3K...

But scaled won't get you higher frame rates than full sensor, et least that's how I understand it.

Well as I understand it, the sensor is able to "record" 60fps in 4.5K.
The compression is not, and possibly the write speed of your CF or Drive (which depends on how much it is compressed).
So you if you imagine that compressing a 2k scaled version of the 4k is faster than compressing the original 4k, you could think that you might record 60fps of 2k scaled on CF and drives.

Jim, there IS and advantage to scaled vs. cropped. Depth of field, field of view and image magnification. There is a big difference between a 25mm and a 50mm, even if you stop down the 50 so the depth is the same. There is an amazing optical quality in using a longer focal length to achieve the same angle of view.

I agree, scaled does make a lot of sense in order to maintain 35mm DOF while saving storage space at the same time - if you don't want to go down the full blown 4k post route.

Damien, scaled is full sensor, windowed is cropped from the center of the sensor.

Currently RED does not offer any full frame option aside from 4K.

So you if you imagine that compressing a 2k scaled version of the 4k is faster than compressing the original 4k, you could think that you might record 60fps of 2k scaled on CF and drives.

Apparently 2K scaled taxes the sensor alot more than 4K full frame does due to the need to down-convert in camera for 2K (I read this in a post by Jim, sorry if it is not correct). So I don't think that's true Antoine.

You aren't losing any DOF when shooting scaled, only FOV. (crop factor)

Hi Alex,

That is not correct. Shooting scaled preserves the FOV (and arguably retains more resolution) - that's precisely why it's a better option. Shooting windowed is where you lose FOV (and DOF, in order to get that FOV back). I realize that scaled recording is a harder request for RED than just ditching half of the sensor and taking windowed pictures, but it's superiority in these two areas is why it keeps coming up. If the processing power just isn't there in the RED to get overcranked full-sensor readout, then that's one thing... but that was supposed to be a reality with the RAW port all along (as well as onboard with the scaled modes before they were axed from the feature list). If it is within RED's capability at some point to offer the feature, however, I don't really get why Jim is so vehemently against it.

Häakon, did you get my PM, your, my favorite file .mov is not loading anymore?

[Michael Morlan]

In response to those calling for a KISS methodology; have you dipped into the arcane engineering menus of a Varicam or CineAlta necessary to color these cameras? The RED One is incredibly simple compared to these kludged ENG cameras. (I don't know enough about SI-2K, Viper, etc. to compare them.)

Jim and the RED team: 3K! Damn! Thank you. (Time to update the workflow diagram again.)

Haakon,
I totally agree
We all have been there torturing the subject of scaling against cropping.
I also don't understand Jim's position on this subject...
In my opinion the 3K is weird, I guess it is the best compromise that can be at the moment, and cheers to that, but it's still a compromise.
Hope there is still hope:bleh:

[Andrew M.]

What about something like this?

This frame that is highlighted (not darkened) contains less pixels than the full 3k frame.

Oh and green == 2:1 frame height. Yellow is the smaller 3k equivalent 4k frame height.

4K with 3:1 is the same amount of data as 3K with 16:9

I would love to have 4K 3:1 at 60fps

It is 4096X1365

[Antoine Fabi]

I'm trying to put back my jaw in place.

3K 60fps is WAY better than what i expected.
The croping factor is very usable for me.

...and REDCODE 36 is better than 28 ? really ?

...You're an incredible crazy team

Cheers!
