I know Max is pulling my leg now. Max wouldn't lower himself to associate himself with a digital medium. I honestly believe Max uses film to record family scrapbook material in addition to movie projects. Max is the ultimate purist and for that, I admire him. I love film but even I don't have a problem with DI or telecines. Sometimes I think it would be fun to actually cut on film.

Oh dear, here we go again.

There is nothing particualrly wrong with the "Digital" part of any modern system.

Whether you are a film purist or not, unless you are Steven Spielberg, Digital systems are the only game in town, and have been for some years.

The issue is always the analog part, right at the front end, whether we are talking about CMOS or CCD sensors, or film scanners.

Film is simply a much better analog capture medium than silicon.

Once the film emulsion has done all the hard work of taming real world extremes of brightness (which are far greater than most people appreciate), a silicon-based ANALOG sensor has a half decent chance of extracting a signal that can fit through the relatively narrow dynamic range of current generation Digital Post Production equipment.

Think of it as just another layer of signal processing.

No amount of digital jiggery-pokery AFTER the sensor has "sow's eared" an image is ever going to turn it into the silk purse your customers were expecting. You might be able to produce better grades of Rayon, but that's all.

If your budget can't afford this extra layer, well fine, add it to the list of other things that your project's budget will not support.

I agree that film ACQUISITION is the biggest deal in terms of image quality. But then again, you will lose something by using inferior sensors to capture even a film image. I know that the look of projected 8/16mm film is so much nicer than the look of telecined footage.

 

Maybe the most significant thing RED could provide is not to ACQUIRE images but to give a better TRANSFER medium as their sensor seems to have more DR than other sensors. I know this is blasphemy to RED users but actually may be a good idea.

I think you'll find that most people have realized by now that RED has LESS dynamic range than other digital cameras, like the Genesis or F23 for instance.

 

But for filmscanning dynamic range can be extended by scanning each frame twice, at different intensities: one to preserve the shadows and one for the highlights. The Arriscan (which has the same chip as the D21) does this for instance.

Ahh, but I thought RED was touting 11 1/3 stops? Is this true or a lie? Hyperbole?

Everyone's tests show much less, around 8 or 9 useable stops in a real-world scenario. I tend not to believe company specs in general, especially if they have a tendency towards hyperbole already.

It is widely believed that the Red camera has high dynamic range and high resolution compared with cameras costing ten times as much and that it has raw recording, for some value of "raw" that has meaning beyond "we make you do half the job on equipment you provide".

 

It doesn't actually have any of these things, but it's still widely believed to.

 

This, more than anything else, guides my reaction to the thing. The people who make it are arrogant blaggards who bask in the glory of accomplishments they could not be bothered to actually pursue.

I love the way you word things, Phil. You are so articulate.

I wouldn't pay any attention to anyones claims when tables and statistics are concerned if I were you. I'm strictly a let me see for myself and I'll know what my judgement is. That's like you claiming I'm in the top .5 percent of the population because I can write assembly language. Unless there's a large enough sample and very controlled circumstances which are acknowleged for each test, just another unsubstantiated claim.

 

People can stand on both sides with all the charts and graphs they want. I am quite capable of deciding for myself as I'm sure all of you are. Buy or rent whatever you wish and make up your own minds. Learn to see what you can make them do in your hands.

 

I've spent enough time with various formats and I have my own ideas of how I can push a certain stock or how I'd like to see a particular scene blocked for interesting but effective coverage. None of that came out of an operators manual.

 

I picked up a Red in January and still have less than six months experience with it. So far I've had no technical issues at all. I'm aware some colleagues have had some problems and since I wasn't there personally I won't comment either way. Certainly first hand experience will give me the same direct knowledge I've always relied on. What anyone else does is up to them and they are completely entitled.

About ten years ago, I got a glimpse into a seldom-opened storage room on the lot where I worked at the time. It was crammed full of green cutter Moviolas, must have been at least a couple dozen. Projectionists still use splice tape, so it should be feasible and maybe even inexpensive to tool up for film cutting again.

Machines like that are still used by bulk processors for QC checking.

It is widely believed that Betamax was technically superior to VHS.

It is/was NOT, but even when I used to prove it, people still didn't believe me.

Now of course, you can't get them anymore so that particular Urban Myth will remain forever cast in stone.

(Before you all get excited, Betamax is NOT Betacam!!)

Although the old Betacam (not SP) tapes used to work in the Betamax machines. I'm sure the broadcasters were happy that Betamax didn't take off or they'd have had a larger wastage rate.

 

I can't comment, since I never owned or used one, but I do know a Betamax owner who swore by his old machine.

Here they usually check release prints on high speed projectors. They're actually gentler on the film than a Moviola, and they have feed and takeup spindles. The cutter model of Moviola was hand fed into a bag. NLE's are certainly more convenient in that respect, but they lack the traditional chair cut function.... ;-)

Most bulk duplicators have a rudimentary "rear projection" setup that allows every print to be watched at high speed as it is drawn out of the drying booths and wound onto a spool. This allows operators to spot any gross deformities in the print.

 

Moviolas/Steenbecks etc are still used for real time checking for defects in duplicating negatives.

Originally Sony said that Betamax tapes could be used by Betacam recroders, but they soon found that the internal tape transport (in the cassette) was not really up to the task of running at nine times the intended speed (they also tended to be somewhat noisy).

 

Hence they brought out "Proper" Betacam tapes optimized for that speed, but the transport is too loose for most Betamax machines, and so you tend to get poor head to tape contact, resulting in dropouts.

 

I was given a whole carton of brand new oxide Betacam tapes, which I thought would be a lifetime suppy for my Toshiba Betamax machine, but they aren't all that successful. At first I thought the VCR was faulty, but I managed to get some proper Betamax cassettes and they were fine. Well anyway, I only use it for transferring people's old Betamax tapes onto DVD now, so it doesn't really matter.

Some people worship anything with "Sony" written on it. No amount of facts will deter them.

All I am saying is that a lot of so-called "hard disc faults" are simply software problems, often the result of people's ineptitude or possibly the case getting thumped at precisely the wrong moment.

 

i found that lacie had a bad bug in the FW800 controller for their raids that used four drives, nothing to do with OS, ineptitude, or thumped. junk firmware or really bad implementation of FW800 stack, USB chipset worked fine.

As you say, the transport issue could vary from machine to machine, the guy I mentioned used the Betacam tapes without any problems.

That can be arranged, Max :) .

 

Just 200km south of you is the shop of our long-time cine-tech guy who starts to retire now over the next decade (he's a slow retiree). While we had to pay for a Steenbeck and Stellavox rigs & racks some years ago, he has now started to hand out 6-platers for free (at least for 16mm - not sure about 35), and throws in Perfo 16 machines as well as Arri cutters. David Auner from here recently profited from such a deal after a good word or two.

 

If you have the studio space, a solid flooring (weight concern) and the will to maintain them over the next decades, the "getting" isn't a problem. We will have him around tomorrow in our Swiss premises, replacing one of the belts on a 5-plater. There is nothing as convenient as projecting a freshly shot test reel on a screen or quickly checking work prints on a plater of you shoot on cine-film.

 

Cheers,

 

-Michael

This is not my email address... your point?

Hi Jim,

 

This is the first post you made here!

I hope this camera is achievable... we are working overtime and throwing a lot of resources at the project. We have great intentions to deliver a camera that is measurably more capable than what is currently available or that we see on the horizon from other companies. We have added some great industry consultants as "adult supervision" to our other assets to do such a project. We currently have a great design team, optical and electronic engineers, 3D CAD modeling, liquid laser prototype equipment, electron beam gun vapor deposition machines. 5 axis mills, full testing capability, a titanium casting plant and a strong sense that we can make it to the end of the line. The foundation of our project is a very innovative sensor. Specs are incredible. We hope that we can help make 2006 a very interesting year.

Stephen... the date on that post was Dec. 2005, a day or two after the "decision" was made to do this project. At that time, there were two of us on the RED team, Ted and I. There were three emails addresses at that time... 4K@red.com was one of them and designated as the "general" company email address. Very early in 2006, that email address was assigned to Joanne. So anything coming after Feb 2006 would have been from her. We were pretty busy at that time designing, engineering and prototyping the camera... and getting ready for our 1st NAB... that there probably wasn't enough supervision of what responses were made from that address. No excuses, just the way it was. BTW, if there is a physical address listed for RED Digital somewhere, it is not my home address... and if you call the RED phone number, I am not the one designated to answer the call.

 

Your posts seem more and more pointed at finding some discrepancy in my presentation than actually contributing to useful info about RED. I don't quite get it. You are a smart guy with plenty to offer. We communicate behind the scenes. If you have questions or inferences like this one, they could easily be cleared up in a quick email rather than forcing me to post clarifications on this board. If I don't respond to your post, then I must be lying about 4K@red.com. Not sure why you feel it is necessary to do this.

Nice try, baiting me with ad-hominem attacks.

 

Ad-hominem? Latin for "to the man", that would imply that I actually said "Ruairi, you are blah blah" not "Ruairi, you said a lame remark on your blog." The ONLY thing I said that was Ad-hominem was that you are a RED fanboy. The other remarks were about what you did, not who you are.
