I find all this quite interesting. Keep rambling.

My video processor has numerous options for tailoring it's video source inputs. It's got the option to select film or video, and then goes down further for selecting frame rates. I don't have a clue when I should should select either format or the different frame rates.

Frankly, with that kind of consideration, I'm surprised they're being dumb enough to shoot in 1920x1800. Is there simply not the storage capacity/bandwidth to deal with shooting higher?


74.6 megabytes of data per second (at 24fps, 4:2:2 colour space) at 1920x1080 and that's with no audio. Not sure what a natural shoot-to-keep ratio for feature films is (never worked on one), but for documentaries it's easily 10 to 1, not counting B-roll.

Assuming a s-t-k of 20:1 for a film, that's about 8 terabytes of footage.

Plus, try to find a CCD that's natively higher in resolution than 1920x1080.

Then doing post/CG additions at insane resolutions turns a render farm into Animal Farm.

Not sure exactly what the answer is, probably a combination of all these.

Well, sounds like they're not really ready to go digital yet, then, are they?

Depends, most people can't even tell when they're stretching a 4:3 program into 16:9... I'd say probably a further 25% can't tell a quality difference between VHS and DVD, 95% of people don't see macroblock artifacts in DVD video and 100% of people in sports production can't see a difference between lower-field dominant, 4:1:1 DV footage and upper-field dominant, 4:2:2 Beta footage.

Most people don't notice quality. That's why country albums sell.

Yeah, I'm surprised it was only shot in 1080 high-def and not ultra high-def, especially when it was then shown on IMAX screens. Maybe I missed the outcry when Superman Returns was playing on those screens, but it seems like if it could look decent on that large of a screen, it can look good on a home system.

Besides which, when I watch high-def programming, it's usually the shows shot digitally that make me stare, not the films. If Superman Returns has a sucky picture, I'd blame the filmmakers before I blamed the technology.

I dont agree with this at all, while not the best looking HD DVD the picture quality was great. Just got the PS3 and rented Black Hawk Down from Netflix,from what I hear one of the best Blu-Ray yet.




Don't get me wrong. I didn't say the movie was bad, just not that much better than SD and not good enough to warrant the expense of Homedad buying it twice.

And just out of curiosity, how are you getting True Dolby? Do you have HDMI 1.2, or are you running 6 channel analogue?




I have both HDMI and analogue hooked up but I use HDMI to my Denon 4306 just because its easy.Oh and I think we a focused alot on the video quality,but the sound is so much better also. DD 5.1 has nothing on DD+ 5.1 or Dolby TrueHD 5.1. Most of these titles sound is 1.5 mbps.I am no expert by far but I know when somthing sounds good and I might double dip on a dvd for better sound to.

Yet. And yes, I realize film has the equivalent of a much greater resolution than digital so far, but I didn't think that would matter on a home theater. I'm not using an analog projector. I have a digital television. You'd think something shot digitally at the resolution my TV is capable of outputting would make more sense than film resized and converted.

There's far, far more involved in a good looking picture than resolution. In fact SMPTE recently had a test screening comparing a 2K digital projector to a 4K digital projector. It was the consensus of the room that the two were very comparable with no clear winner. (The screeners didn't know which they were seeing). In that case it was mostly the contrast which made the 2K image look as good as the 4K one. Contrast and color bit depth are as important (if not even more so) than pure resolution.

These guys are trying 4K capture.

FYI...I've currently run into an issue using After Effects at the office. Aparently I'm the first person to call and complain about this. I can't render out files larger than 4096x4096 in any file format higher than 8-bit. I need to render some 6K and 8K cineon files. After three days on the phone with Adobe, their answer to me was "render out a a lower resolution or buy a Mac.". Nice. We'll be contacting the project manager tomorrow. Grrrrr...

I guess my point there was that we're scanning and manipulating data at 8K. Hehehehehe...
