EPIC Recording Resolutions

[Bruce Allen]

Very interesting. So, if this is correct, then in order to achieve "True 4K" (20- to 30% downsampling), you might have to go with FF35 with larger-than-PL lenses?

I think that many of the comments about Red "not being 4K" were because of the amount of noise.

With Epic FF35 you'll have much better noise and DR characteristics so I think you'd get a much better image. You'll be able to sharpen the footage more. So it will perceptually look higher-res.

Be very interesting to see PL lenses on FF35 vs S35. S35 would have a slight pixel edge but I think the FF35 shots would look better and maybe even sharper. Human perception of sharpness is weird.

For your crazy no-compromises IMAX feature you could use Nikons, Canons or Red's upcoming FF electronic lenses. But not completely necessary by any means. Just go shoot it, man! Even if it's "just" on 4K bayer. It'll look awesome.

What would "greater than 28mm image circle" PL mount lenses get you in terms of resolution?

Quick (probably wrong) calculations:

Assuming your spherical lens can completely cover the S35 Epic sensor...
S35 Epic for 1.85 can do 27.75 x 15 (4995 x 2700 13.48mp) instead of 24.9x13.46 (4800 x 2596 12.46mp)
S35 Epic for 2.35 can do 30 x 12.76 (5120 x 2180 11.16mp) instead of 24.9 x 10.6 (4800x2048 9.8mp)
S35 Epic for 16:9: no change

With the FF35 sensor you could keep on going from 24.9 x 14 all the way up to 36x24. Doubt most PL mount lenses would go there though. But it's awesome to have the option.

Having a 15mm tall sensor allows greater options for anamorphic.

It's about the same height as Red One. And the sensor has, basically, a native 2:1 ratio area.
It doesn't seem suited for Anamorphic at all, Jim, especially when compared to the FF35.

It's great to hear 4.5 is coming to the Red One.
Hurry! Every widescreen feature could do with that 20% performance boost.

Height is improved 21% - from 12.4mm to 15mm height.
My scratchings in the sand say 1.9 ratio, not 2.
In terms of pixels, you go from 6.23 megapixels (Red One) to 8.56 megapixels (Epic S35).
Combine that with the lower noise, higher DR, lower compression and higher frame rates and it should be pretty significant...

I agree - monstro is much better suited to anamorphic, of course. But for the people making anamorphic work on a Red One already, this should be a definite improvement.

Well, even Graeme, Mullen, Haakon and others agree that Red One is only (roughly) a 3.2K camera in terms of real resolution, so Red One is not "True 4K," so to speak. You need at least a 5K sensor, and 6K would be even better, to achieve "True 4K." That's where FF35 comes in... :weight_lift:

Hehe, I changed the finishing resolution on "The Short Days" 1080p, so I could use my 350D stuff, the new 5Dm2 in low light, and shoot overcranked stuff on Red One, etc. I'll have to wait for a second project before I aim for "True 4K." :gun:
