Well- if Arri would have 4K camera than they would be saying totally different things :) It also does not change fact that Alexa is a great camera.
For cinema 4k makes perfect sense- even 8k makes sense, where for home use it may be questionable.

Haha it kills me to think that I can have a 4K set-up at home :)
Damn I was at RED tent at 2011 NAB and watching that Dragon clip off the RED RAY was enough for me.
I really want my 2.5K now so bad.
Im even saving up for Scarlet so hopefully those frames play nice with each other :)

Here is ARRI's white paper on the matter. Very educational read.

It's for those, who keep saying that there is no difference between 2K and 4K scans etc.

I'll have to bookmark that for my clients.

It's for those who don't care about 4K. Or just want a good 2K image for less than a million dollars.

Pity we have to wait so long! Haha.

I went to red.com's Scarlet-X section for 10 minutes before. $$$

Well, do we really need to see the lines on actress' faces in 8k resolution? Or crooked teeth? Saliva? Blemishes?

Movies are about people. Not resolution.

Movies are about people. Not resolution.

The two aren't mutually exclusive. And why not see lines on an actor's face? Or crooked teeth? Obviously not ideal for all circumstances, but it's much easier to reduce resolution than gain it.

Many actors complain about the sharpness of HD, and want things softened.

I'm inclined to agree with everything Deakins said. The Alexa is the first cam that really fooled me into thinking it was film (In Time and The Avengers). The Red, with more resolution, and less DR, has been disappointing. The extra resolution makes it look not like film oftentimes but rather computery and artificial.

If Deakins says Alexa blown up to Imax looks fine I'm going to take his word for it. I believe he's also said that the Alexa had more detail than 35mm scans.

Another thing to keep in mind is how much resolution is actually being resolved in these cameras. 1080p from an Alexa and 1080p from a 7D is drastically different. A lot of people with Canon DSLRs think they are getting 1080p worth of resolution when they're really getting less than 720p (http://www.youtube.com/watch?v=Ox_EzLXOSzU) worth of resolution. With true 1080p as offered on an Alexa, I can see how the resolution can be enough for most applications.

While it's true that actors don't like high resolution on their closeups, we can't forget that films also include wide landscapes and establishing shots that can use the extra resolution.
