No you haven't missed a thing... The format page has been updated. No 1080p/720p HD RGB modes listed anymore.

It looks to be RAW PORT only, most likely the largest cropped image that can overcrank to 120.
Interesting to note that there is no way to overcrank now and use the whole 35mm sensor unless you go RAW PORT...according to the list...am I correct?
Maybe the list now only contains implemented features, in preparation for the first 50.

I imagine that 2k scaled RAW is likely to be still in development going by the chart. ;)
And BTW I don't believe that 2760×1270 pixels is 16:9
16:9 is a ratio of 1.778 (3dp)
This is 2.173 (3dp)...which is more 19(ish):9

I'm going to go typo because 4520/2 is 2260. (IBloom stops realizes his forum habit is getting out of control... switchs momentarily to Dashboard to double check his math... then presses submit)

I'm assumming this tech spec is for the initial release feature set and the 1080p/720p will be enabled in the near future!
Bit of a bummer not having preview at 1270p, again hoping this will be "future feature enabled"
the use of our red will be 50% broadcast (documentarty and 50% feature theatre release). I guess 2k windowed and downconvert to 1080p/720p?? for all broadcast.

Interesting... good find! Hope this doesn't get the whole cine / efp / eng debate all overheated again. Hopefully a fantastic solution will be found for all in the end and that this will be part of it. I think I'm going to duck out of the forums for a while though ;) You guys who are buying the camera can debate the relative merits of all of this..

Bruce, I hope that is not true.:angry03: :innocent:
You have been a great contributor on many levels, you have incredible post/graphics skills that I hope to employ on a freelance basis AND if you will remember I made you a great offer in a pm and I still stand behind it for the right project. I spent 3 1/2 years flat on my back not able to do anything -- Do not doubt my very strong desire to do great work with great people like yourself and others here... I have been fortunate as of late, my resources are growing and I want to spread the good karma.
Cheers -- Andrew
ps- your RED # should not be "I wish"... Put mine in there, there will be many opportunities that I am working now and I am not a graphics god -- we can work it out.

Shouldn't 2K's frame rate be max 60? Because it says 120fps max, and then goes on to say that you can do max 60 in recode, and can't use RAW... So how could you go up to 120fps in that mode?
Bruce Allen

Thanks Andrew. I think a lot of Reduser folks will be working together. There's a lot of talent here. I can't wait until 6 months' time, when we're chatting about all of the cool work everyone's making. That'll really be the time to be thankful. Good night and cheers!

Looks like there was a "Pull!".
The more we look at ExpressCard's performance and standalone format (not SATA), along with it's pricing... the less we like it. It is on the chopping block waiting for me to say "Pull!".

Yeah… I just found that out myself, any Red People could comment on this slight anomaly?:detective2:

Good catch. 1270p is 2260 x 1270 pixels, progressive scan.
2K RAW can be pulled from the S16mm central area of the sensor at up to 120fps, but 2K REDCODE RAW operates up to 60fps.
With S16mm optics, the RAW PORT works at 2K+, rather than 2K, you would create previews from your DDR. Of course you still have EVF/LCD output.
Usual disclaimer, specifications subject to change... etc

Is the 2k raw scaled feature in the making or has it been dropped?

Hi Stuart
When will the Scaled 2k by available so we can shoot 2k with 35mm glass?

I'm confused. Why would you have to use S16mm lenses? Why wouldn't it work with larger lenses?
And correct me if I'm wrong, but I thought the max for redcode would be 100fps, not 60fps. Wasn't that going to be part of a dual boot option?

Stuart, does this mean that overcranking from the full sensor area (35mm) is possible without having to use the RAW PORT? From looking at the chart, that doesn't seem to be the case...
Stuart English

It would, but on a 35mm lens you would be using the central portion of that lens, which is equivalent to S16mm optical coverage of the sensor.

Thanks Stuart. That's what I thought. So 2k+ Raw would work with 35mm optics as well (granted with the characteristics of cropped 35mm), right?
And, according to the new format specs, the highest possible frame rate of any Redcode format would be 60fps (2k)?

The max frame rate recording 4K RAW is 60fps and 4K REDCODE RAW is 30fps.
Using the central area (Super 16mm optical coverage) of the sensor we can record significantly faster frame rates using 2K REDCODE RAW.
The specs at red.com currently say 2K REDCODE RAW is up to 60fps, but that will be updated in the next 24 hours.

Ah ha! Just like what phantom cameras are doing?
Then, would it be possible to do something like 1000fps and over
if we do in something like 720? I wouldn't really mind shooting
in Low-res and blow it up for ultra high speed stuff.
Since you guys are doing two bootable firmware type of thingy,
maybe we could do a third one, with super high frame rates with
less resolutions?
Just thinking.

So that means no 60 fps in 2K scaled mode when using 35mm glass ?
I am sad.

Just to bring in a note of reality, the highest speed Red has ever mentioned was 120 fps.
Note that there are many links in the imaging chain (image sensor, analog amp, ADC, FPGA, data link, storage device) and each one has its own maximum speed. Using a cropped view reduces total bits per frame but that only helps the digital parts of the chain. There are probably still minimum shutter time and frame time limits on the sensor, analog section and ADC.

Um,
Just out of curiosity Stuart from my understanding of bayer pattern sampling there shouldn't be any concept of "scaled" IE wouldn't that screw up your Matrix?

Not if you scale by skipping every other group of photosites. Theoretically, it should be possible.

Just when I started to get my head around the shooting formats change (as we were told they might) I think I wait for Gregor Hagey to conduct his test. I'll probably visit just so I can figure this all out again.
I hope more features are coming. I hope 720p or 1080p 120fps or even 100fps will be possible.
