RED Mattebox...

[Jannard]

We have abandoned the RED Mattebox program.

Due to the increase of capable 3rd party solutions, we see no reason to continue development of this product category. With Arri's new lineup, at more reasonable pricing, the Petroff system, Red Rock Micro, Chrosziel, Vocas and others providing solutions from top to bottom at all price points, it makes more sense for us to concentrate on camera and lens development.

[Simon Valderrama]

ah!
you mean also the clip-on one is already in store?

[Brandon Fraley]

good call. Could u develop a badass, cheap tripod instead an deliver it with my camera this month? ;)

[Jarred Land]

good call. Could u develop a badass, cheap tripod instead

I think thats even a more saturated market with even more great options :)


ah!
you mean also the clip-on one is already in store?

we are removing it now :)

[Kevin Wild]

I think thats even a more saturated market :)

Yes, an overpriced, flooded market. :-)

I think Red Rock is happy today about this announcement.

[Jannard]

We want to encourage 3rd party development for RED cameras. We started down this path because we didn't see any/many good choices for our customers. Other companies have stepped up and we are happy about that.

Jim

[Joe Vinson]

You guys have enabled a slew of new filmmakers, which in turn has allowed the third-party accessory market to flourish. I'm a little sad we won't see a finished RED mattebox, but I'm glad you'll be able to focus your efforts on the stuff you do best.

[Radoslav Karapetkov]

:umm:

hi microMattebox...

[C.H.Haskell]

I am sad to see anything RED developed get canned but I too feel this is best choice for the time being, bring those camera home! Thanks for the update Jim.

#1781...paid up for today so this is good news.

best

[Sven Seynaeve]

Seems this is a wise decision, there are indeed some other nice options on this subject. Most important is that Red cares at where you're really capable of doing , what others just can't....

[Mike Prevette]

What a smart and humble choice.

[Brian Broz]

Hopefully someone will come out with a lower cost 15mm (studio) swing-away system soon....

[Shawn Nelson]

Interesting, especially how way back in the day it was said that Viewfactor's matte box that we were all waiting on was folded into the Red one that now wont exist. Oh well, now I am super glad I bought the RedRock Red matte box setup.

[Drew Mylrea]

sounds like a good call.

[Antoine Fabi]

This is very professional thinking IMHO.

RED needs to be surrounded by 3rd party collaborators and encourage them.


...and also, maybe concentrate on what you do best = image!!! :)

Good call.

Antoine

[Simon Valderrama]

we are removing it now :)

Ah! What about a RED Film Festival with the matteboxes prototypes as a prize?
Red memorabilia! :biggrin:

[CK Olsen]

Good way to play the game. Oh, and speaking of Vocas... that there's one Suh-weet matte box!

[Meryem Ersoz]

Ok, so what is the nearest analogue to the RED mattebox. I have the more fully-featured Redrock ordered for camera #1, but was hoping to use RED's mattebox for camera #2. Because of its apparent weight and size, it looked perfect for nature and outdoors, which would have been its primary application.

Any suggestions?

[Shawn Bannon]

can I buy the clip-on prototype then?

[16x9 Inc]

Hopefully someone will come out with a lower cost 15mm (studio) swing-away system soon....

Have you seen the new Chrosziel Swing-Away solution?

[Mike Prevette]

16x9 is that 15mm studio or lightweight?

Good Call

[16x9 Inc]

16x9 is that 15mm studio or lightweight?

The Pix shown is on 15mm Lightweight Support Rods. However, the swing-away mechanism can accept a 15mm to 15mm adapter for Studio.

[Jarred Land]

heh heh... 16x9 comes out of the woodwork :) Welcome.

congratulation - perfect decision. take all your power and ressources in Red One, Scarlet, Epic and Red Ray - these are the important things to do.
And a good chance for all other 3rd party manufacturers to make a good business.

[vincelucero]

So will VF Curt be offering the mattebox instead? Sweet design man. Guess the Micro will do for now.

[16x9 Inc]

heh heh... 16x9 comes out of the woodwork :) Welcome.

Thanks. Amazing forum. We'll be involved as much as possible.

[David Collard]

Nice call, Jim. Those other vendors have been working hard and are now providing reasonably priced options, thanks to you.

[Brook Willard]

I'll respect the decision if it's final... but I still want to urge you in the strongest possible terms to release your clip-on. That thing is hands-down awesome and wasn't more than about 5 little features from being ready to ship.

I'll buy a freaking prototype if it's on the table. That thing rocked. Losing the swing-away matte box is one thing, but your little 4x5 clip-on was a party in the shape of a matte box.

[Evin Grant]

Jim

Did I miss something? Where is this new Arri line up?

[David Mutchler]

So will VF Curt be offering the mattebox instead? Sweet design man. Guess the Micro will do for now.

I too would like to know the answer to this. Everyone is saying "good call" on abandoning the mattebox, but I don't think so. I was looking forward to it.

I have to agree I really wanted that clip-on mattebox. sure hold off on a studio mattebox, but i've looked and don't see a clip-on mattebox quite as cool as the REDs.

GREAT!!!!!!!!!!!!!!!!!!

Well said message to all today's and the future RED third parties.

[James Brundige]

The Red Rock Micro will be great for studio work, but I'd like a good clip on for remote and hand held. The Red looked cool for that.

Anybody found a good clip-on mattebox?

[Zakaree Sandberg]

my new mattebox- now for sale!

[Adrian T.]

Anybody found a good clip-on mattebox?

Arri LMB-5 or LMB-15.

[eyemark]

Vocas makes a very good clip on with one fixed and one rotating filterholder
(I do not work for them, I have been using their products for the last 5 years)

Do you know something we don't? :innocent:

I suppose Jim is meaning the MB-20 version 2.. with some different specs.

Hmm...

[Andreas Fernbrant]

Woh, that's a bummer.
I loved the prototype.

[PMascetta]

Now if I could just get that redrock tracking number...

[red i wanabe]

I guess I'll have to go back to makeing my special foam meat tray matteboxes. :)

I all seriousness there is a black foam meat tray on the front my camera right now.

Too bad that carbon fiber looked pretty sweet.
Give the designs for the clip on to another company, so they can make it.

[Tobias Straka]

Well that thing really looked sexy, but hey, I do think it's the right decision business-wise... We'd still buy the clip on though.

[david farland]

We have abandoned the RED Mattebox program.
Jim

total respect for you on this one Jim.......!!

I now hope we now hear an announcement from CVB on his matte box designs.

CVB........????

Cheers,

[Jeff Kilgroe]

I can understand not pursuing a swing-away design... But I have to agree with others on the clip-on. The prototype looked great, couldn't have been that far off of complete. I don't think the market for clip-on matteboxes is overcrowded either.

[C.H.Haskell]

Have you seen the new Chrosziel Swing-Away solution?

http://www.16x9inc.com/images/web/ac-450-dsw.jpg


Nice, this seems like a solid swing solution for Chrosziel owners, Anyone RED owners use the 450-01 on their 18-50 RED glass?

Welcome 16x9.

[Adam Jeal]

What about the Scarlet clip-on mattebox?

[Nicholas Shields]

Great move! Now don't come back out til' build 16 is done! :)

Nick.

[Michele Gavazzeni]

Great idea!

RED is right on, as most of the time:sarcasm:

Especially with the RR Micro MB, there is nothing to complain about, it is an incredible good solution, and more so at the price point, so Jim's statement make total sense here, why continue to tap in to something, of which there is no need to, as the third party options are great, from the Arri to the RR Micro MB's there is plenty to chose from, and at all price points.

To me it is way better that RED put their energy and time on to much needed Lenses and the new cameras, as I have no complains for the RED ONE, apart waiting anciously for the now soon to come Build 16.

Even if Most of RED's accessories are just great solution, I would much prefer third parties to come in strong, as several already are, such ET, and let RED make cameras and lenses, by the tens of thousands, which are far more needed.

ciao

[Ralph B.]

I tell you what you might want to look into.... an Underwater Housing! Strictly as a business venture. Gates is selling the DEEP RED $20k for the RED one. THAT's a lot a cash for not a lot of tech. I mean, I know there is engineering in there but nothing like a RED camera or Lens.

On second thought, stick to the lenses, cameras, and display products, don't waste energy. If you've got some extra accessory design man hours perhaps design one for the Scarlet. You guys will be in a great position to customize a housing for that camera. It would quickly be THE underwater capture device, for features or anyone that really enjoys scuba diving. And if you can pick up a few extra incremental $$$ while you are at it, why not?

[Andrew Hewlett]

Wow...I'm super stoked that I bought my Red Rock Mattebox without waiting for the Red swing away! I think the Red Rock Mattebox would be a hard competitor at the price point and since Red and Red Rock are looking to change the film industry, they might as well do it together without competing.

Good call Jim! Now, I would like to hear more about the Arri price change. I'm guessing it'll still be the same price as multiple Red Rock MBs.

[HDPioneers.com]

I, too, welcome more info on this "New Arri Lineup"

the MB-20 series isn't that new....or cheap.

[donatello b]

I'll buy a freaking prototype if it's on the table. That thing rocked. Losing the swing-away matte box is one thing, but your little 4x5 clip-on was a party in the shape of a matte box.

i'll pay $1 more then Brook !!!

[KETCH ROSSi]

Have you seen the new Chrosziel Swing-Away solution?




16x9, what is the price on this unit.

ciao

[Brigham Edgar]

Good call Jim.

Im sure you would have had a lot of customers for the mattebox but personally i would prefer to have all efforts, staff, budget and drive into developing the existing camera into something bullet proof and 'fixing' and developing your workflow for this technology. I'm sure you guys are, but heh, let's get the existing gear working properly to 'finish off' the doubters of RED and for current owners to breathe a little easier with this thing.

RED have to be acknowledged for some astounding breakthroughs on many fronts and your ambitions for even more groundbreaking technology is aspiring and to be admired. But i'm a thorough supporter of scaling back some of the more unimportant things like the mattebox (as there are ample 3rd parties) and maybe even some of the other accessories and putting all efforts into the workflow and making the camera 'solid'. Fix/develop what there is now and then full steam ahead so to speak.

Applause for your decision and i hope to hear more very similar announcements in the future!

Cheers!

[millrick]

Thanks. Amazing forum. We'll be involved as much as possible.

any plans for Scarlet accessories?

[Curran Giddens]

I think VFS will start working on their "Arca" mattebox as soon as they start shipping the Mirus in June or July. There is also a section for the mattebox on the VFS forum:

http://viewfactor.net/forum/index.php?board=8.0

This was posted by Curt a couple hours ago in response to a question about the VFS mattebox:


As soon as we deliver on our current products and make our current customers happy we are going to be tackling several new products that should really change things in the industry. We will let you guys know what the plan is in terms of other products in the near future right after we start shipping Inclino, Impero, Origo, and Mirus.

[Jay A. Kelley]

There is a new Arri mattebox out there.. I hear the proto-type is completed, and there's another one as well.

I'm not sure how much I am allowed to say...

But, they will not be out for a while (more than 2 months).

When they are, hopefully will be able to arrange something for RED users.
I've also got something working with the lighting division. But still not ready yet.

Jay

[Craig Bowman]

Yes, focus on lenses!!

So about the 50-150mm... What's happening there?? Redesign, new parts??

Jarred, you seem to be nicely on the inside. Any news is better than silence!

[Esteban Sosnitsky]

Although I think it is extremely good to focus on delivering cameras, I also think that certain accessories, as important as the matte box, (masked for red lenses),clip on, remote control, etc should be available from red. I trust and have seen the third party stuff, and I think that is really good, (probably I'll have to buy some of it too!!) but the commitment that you (RED) have shown developing everything you put out in the market is invaluable. In other words, I hope once you have the camera production up and running smoothly, we will see a series of accessories developed in a brand new way that only you have been able to do. Looking forward to whatever comes next.
Cheers.

[Mark K.]

A PL-mount lens is a PL-mount lens whichever way you slice it, and accessories standardized for PL-mount lenses should work just fine regardless of the manufacturer. RedrockMicro have some terrific accessories, and the ARRI prototypes I saw at NAB looked great too.

[Michael "Dorkman" Scott]

Woohoo! RedRock for the win!

[Alexander Mitchell]

Anyone have any photo's of the Arri mattebox prototypes?

Or any other info not already discussed in this thread?

Thanks.

[Brook Willard]

There was an Arri prototype matte box at NAB, but it was designed for prosumer cameras. Is that the one you're referring to, Jay?

Chrosziel 450-__ will not work with RED lenses as far as I know.
The Chrosziel is 110mm rear and the RED 18-50 and 50-150 are both 114mm (the 300mm is 117mm).

[Michael Stanmore]

Nice idea. Redrock's "red" setup is...pretty cool.

[Justin Kirchhoff]

I'm actually really happy with this announcement....Now I don't feel so guilty about purchasing the Red Rock mattebox. :)

[Mitch Gross]

Sorry to chime in late; just got back from traveling.

I think it's great that RED has decided to focus more on its core products. Spreading resources too thin can lead to delays and things falling through the cracks. The speed of development at RED is so fast that diluting the vision is not a good thing.

Arri has many current products (which Abel sells at special pricing to redusers) that work well with the RED. The MB20-II is a prime example, as is the LMB-15, which is a clip-on that is very much like the design of the prototype RED clip-on. There's also the big boy MB-14 for those really huge lenses.

Arri has a new prototype clip-on or rod-mount mattebox which was developed in consultation with Abel. It was designed specifically to work with the Sony PMW-EX1 but turned out so nice that it can be used for many other cameras. We showed it at our NAB booth and response has been very enthusiastic. Arri is doing some slight refinements to the initial prototype design and then we'll be rolling them out. When the refinements are complete we will see about compatibility with various lenses on the RED One. At this time I'm confident that it will work with most primes, but we don't want to make any promises before testing. Pricing has also not yet been determined, but it will be below even the cost of the LMB-15. When we know more you will know more.

[Alexander Mitchell]

Thanks for the info Eric & Mitch.

Mitch, any idea on price range of the new ARRI mattebox targeted toward the EX1 range of cameras?

[Rick Darge]

A million dollars...

[Shawn Nelson]

It boggles me that anyone is suggesting Arri would release a lineup of anything that's in line with Red pricing. I'd love to see it, but it would require them creating an entirely different pricing model.

[Mitch Gross]

As I said, there is no official pricing yet, but I think you'll be pleased. It will be significantly less than other matteboxes, even significantly less than the LMB-15, which is clip-on only.

[Mark Phelan]

Mitch,

Any indication on when ARRI will announce their new pricing?

[16x9 Inc]

Chrosziel 450-__ will not work with RED lenses as far as I know. The Chrosziel is 110mm rear and the RED 18-50 and 50-150 are both 114mm (the 300mm is 117mm).

You are correct. One solution is the Chrosziel 412-02F130 (Clamp-on). Has an opening of Ø130mm. Works with multiple lenses through the use of step-rings.

You can add the new Chrosziel DSW-400 for swing-away capabilities.

[Raphael Varandas]

Holly Mother... my chrosziel is getting happy...but I'm litle blue...
Any other matte advice fellas?
Thank You Jim...

[C.H.Haskell]

The Chrosziel is 110mm rear and the RED 18-50 and 50-150 are both 114mm (the 300mm is 117mm).

I understand this to be correct, but will it still vignette even if pushed up against the back of a 110mm rear of a Chrosziel 450-__? I notice the 18-50mm RED glass has such a large hood on it so I was hoping it might work.

I really am interested in the swing solution, I just dont want to have to invest in new rails for it....not sure if thats how it works, we shall see.

[Casey Green]

While I thought the Red Matte Box was an interesting idea, I think it is a wise decision for them to concentrate on the other products announced.

I have seen other companies take on too much or reinvent the wheel when they should stick to what they are good at or let other third party companies concentrate on their projects.

Good move, Jim.

[Teague Kennedy]

Just bought a RedRock. Solved that problem.

[Mark Pedersen]

Agree! The clip on looked GREAT. I have an Arri MB 20 II but that would be a nice clip on and was hoping to order.

Don't give it up!

[Iron Possum]

Hi Mitch,

do you know if Arri's new Mattebox will have a swingaway option and/or 138mm rear filter holder. I guess a tilt filter option would be out of the question for this price range too?

[Mitch Gross]

Based on the prototype, no on the swingaway and yes on the 138 filter holder as an option. The rear clamp ring is sized to accept the 138mm bellows back from the MB20. And yes, a tilt filter would be a bit much for this little mattebox.

I really don't know price and availability yet. The Arri engineer literally finished the final assembly of the prototypes in his hotel room before the show! Every day he swung by our booth to make sure the thing was holding together well and to gather comments we'd received for improvements in the design. It was very close to the finished piece but he came up with some unique little tweaks that he plans to incorporate. We can't wait to get them in.

So everyone knows, we very happily sell lots of Chrosziel matteboxes, as well as Vocas.

[Jason Ing]

What matte boxes will fit Red's upcoming 18-85? RedRock, Chrosziel, Petroff, Vocas, Arri? I'm primarily interested in the Petroff and Redrock. Does anyone know? Thanks.

[Cam Crowley]

What matte boxes will fit Red's upcoming 18-85? RedRock, Chrosziel, Petroff, Vocas, Arri? I'm primarily interested in the Petroff and Redrock. Does anyone know? Thanks.

I believe the RED18-85 is 139mm. Redrock will fit up to 144mm. Don't know about the Petroff. Somebody correct me if these figures are wrong.

Me thinks Redrock is going to do very well out of this :detective2:

[Mitch Gross]

For those who are curious, here's a photo of the Arri prototype mattebox, mounted here on the front of an EX1. Arri said today that delivery would be after June and price would be below $2000, perhaps dramatically below. It's a very different product for Arri, their first low-cost item for high volume shipping. And still with Arri quality of design and build. We'll let you know more when we know more.

Also the little single-sided follow focus is also new. Really sweet and adjustable. Not to be overlooked and it will be in the same price range as the mattebox.

[Mitch Gross]

The photo on the geared head was sort of a joke -- a pretty "inside baseball" one at that. This is a small, low-cost mattebox. It will not be swing-away. It will be for mounting to lightweight 15mm rods, although one can use standard adapters for mounting to either 15mm or 19mm sliding baseplate rods. I can't recall the part number, but we'll be getting in the first run sometime next month or shortly thereafter. If we have them in time for CineGear I'll try to bring them.

Don't forget about that followfocus. A fantastic low-cost alternative. The only one that's less expensive that I know that is still worth bothering is the new Zacuto unit. Vocas has a small followfocus as well which I think is in the same price range as the Arri (can't recall -- long week). And there's always the trusty FF4 and Chrosziel units. We sell them all.

And I wonder why there hasn't been huge interest in the LMB-5. That's essentially what the prototype RED clip-on mattebox was copying. I really like it's slightly bigger brother, the LMB-15. Very sexy beast, and affordable as well.

[KETCH ROSSi]

Yeah, I tough that it had ... to be an inside Joke.

BTW. I freaking LOVE the Arrihead II, After Cinegear I have to make a decision on the head, and that one is definitely on my list.

[Alexander Nikishin]

I've been using the Redrock mattebox for over a week now and it is top-grade especially considering the price.

Solid contstruction, unlimited rotateable-stages from 4x4 to 6x6. It's the all purpose studio-mattebox, all it's missing IMO is a clip-on feature.

[Barry Green]

Not truly 6x6 though. It's 5.65 x 6". But yes, it's a total no-brainer, nothing else compares at the price point.

[Mark Pedersen]

When I was at the Red booth at NAB, they said that you can fit an Arri MB20 II (138). It would be dumb of them to go 1 mm above the 138 standard.

http://www.reduser.net/forum/showthread.php?t=11852

It was discussed about a month ago. There was no definitive answer to the 139mm question from RED though, but it appears that this is the case. But as Jarred said, you'll be able to squeeze it into the Arri MB20.

[Jarred Land]

the outside diameter of the 18-85 is 142mm... the prototypes were a little smaller.

[Adrian T.]

the outside diameter of the 18-85 is 142mm... the prototypes were a little smaller.

Bummer! So this means it's not compatible to an MB20? :sad:

[Mitch Gross]

The Arri MB20 has a rear bellows assembly that can hold a 138mm filter. It therefore is physically larger than 138mm itself. I'll have to check the dimension of the opening, but 142mm is plausible. We'll have to see.

[Mitch Gross]

Arri just sent me dimensions on the rear rings of their matteboxes. They will work with the 18-85's 142mm diameter.

Rear ring diameters:

MB-18/19/20 - 143mm
MB-14 - 165mm

Yes Mitch.. I think i confirmed that earlier, thanks for going through the extra steps though.

But then we won't be able to use the bellows as a 138 mm pola filter holder.
Anyway, thanks for the clarification Mitch and Jarred.

You'll have to use 5.65 square filters for Polas on the MB-20. On the MB-14 you could use 5.5" round or 6x6 square. On either mattebox you can get square tray filter holders that house a large round filter with a little gear ring on the edge, so you turn the ring to rotate the filter instead of the tray itself.

I already tried begging for a 138mm retaining ring to be part of the front of the lens.

Hopefully someone will come out with a lower cost 15mm (studio) swing-away system soon....
Try Redrockmicro Matte Box. They have both 19mm & 15mm.
