World's first side-by-side ARRI ALEXA and RED MysteriumX camera test
For our current film, Roland Emmerich's "Anonymous", a drama about Shakespeare (yes, you read this right. No destruction. No end of the world.), we just finished up three days of camera testing.
Not just any camera test, but the world's first side-by-side test of the new RED MysteriumX (which is the REDONE camera, with a brand new chip and a new software codec to go with it) and the ARRI ALEXA (which is a brand new camera, very different and way more compact than the current ARRI D-21). We were privileged to be provided by ARRI with a prototype of the camera, and by RED with one of the first delivery models of the Mysterium X.
Before I dive into the specifics, ladies and gentlemen, let me announce right here, on this blog, that
2010 IS THE YEAR THAT CELLULOID DIED.
Yes, all you physical-analog-film-lovers, I said it. Touch the smooth plasticky emulsion one last time and relish the memory. Both these two digital cameras simply blow film out of the water. Period.

Now, to be honest, I wish the names of these two would be more celebratory for such an event (my guess is the "mysteriumX" was named by the creators of "Godzilla vs Mothra", and the "ALEXA" for somebody's girlfriend?). But that's beside the point.
The point is, both these cameras can do what you could not accomplish with any film stock, not in your wildest dreams. Here's how they work:
The RED and the ALEXA, while accomplishing approximately the same amazing feat of creating clean, VERY low noise, pictures in candlelight conditions, work in slightly different ways.
The RED still has a chip that's basically rated at 320 ASA (or more like 200 ASA practically, as many DPs told me), but you can underexpose it in extreme ways with only very little addition of noise.
For instance, we shot two stops under (equivalent of 800ASA) without any significant addition of noise.
3 stops under (1600 ASA!) is still absolutely feasible, with more noticeable noise, of course. Even 4-5 stops under (3200/6400 ASA) is not out of the question, if you use a good noise removal tool (we tested with ARRI's Relativity software and The Foundry's Furnace for Nuke) and are OK with loss of detail ion the blacks. But it's possible.
The ALEXA has a chip rated at 800ASA. But even with that starting point, it's possible to underexpose significantly with only little loss. We actually went so far to test 4 stops under, the equivalent of 12,800 ASA! And, while of course extreme, I would not be beyond saying it's usable for a certain type of shots (documentary style). Basically, I was absolutely blown away that we even saw ANYTHING on the footage.
We recorded the RED footage on CF cards, at a data rate of 42MB/sec (the highest data rate RED offers). The ARRI footage was recorded on CODEX portable machines. The CODEX records on little removable harddisc RAIDs with a capacity of up to 5 hours each. The RED records to their own RED RAW format, at 4480x1920 resolution, which is currently only supported via the redcineX (in beta) software, but is already also being implemented by other software packages, such as Digital Fusion and Baselight.While ARRI would not say what on-board recording solution they will show at NAB, in our test the ARRI output a 4:4:4 dual-HD-SDI stream at 1920x1080 resolution, which can be recorded by any HD recorder. The CODEX that we used, creates internally their own implementation of a JPG2000 file. During output via Ethernet or other means, it creates 10bit DPX files from the JPG2000s. In terms of file size, the Redraw 42 and JPG2000 are fairly similar. JPG2000 is a 1:4 compression, so about 2MB/frame. The Redraw comes to about 1.75MB/frame (at 24fps).
The DP for "Anonymous" is Anna Foerster. Anna started with Roland as DP for the miniature shoot of "Independence Day", and advanced to second unit director on many of his films, and is now also a director (she directed episodes of "Criminal Minds"). She prepared several lighting setups, one being a Vermeer-painting-like interior scene (pictured) and the other a greenscreen test setup, obviously of great importance to us. (attached are before-and-after pics of the greenscreen test).
At this point in time, I don't want to publish exact comparison details, because the ARRI ALEXA is a prototype camera. It will be shown at NAB and delivered in June this year. So not all the specs are finished yet. But I have to say, no matter what the final details will be - this is a damn fine camera, and the range of the chip is simply incredible. The RED Mysterium X is already shipping, and all I can say is - go out and test it for yourself, you'll be amazed.
So, it turns out that both cameras, in terms of performance of the chip, are very similar. And I'm not saying this for some bullshit political correctness reason, but because it's the truth. Since the ARRI is a prototype, and the RED software is still in beta, I don't want to go into the finer details that we found, because they can change at any point in time.
I've attached some pictures from the test shoot, a daylight/candlelight scene and a greenscreen shot (the raw, uncorrected footage and the keyed result). Do to the limitations of this blog format, these are just downrez'd JPGs, but even here you can see what I'm talking about. I will prepare links to high-rez files soon. The greenscreen footage of both cameras was very clean and - especially for 800 ASA, had very low grain/noise. While you still need post noise reduction to get a perfect key in hair details or the semi-transparent collar of the lady in the picture, we only had to apply very little NR, and it didn't create any visible softness in the picture.
"Tracking Marc" will return next week: Shooting HDRIs for CG lighting and textures.
























I believe the 800 base asa comes from RED themselves, I believe that is what they have rated it at in the new manual.
Hi Jamie,
I actually agree with some of your points.
I agree that I would not RECOMMEND to shoot above 2000 ASA with the RED and I'm actually not saying I recommend it. I'm saying in the blog that more than 1600 ASA is "not out of the question". And that's true.
I was told we were recording Redcode 42 for 4.5K. I will double-check that fact.
But I'm wondering how you arrived at the conclusion that the sensor is 800ASA?
Now, regarding my statement that film is dead. I have been waiting for someone to comment on that (even though I didn't expect it from a DIT), and absolutely have to disagree with you.
First, it's my opinion (an that's all this is in a blog - an opinion), but it's far from "quite utter hype".
You're saying RED can't compare 100% to film yet. True. But have you tested the ARRI? The ARRI actually has greater dynamic range and better color "stability" (for lack of a better word) than the RED (and its color space).
But more importantly why does it NEED to compare 100% to film? Fact is that these are two different formats, so while film might still have one point it does better (than the RED), digital has dozens of other points that film can't even compare with. For instance, a stable picture, longer "recording" times, better on-set picture quality (important for visual effects line-ups) and an extremely fast and way cheaper digital post workflow (both extremely important points for visual effects). And I would prefer the picture of a highspeed PHANTOM digital camera anytime over a Photosonics 35mm.
Then there's always a big question about PRACTICALITY. I've heard thousands of discussions about highlight details. But the point is that a CINEMA RELEASE PRINT, done in a highspeed copy process, loses any of these minute dynamic range advantages you may have during shooting BY FAR. All these beautiful highlights will be blown out and GONE. Same goes for a DCP. And especially a Bluray.
And if a DP exposes so badly that you NEED to bring these minute highlight details so far back down to make the difference to film visible and the final print, than he probably shouldn't be a DP in the first place, since you can see on your on-set monitor (and waveform) what your'e exposing.
As a visual effects supervisor, I have to look out for quality and workflow issues. As a producer, I have to look at costs. In BOTH cases, digital wins over film. That's why I wrote this.
Cheers, Marc
Marc,
With all due respect I have to point out some of the technical specs you mentioned regarding the Red Mysterium X sensor are incorrect.
First the mysterium X sensor is not baselined at ISO 320 as was with the original Mysterium sensor .
The Mysterium X can be baselined at ISO 800 in daylight.
In my detailed shooting experience with multiple Mysterium X sensors I discovered ISO 3200 and ISO 6400 are not recommended due to the amount of noise in the shadows for high quality imagery. One of the leading post production facilities in Los Angeles who has perhaps the most experience with Red post production is recommending to not go above ISO 2000-2500.
In addition the new Redcode 42 codec does not allowing for recording the full 4K 16x9 resolution and additionally cannot record above 25FPS for the other 4K resolution modes. This is currently due to the media recording devices (CF, Red Raid and Red Ram) not be capable of supporting higher frame rates with Redcode 42 codec.
Your comment regarding "film is dead" is to say the least quite utter hype and severely overstated. It seems every five to ten years somebody has to make this bold statement just to shake up the production community.
Motion picture film as of today still offers higher dynamic range (especially in the highlights), better color space, and increased high speed frame rate options (no codec restriction here).
I just completed several weeks of extensive shooting with multiple Mysterium X cameras and the sensor still lacks the dynamic range (especially in the highlights) which 35mm motion picture is capable of capturing.
Secondly the new redcolor (color space) is still lacking compared to other digital cinema cameras such as Sony F35 which offers S Gamut.
Now that all said the next generation of Red camera's "Epic" is going to be quite interesting to work with especially given the retail price point.
