  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

NAB13- RED MOTION MOUNT

Mark Pugh said:
What are the exposed surfaces of the mount made of? Glass, or polymer like the Tessive filter?

Funny how people keep thinking that.. its not the polymer Tessive. Its made out of optical glass, our same glass as we use in our OLPF. Thats how we were able to slip in a layer of IR cut on the front glass and a AR filter on the back to eliminate stray reflections from multiple layers.

Phew. Sounds good. Thanks, Jarred.

It is polarized.. but since it is linear you can still use Circular polarizer and get the normal effect that the circular polarizer gives you on a standard camera. If you want for some reason to completely remove the polarization , you can add a quarter wave plate in front.

I did not know that...

This is a very good news making the Motion Mount EVER more interesting, some people just simply fail to understand how important is and how much more "BETTER" makes an image, in Depth, contrast and color rendition amongst another benefits, which can not be done in post in equal ways, as Polarization is simply one of those MUST have ON capture filters, and it is also fantastic that you can still a Circular Polarizer, even so now will be only but of use in particular situation, allowing for the camera set up to be even lighter smaller for most of the times, as the MB will no longer need to not only not have Filter Stages for the ND's unless one needs to use GND's, but also now the need for a Circular Polarizer Rotating 138mm filter can be also removed entirely in most situations, in turn allowing for a smaller lighter more portable MB.


GREAT JOB RED!!

Now I really Cant wait to get the Motion Mount in action on M8... ;)


Now al we can hope is that it goes on the store within the next few days so to be able to do some filming with during my Summer vacations in the Italian Beaches before I get back to LA... ;)

Jarred,

The Motion Mount acts like a linear polariser? Not sure I understand your statement. Does the linear polarization of the Motion Mount not give you the expected cut in reflected light and darkened skys? You hint that to get this optical effect you would use a circular polarizer? Can you actually add a quater wave plate on the front of a lens and be effective? I am a little confused is a clarification possible?

Although a polariser is a truly handy filter it is often not the ideal filter for faces as the removal of reflected light from a face can result in pasty or undesirable skin rendition.
 
Tom, a Linear polarizer differs form a Circular Polarizer as the Circular has a Quarter Wave Plate in the back, but as Jarred said you can add it if needed while using the Motion Mount.

Just remember that Linear Polarization filter in the Motion Mount, blocks light reflections and acts in a different way then the "Rotating" Linear or Circular Polarizer, and for this in some occasions a "Rotating" Polarizer will be needed.

Because many times it serves you best to be able to actually hunt down such unwanted reflections in reference to were they are and the needed framing and eliminate them as needed, vs. a Polarizer that it is not rotating which will allow for cutting reflection only in that direction in which it stands with your framing and it remains directly linked to it and not free of rotation to allow the relier said.

For me, actually been able to have an all time Polarizer in camera is viewed as a really great thing, as I see far more benefits then none, only negative been the loss of light, but easily overcomes with such an incredible sensitivity that the Red Epic sports even more so now with Dragon!


To add, the more I understand the Motion Mount the more I see what piece of wonder RED just created!!
 
Ketch,

I have rarely used linear polarisers but from first principles they should both act upon the image in the same way? I understood circular polarisers have only become popular because they do not affect SLR AF and exposure systems. I do love polarisers but they have a definite and particular effect on the look of an image. While this affect is mostly positive its not something I want all the time for every shoot. Still unsure what this polarisation effect if any means for the Magic Mount? Could somebody from Red chip in?
 
Jarred, is it already for sale ? Cant find inside the store tho

Not up in the store yet, but it would appear that it's going to be available dangerously soon.


Just to give a thumbs up to Red here too. At NAB 2013 the Canon EF Motion Mount was said to be in the works, but it was going to take longer to get to market compared to the PL version. It would appear at first glance it might be sooner than we all previously thought.
 
Edit - Nevermind. Was just saying I'd like to see this technology incorporated into the camera body at some point in the future, instead of it being tied in with the lens mounts.

I was just thinking about the possibilities. Those things came in mind:
1.) with meta-data about ND-filtration in every frame we could change it during shots and compensate/"normalize" in RCX
2.) automatic compensation via ND for ramps
3.) this could even allow a complete automatic ND mode (nice for long shots, time-lapse etc.)
...

The name "Motion Mount" is a understatement, it should be called "Magic Mount" or something like that, because it magically turns your camera into a new one (again). ;)

Absolutely. You give us cash, we will trade you for a mount :)

Directing a feature on my Scarlet starting October 5th. Would pigs fly before our production could pay for one of these beauties to test in the field on a 6 week shoot?
 
It is unlike any other company; RED has given back so much through trade ins or upgrades. I cannot believe how many people think EVERYTHING should be a "Trade In"...I don't see that with ANY other company...It is a double edged sword; you give more they ask for more.

Soft Shutter: opens and closes in a Sine Wave
Square Shutter: Opens and closes on/off

I'm picturing the Soft Shutter to approximate a spinning mirror as light "fades" in and out of exposure. There's def way more technical dudes here than I am So I will not even try to explain certain things as I come across them but describe them as I understand them.

Hi Jason - If you have the chance to test out the Motion Mount while using strobes, I would love to hear any results you can offer an opinion on.

Tom,

first of all, in case my prior post was not clear, what I meant by reminding you that Jarred said you can add a Quarter Wave plate to the Motion Mount, that is to make understood that if need or like to eliminate the Polarization, you can do that on the Motion Mount, of course as Jarred said, this is to be placed in the front, while in the Circular polarizer the Quarter Wave plate is placed in the back as a second layer or element of the Filter itself.

And that if you desire for the Circular Polarizer you can just use it as you would normally do and will have no different effect then if you had no polarization at all in the motion mount itself, as the Back Quarter Wave plate incorporated in the Circular Polarizer itself will cancel out the Motion Mount Linear Polarizer, at list it should work this way, unless there is something more to the Motion Mount I am not aware of, like an additional cover plate filter in front of the filter it self, by I do not think this is the case.

As for any difference in Image quality and or look form a "Linear" to a "Circular" Polarizer, there is absolutely NONE, as they are one and the same, just that as I said above the Circular has the "Wave Plate" incorporated as to allow AF cameras to have no undesirable effect during the AF action.

So with the RED Epic, been a Cinema Camera, you would ideally be more then okay with the Linear, unless the AF on the Canon mount using Canon Electronic lenses in AF mode, is to be effected in the same as in a DSLR, in that case you would need a Circular Polarizer.

I am generally not too great at explaining Technical stuff, Language barriers mostly, but also because my ways of explaining some stuff get a bit twisted...

I am better served shooting then explaining stuff... But I hope I made sense and answered your question... ;)
