I'll work on mirroring these as well @ www.red.ramjetfilms.com (http://www.red.ramjetfilms.com)

All of thes files will start with greenscreen_ and will be followed by the actual filename in order to distinguish them from the other red images on my mirror.

Thanks for the heads-up!

I still think Jarred's shot had more soul :laugh:

But of course. Either way, it looks like somebody needs to update their CamAlign chart...

I can't wait to get back from work and toss these into shake.

That is some clean beautiful blue/green ... wow.

Thanks link for the green screen series. It looks pretty good... but unless "one eyed jack" actually has a notch on the edge, it looks like a column of pixels is still missing, near the coordinate x=2937 in this image. Was this unrelated to the cable-runover issues that were fixed by a reboot?

We have said that "Frankie" is tempermental. Primarily due to the crude cabling issues. It is a miracle that she has held up as well as she has given that she was really designed for lab tests and not extended shooting. We have learned to give her a break and appreciate all she is giving us. Our 1st real cameras go together in December. All this goes away at that time. We would ask you not to pick at "Frankie" too much. She is pretty sensitive.

I think all of us appreciate the chance to "peek behind the curtains" at these early development tests, which no other camera manufacturer would share, and I hope my observations are not taken the wrong way! These images are fascinating to see and of course I'm looking forward to seeing what Red can do when it's finished, as well.

Insert obligatory keying test:

Obviously no integration or compositing work, just a key. And what a beautiful key it was. Two clicks. The matte did need .8px of gausian filtration because of some de-mosaic artifacts though.

Given time, you could extract a perfect key. Then again, this is just about the simplest green screen test one could conjur up. David Stump said you guys shotmotion and fine hair... will they be posting that on sunday?

Unreal. Absolutely unreal, and this isn't even the prototype finished camera or software!

very nice! it's fun to note also that one of the green Macbeth chart boxes keyed right along with the background.

I'm curious about something- right after David Stump visited Red and before any of the Red frames went up, someone (Jarred?) posted a very low-res photo of the greenscreen setup- for all I know taken by a cell phone- but the green background was very vivid. Now, looking at the green screen images from Stump's session, the background is very different. Did the lighting change that much? Look at the comparative values of blue, in particular on background:
R,G,B values Left: (Jarred?): (65, 237, 1) Right: (Stump): (7, 224, 161)

The colors on the charts look reasonably OK on the Red test, so it doesn't seem possible that the background should be so different, unless there was a tremendously different lighting setup- like about 5 stops more blue on the background- when the right hand photo was taken.

The "snap" is not color accurate (much too warm- look at the seeing eye) and has been saturated a ton. Stump's footage is out of our camera and displayed "flat". I would NOT make any opinions based on this.

I have heard about a "color matrix" in digital imaging systems, although I can't say I fully understand it. Is this something that happens in the Red camera somewhere between sensor-in and data-out? If so, does the color matrix have final parameters yet, or is it still in process?

Edit: To my surprise, I was actually able to manipulate the Red image at right to approximate the colors of the "snap", by using only Photoshop global curves & tweeks (not isolating any one color). So (in my limited understanding) it seems you could have this much difference just via a color matrix, and contrast curves. Interesting.

A sensor would ideally spit out a perfect D50 color balance. Since they don't ever hit it exactly, a color matrix is designed to "adjust" for the difference. Ours is a very mild correction.

Damn that's some clean keying!

Jim, after seeing images like this and those of the screening, I along with everyone else who receives a Red One owes you a fat box of cubans! :thumbup:

Jim,

I hope your ready for the OSCARs next year for Technical Achievement for RED 1.

Jason Ramsey

I now have most of the greenscreen shots up on my mirror. Please feel free to use it. I think I have 997 gig's of bandwidth left for this month, so I ain't hurtin too bad. :thumbsup:

The last couple should be up tonight as well.

Nah, they have to look down on him and the whole RED team for a decade or two before realizing it really was a good idea and then honoring him/them.

As cool as it is getting all these behind the scenes photos of RED testing from Jarred, I'm not sure that he should be left alone on set...

Blast! I was actually working in shake right now to make that same comp! :laugh:

Post it anyway. I wanna see the comparison. (Mine's just PS with Magic-Wand anyway)

Matthew Bennett, do you like Devon Aoki? I just spoke to her about an hour ago. Should I tell her you say hi next time I see her? Or just wait till Red is out and you can chroma yourself right next to her... It seens it just might be good enough for you to feel her touch you (now wether it is a kiss of a slap on the face that you feel, that is up to your "skills")

PS: Jarred finally lost it? Must be the wait for Red making him inpatient

I think RGB_4.tif isn't fully uploaded. Of course that is the one I pick to play with.

Brook Willard

11-16-2006, 07:26 PM

Unfortunately I tossed the script together, smiled to myself and quit without saving.

mikkowilson

11-16-2006, 07:27 PM

Yeah, I concure. Both RGB_4.tif and RGB_4half.tif are only 22MB. (not 74MB like the rest)

I'm getting an incomplete file error.

Then again if you look at the CML page you can see that a portion of the files & thumbnails are missing. I'm guessing the upload was interrupted.

Good. I was seeing the same thing with the 22 meg files. Some of the x'd out pics were still downloadable though. Others were not. I am just finishing getting the last two on the mirror right now

I just got back from the San Francisco Autodesk Systems Demonstration. They were projecting/keying/masking/color grading/editing a great deal of 35mm origin 2k DPX files... and you know what? I just sat there the whole time thinking to myself: "That would be infinitely easier to key if you had shot that on RED." "Wow... that's really soft." "What's with the lack of resolution?" "So much grain screwing up that key."

Another thing I noticed: they were trying to clean up an actress' face in an example, and I was thinking to myself "Most of that is just grain."

I think actresses may be the newest proponent of the silky smooth RED. Personally I think the grain free look is much more flattering and doesn't accent every pore. Which I guess is opposite of the commonly held view on HD.
