1280 x 1024 video resolution

[g_shocker182]

This was the resolution used by many of the first digitally filmed movies (Attack of the Clones, Oceans Eleven) . Being it high quality, I was wondering if anyone knew where I could get sample clip to see what it looks like on a home computer.

steal a digital projector hard disc?

[funkguy4]

I doubt it 1280 x 1024. Remember, it was widescreen. I would think it was 1280 x 960 or less......

[rallynavvie]

It was filmed 1280x1024 and then cropped for widescreen. That's what many cinematographers do these days rather than worrying about filming in widescreen. If you have the resources it's easier to get what you want cut from a larger source rather than worry about getting it all right on the first shot. I don't know why it would have to be 1280x960 as that's 4:3 res, unless 1280x1024 is PAL 4:3?

[funkguy4]

My bad. I meant 1280 x 720.

[g_shocker182]

are there any samples of this on the net?

I dunno
Go find out.

[flaninacupboard]

there was a sample from matrix reloaded that was 1024Xsomething. in some quicktime format or other. looked quite nice, but needs a decent machine to decode it.

Yeah, QuickTime 6 has become MPEG-4 based. Needs the same kind of computer as XviD or DivX.

100MB...thank god for cable

[funkguy4]

Why 1280x1024 though? That's a weird ratio.....1280x960 would suit better.

[BJ_M]

not sure where you get that res either, we shoot on 1080p24 or 30 or 1080i60 (and sometimes 720p24or 30) .. here are the HD resolutions:



1035i 1920x1035 1125 lines
480i 720x480 525 lines
480p 720x480 525 lines
625p 720x575 625 lines
720p 1280x720 750 lines
1080i 1920x1080 1125 lines (sports)
1080p 1920x1080 1125 lines (cgi)
24p 1920x1080 1125 lines (film)

also d-cinema will be 2:1 aspect ratio 4096 x 2048 (or ratio thereof)

BJ_M, since you're rich, can you send me a 1080p HDTV? PLeeez....I'll pay shipping

sure -- np

msg me where you want a sample sent ..

[funkguy4]

No no, I don't want a sample of video, I want a real TV. The kinda that plugs into the wall. The expensive one.

[BJ_M]

oh yea -- ok sure .. how about a 42" plasma ?

i have one that a forklift truck bumped and cracked the front glass -- you can have real cheap... just a little problem that all the plasma leaked out .. i got two of those in fact (other one is burned in image)..

[Conquest10]

how much would one of those go for?

[BJ_M]

new -- these were $13,000 each

[Conquest10]

no, i mean damaged.

[funkguy4]

no, i mean damaged.

What, are you going to refill the plasma and replaced the glass on both of them?

[Conquest10]

What, are you going to refill the plasma and replaced the glass on both of them?

yes.

[g_shocker182]

BJ_M, how does your plasma tv work? what is this "plasma" i hear of?

[EddyH]

Yep, the most common (read: cheapest) of the DLP resolutions is 1280x1024 (if you wanna get swanky, there's also a quad version at 2560x2048... mamma mia, my digital camera doesnt go that high!). Heard of it in a few other places before.. such as a movie report where people were comparing a 35mm version seen in one cinema with a "low" rez DLP version seen in another - common complaint was that though it was far less grainy and scratch free, it was noticably pixelated and fine details got lost So high-rez as it is compared to VCD or DVD, it's *still* not good enough for a true cinema experience! Blu-ray and HDTV may yet be improved upon then)

Very odd that they chose that rez, unless it's the natural shape of 35mm film (like I know? ) - you won't be getting anything even close to square pixels, probably more like 2:1 width to height, which makes a whole lot less sense on the silver screen than when capturing from a VHS.
Personally I would have thought celluloid to be at least 4:3 (like, 1280x960 if you want the square pixels and similar rez), the old Academy ratio that lead to the 4:3 TV, or maybe 3:2 (like the standard 6"x4" photograph..), so approx 1280x864. Suiting it for the usual crop of widescreen films makes it seem like an even odder choice: Surely a middle ground of 1600x900 would have been wise as a minimum starting point?

(mmm... a 2000-inch TV... 16x9... with 3200 pixel horizontal resolution and 1800 lines... that would be sweet... just what you want when de niro's mole is measured in metres... thats like an effective dot count similar to what an old 300dpi printer would get on the whole of a standard size page)

who wants to test a 352x240 DLP now?

[BJ_M]

EddyH - not trying to knock your post but ...



1. the cheapest lowest resolution DLP is SVGA (800 x 600) (like the Toshiba TDP-MT5U for example) ..

2. no such thing as a 'quad' version DLP ... there are many different DLP chips made by now at least two companies (even some of the people that make them are on this forum).
There is the new 2k black d-cinema chip if that is what you mean ...

3. There is no pixel screen door effect on d-cinema DLP projection up to 40ish feet using conventional 1280 chips .. and with 2k chips we are blowing onto 60foot screens ... It is not a "low res" image , unless someone just stuck a little DLP up on the screen with a dvd or something .. dont know what that is supposed to show .
Currently digital cinema is mostly 24p projection (1920x 1080) , but remember that d-cinema projectors use anamorphic lens just like the film projectors (same lens justt about in fact) .. so im not sure where you get those sizes from..


4. We use higher than "standard" HDTV quality (and Blu ray) already ..

5. the official D-cinema aspect ratio is 2:1 and will be 4k resolution or ratio thereof

No sweat BJ_M, I don't profess to be an expert (like you look to be ), just repeating what little i've heard and speculating / dreaming.

thoughts...
1/ Who would want to watch a DLP film at 800x600? I'd sooner just play a 720x576 DVD and buy my popcorn and drink at a quarter the price..

2/ OK, I didn't know what it was, just blowing specs out my ass really. I just knew that 1280x1024 was supposed to be a first-gen chip and low rez compared to what was supposed to be coming.. talk of 2048-by-something and 2560x2048 projectors 'in the near future'. Seemed pretty natural that it would just be doubling the rez in both directions to be easily compatible with the old material / new material with old DLPs.

3/ wasn't any mention of the screen-door effect like you might see on a computer projector in a college lecture theatre. just that the picture occasionally looked 'pixelated'. Like a super sharp line-graphics scene might appear on a PAL TV set It was a review of an anime screening after all.
24p at 1920x1080 = it's an adaption of HDTV? (triple scanning a 72p picture?).
Didn't know if it was using the wide-field anamorphic lens, assumed it was maybe using real wide pixels... like the red/green/blue elements were all no more than twice as high as they are wide, and striped horizontally, so each 'full' pixel was at least 3:2 size. 1.25 x 1.5 = roughly a 1.85:1 ratio...

Where the dimension figures came from? Simple. My 2000" TV size was based on a Wierd Al song

4/ um... yeah... i was meaning for home systems, not cinema.. spotted that 2560x2048 was higher than any HDTV standard

5/ when you say those D-cinema things.. you mean..
* a picture "physically" (it can be said to only virtually exist, as it is just changing illumination of a surface) twice as wide as it is high, sitting between the 2.35 and 1.85 ratios
* composed of approx 4000 pixels horizontally, and a suitably matching amount vertically
???

cheers

I looked at the flash overview. Wow. 35 trillion color-projection tv. Where can I see real DLP chips? Wheres the market for DLP chips (theatre or home)?

[BJ_M]

a lot of the 800x600 dlp projectors are pretty cheap .. thats the same resolution used in many rear projction tv's .. not meant for for large screens ..


dlp projection is for home and theater .. prices range from $1000 to $160,000

animation film would not be scanned but the source file would be used to make a digital file (QuBit or mpeg2 or other) @ 1080p resolution square pixel .. (sometimes also 720p), playback would be by a dedicated hardware server.
Film would be scanned (if not existing digitally) at min. 2k resolution (as mentioned in a prev. post - there is a cheap way to do this and a expensive way) or higher, color corrected and resized to 720p or 1080p ....
These files are played at 24 (mostly) or 30fps (a lot of our stuff).. but there is no pull down involved.

yea --- i could understand pixelization happening as you describe .. i have seen it myself ... they just used compresed material that was done by people who didn't stick around dvdrhelp.com and learn --and/or poor delivery media .

[EddyH]

Well as far as I can tell it was a film original... used painted cels mostly anyway, with some CG effects, so it was probably photographed digitally and then mucked about with on a computer, rather than 100% digital. Not sure what happened from there on in. Don't think it was compression artifacts though - more like the stepping you might see from printing out a fixed-rez picture just a little too large. Think of how big the pixels are going to be at 1280x1024 on a projected movie screen - and how they can still appear blocky on a small-ish LCD that doesn't take up a large amount of your field of vision..

Still, a home video with that much rez would be sweet..

[BJ_M]

what you saw is aliasing and can be a problem ..

there ways to reduce this and are used in good d-cinema theaters .. i guess they were not at that one ...

it starts at the conversion stage but as a stop gap measure - the projector can be very slightly de-focused or use 2 projectors set up 1 or 2 pixels off from each other...

[EddyH]

you mean the kind of 'motion blur' trickery i use to reduce interlace flickering on my VCD menu screens?

thats... just... cheeky!
