ARRI ALEXA VS. RED ONE MYSTERIUM-X VS. RED ONE

[ElsaCaetano83]

ARRI Alexa is using a flat image , different ISO and different scale/zoom.

Is like comparing a light shot with a night shot and try to convince someone.

Are you trying to promote RED?

[HornSpeakersRGarbage]

Fuking jackass - this is not a video. Post a web page, fool.

[sbusumacinta]

Thank you for the effort but this test is unfair for every camera. Go see the ZACUTO website and great camera shot out and you will see why!

[pH4nTomPL4n3T]

Reams of Bayor interpolation at work here. Digital snake oil for the 21st century. All fail.

[laluch15]

FAKEEEE! I saw a real comparison between the ALEXA and an ARRICAM Studio and there is no big diference. The ALEXA is the Film Camera of the year. RED sucks.........

[longboardjoe]

But yes still non of these compare to the resolution that is achievable with 35mm film. and especially not 65mm uuuuggghhh

[longboardjoe]

An interesting Test, Although some of the info isn't really real world applied I feel but the Log-C is amazing. We just got done using the Alexa on a Java soft shoot and its latitude in the Log-C was picture perfect. cant wait to see the Color Corrected version. But interesting Tests thank you!.

[TheDM75]

35MM wins.

[diginando]

I think overall this is a good test, but to most DPs should take a look for themselves and compare the footage on a proper monitor.

Also note that worflows for both systems can affect your post work.

[khenpokunga88]

what is price the red one and arri ?

[DraSifisGr]

Personally i see that the Red One MX is the dominant

[beatlemarmot]

This test is worthless.

You can't judge critical IQ when it's being compressed through YouTube.

[gundorfdunderklumpen]

@beatlemarmot

I agree. too many unknowns. What lenses are they using? what light? what math?

I dont get it. I wish people would film people, architecture and nature for tests. When do we ever put test charts in commercials?

[TemplarReturns]

@beatlemarmot Very true. I've seen comparison images between Red M-X vs Arri ALEXA and to me, the ALEXA wins by a mile.

[rainerfilm]

you obviously don't understand the right hand rule.

[ThisOnesForReal]

I would be happy with either of these thanks.

[MarkyMark662]

Great that you guys took the time to do this! it was interesting but as others have said here some of the tests do not show anything that would be applicable to the real world.

Comparing the Alexa in LOG Space showing Milky Blacks (blacks lifted), to the Red in lin Space with the blacks closer to 0 is not fare. You really should convert the Elexa Footage to lin space and then bring all blacks down to 0.

If you need help doing this let me know, I know how to deal with this footage.

Thanks!!

[trettea]

@MarkyMark662

you are absolutely right!

this test is not about what looks best, is about what is best.

everybody complains that red images look better, but every pro knows that log-c images have more informations that could lead to a better finalization.

to me, log-c has a clear advantage, and it's more important to see that all colors are there, before worrying for the milky blacks.

besides, red has a much much greater definition...

[trettea]

@trettea

and thank you for your comments!

[MarkyMark662]

@trettea I think the RED RAW files are in LOG space, but putting it through Redcine converts it to LIN. I hope they do another test! The difference will be much less if they compare them accurately, but buy the time the test is done the EPIC will be out and this will all be obsolete information.

[patternagainst]

@trettea You're right. This is the same principle often used in scanning film negatives-- obtaining a digital original that contains as much info as possible so you can play with the blacks in post.

[trettea]

unfortunately i don't have the raw files anymore to check the resolution with the "alexa up-rezzed."

alexa has improved a lot during these last few months.

on january 5 we have a new test session with alexas and reds. i'll do some testing on the topic by then and post it.

thank you

alessandro

[SeanOcomesForYou]

Should have done a test with everything on all cameras set to native settings. and for people that sat through and saw the resolution test just know that if you up-rezed the Arri from the "2k" to the same resolution as the reds "4k" It would look as sharp as the Reds "4k" image

[changkukay]

what kind of test is this? gimme a break

[changkukay]

which kind of test is this? gimme a break

[theSVARTfilm]

Why didnt you compare M-X at 800ASA instead of 320?

Also why you didnt put 3dlut on the LOG-C material?

Why didnt you use REDlog gamma for some comparison shots?

This test shows nothing...

[trettea]

@theSVARTfilm

for sure your objections are reasonable. there could be thousands more tests to do.

but there are several ways to ask and tell. some are just more polite than others.

so if you like us to perform a test following your suggestions, no problem.

if you're just telling us that you read the book and our test sucks, please be our guest and show us how you can do better.

[wynnep]

I guess in my experience I see a definite difference from different color spaces to the raw. If you record right up to the edge of the histogram without clipping you can find detail in the raw that you'd have to dig for in different spaces. It also varies from camera/post software build.

[trettea]

@wynnep

just curious.

i understand that you need to go through some kind of debayering to see the raw image in a rgb monitor. this implies the application of some sort of color and gamma space.

the only way to see the real camera raw, as far as i know, is in speedgrade, where with an option you can see the real green or red, or blue pixels.

how do you get to see the raw image with no debayering and color space applied? are you sure you're talking about the real raw?

[sonne5]

Do you actually own this camara? If so, congrats! If I had 40K, I'd probably buy one myself. I'm an indie producer trying to produce my first 2 scripts.

[trettea]

@sonne5

good luck for your scripts!

where are you based?

[sonne5]

@trettea I live in West Virginia. lol. I'm about as far from Hollywood as one can be. Oddly enough, they are shooting a major movie in my next town over (it's called Super 8; it's being filmed by JJ Abrams). I'm gonna be an extra in a week or two. Thanks for wishing me luck! I'll need it.:) I got almost a dozen scripts done and working on more. I was working on novels, but nowadays they're extremely tough to sell and don't pay as well as they used to. Besides, movies are funner than books, imo

[sonne5]

what's the difference between Red One and Red One Mysterium? Or are they the same?

[trettea]

@sonne5

it is in fact difficult to tell the difference, mostly due to the compression of the video in youtube.

mysterium x has a little edge in sensitivity and in highlights, and a lot less noise in low lights.

it is in fact really a beautiful camera.

i also would like to make a specific test as soon as i have time, but i'd say there are a lot less problems with the rolling shutter issue.

even in quick pans sideways, i can see no vertical lines bend in any way.

i love this camera!

[Videocashonly]

i can't understand this test

[richardpurves]

@Videocashonly Me neither. They're comparing a 4K Red image with a 2K Alexa image at different ISO settings. It's hardly comparative?

[trettea]

@richardpurves

2k vs 4k is just alexa vs red.

different ISO where set to show different sensitivity with same luminance of the same picture. it means that Alexa has a higher sensitivity.

[richardpurves]

@trettea True sensitivity comparison is best done through video scopes. See the Art Adams article on Pro Video Coalition website for details.

[trettea]

@richardpurves

true.

[trettea]

@richardpurves

true.

[trettea]

@richardpurves

true.

interesting article, BTW.

thanks.

[wynnep]

It's kind of hard to form an opinion about the dynamic range without knowing what Color Space/Gamma Space the Reds were set to.

[trettea]

@wynnep

good point!

color space in the test was set to REDColor

Gamma Space to REDGamma.

all opther parameters where set to default.

color temperature was 5600 Kelvin

[trettea]

@wynnep

you're right.

but in my experience, color space and gamma space doesn't affect much in the extreme highlights and low lights. so changing color space and gamma can change how colors are distributed along the curve, but it doesn't change how deep the cameras can read into highlights and lowlights.

color space in the test was set to REDColor, gamma to REDGamma. all other parameters were set to default values.

[pangrac1]

What?

"Misterium" at 0:25 :D

WTF! Try to use spell checking next time!

[pangrac1]

But otherwise definetely thanks for your effort and work with this test!!!

[tobyjt87]

You should also show RED as log (i.e. R3d to Log / Redlog) to make a fair comparison.

[bokassa7]

ma che test è? che senso ha paragonare il raw a 4k delle red con un output HD, benchè RGB 444, della Arri? vorrei vedere i risultati con l'arriraw a 3k, così 'sto test non serve a nulla.

[trettea]

@bokassa7

3k arriraw? it's more a chimera than something real. as far as i know, it's not working yet. not at 3k.

besides.

i love the alexa, indeed, but the policy for raw recording is really something i do not understand. you have to spend more for the storage than for the camera itself!!

recording arriraw with alexa is like going to buy a ferrari for 60k dollars and then having to spend another 50k for the special custom size tires...

really makes no sense to me.

[Odellhoward69]

jack white can rock ANY guitar.

the camera is a tool that will always be improved, storytelling takes practice.

[soufianDEMOS]

Alexa also outputs RAW, you should have mentioned it. On top of that, you dont talk about compression. Alexa uses NONE ! While Redone uses MotionJPEG2000. 

[trettea]

hi.

All you say it's true indeed.

but our test is not a side by side comparison between the three cameras, but only between 3 specific parameters: framing, sensitivity and resolution.

we didn't add any comment just because we believe that everyone should make his own opinion.

my opinion is: for dynamic range and sensitivity, arri wins hands down.

for resolution, the opposite is true.

MX for red is really a huge step forward, especially in low lights.

i hope this test helps.
