you get a 1920x movie and need to play that in your 2048 theatre...then you should use the 1920 settings (presuming they are properly calibrated) so the projector will properly size it on screen.

1920 and 2048 (does yours really say 5?) are horizontal lines of resolution.

You want to use the latter as it is ~10% higher res. 1920 is the same resolution as HDTV.

Using my wonderful Sony, I screened Harry Potter this afternoon after stopping the showing of something flat that we are dropping, finally. Used the end template to get everything reset.

Started it up, and got the scope inside the flat image again.

I built the show, as usual, and everything else works... masking changes, etc. After manually selecting 2D scope for 3D, it looks fine, for digital.

Did you have probs injesting HP7.1 in that Sony-Baloney unit where you had to do a cold boot with the HDD all cabled up and on to continue the injest?

Sounded like you played "Feature-HP7.1" off the show listing which doesn't have any cues to set your maskings at first until you did the playlist.

Do you do the build the list with the "feature title"first, then add the FEATURE cue with an :02 cue offset then Credits with the offset times?

I went back to the scene of the crime this week to see if I could handle the new "projection" going forward. It once again looked awful. [puke] I could not get passed it. What they have done to the theatre has ruined it. And it's an insult to the rest of you who *do* do it right. It's really too bad. [Frown]

The most rediculous part (aside from the whole thing) is it's bad enough the scope image creates blank screen black bars at the tops and bottoms of the flat-masked screen, but when a flat trailer plays within this "scope programming", you also get blank screen bars on the sides too! Basically, it's a small flat box inside of a flat-masked screen. It's an insult to paying customers and a tragedy to the industry.

I sent an email to Cinemark to complain, and to suggest a technician come out to look at and fix this installation, but I'll bet you my email was just deleted without being read.

As much as I love the theatre, unfortunately I will not be back. They've really ruined it. [Frown]

And what the hell, I'll name names. This is the CENTURY 24 twin theatre in San Jose, CA. Once run with pride by the Syufy's, turned into a complete joke by Cinemark. [thumbsdown]

I build the feature first. Add the title, then feature cue which is 0 00 00. Then, add the credit cue, name it, and save it.

Then, build the entire show. First thing is 2D to 3D scope/flat.

Only my 220's have this strange mask problem. The 320, other than not liking trail mixes, has not acted up one time, and is programmed just like the 220's are.

No, I didnt have to do the hard-start. I give the projector a little time to see the trail mix, or the multiple copies of the feature, and open the drop down menu 2-3 times, and the thing works.

My tech told me that he was fielding lots of calls about theatres loading the wrong version of HP on their projectors.

I simply read the sheet and decided what to run.

For Eric, the theatres cant help with flat features being advertised on a Scope screen. It's the way they are distributed by the studios. There's always been black sides on flat feature trailers presented in scope. I see them every day. I doubt the studios are going to change because somebody doesent like seeing a small picture on the big screen.

The same thing can be said about scope features advertised with a flat film. My people constantly try to adjust the framing on scope on flat trailers. They've tried to say that I built the things out of frame, too. Thats never happened.

Eric,

If they don't listen to direct communication, put your comments out there for all to see, and maybe public embarrassment will help. At the least, others will know to watch for the problem, and maybe they'll complain as well, and the problem may eventually get fixed.

We created the Reader Comments feature for just such a purpose. Here's the comments page for the Century 24 on Winchester Blvd. in San Jose:

Well there you go- it's a twinned dome theater, which means it hasn't been "run with pride" since it was twinned. I would like to personally punch in the face the people responsible for the twinning of these dome theaters.

Pride indeed!

I was around for this era.

It was as bad as it sounds and then some; a straight wall disecting two sides of a round stadium building. The left projector on one side of the wall, the right the same, seats still pointed at the middle of the room.

Funny, they had no problem getting first run films and a lot of the audience seemed too stupid to go elsewhere

If you guys think it was silly after it was twinned, you should see it now with the shitty "digital projection"! What a f'ing joke! [puke]
