Shooting 1.85 or 16:9 with EPIC

[Joe Taylor]

Hello All,

From reading the tech specs listed with the EPIC, it seems as of now that EPIC shoots natively in 2:1. Does anybody know if one will be able to shoot 1.85 or 16:9 footage right out of the camera without having to crop?

Well I guess you have to crop at some point. be it during recording - choosing a resolution, like you do with RED1. or in post.

Its native 2:1. so 16:9 is side cropped, if I am not mistaken.

I was just thinking the other day; the FULL AREA OF THE SENSOR of the S35 frame is 5556 mm X 2780 mm with 15.4 megapixels of coverage and with a 33.55mm image diagonal with look around within the FULL AREA OF THE SENSOR.

However the ACTIVE PIXEL ARRAY itself, what is recorded in the camera sensor is 5120 mm X 2700 mm with a 13.8 megapixels and a 31.26 Image Diagonal, with the strange Aspect Ratio of 1.896:1 that Steven Hilder gave the sensor the name of the X-35 Aspect Ratio as he calls it.

So let’s say that the ACTIVE PIXEL ARRAY of 31.26 is the maximum area that is required to cover the Lens Image Circle outline by Matthew in his Diameter Database. Of course never going over the 31.26 mm Diameter of the S35 or S35-X.

Now the 1.85:1 could be cut off from the top of the frame (just slightly) and take it to the edge of the 5120 mm frame area leaving just a bit more for the lenses to go wider on its coverage, the megapixels should be similar from leaving the 2700 mm of the top (possibly with a slight change, but not much).

Now for the smaller 2.40:1 or the 2:1 frame area it’s just a matter of cutting the top of the 2700 mm frame area, but keeping the width of 5120 mm area active. The 16.9:1 can be arranged accord ling to fit within the ACTIVE PIXEL ARRAY.

So it can actually work with existing High Quality Cine Lenses. All the Aspect Ratio fit well within the Red Pro Primes (25 mm at 34 mm of diagonal size and bigger) and the Arri/Zeiss Master Primes (16mm at 34 mm of diagonal size and bigger). It’s all about how far the Cine lenses can go out to cover the 5120 mm frame area, and that’s where Matthew Lens Image Diagonal Circle Chart of the Diagonal Database comes in.

The more I think about it, the more convincing this option it’s the better of two worlds. I was just thinking out loud. One more stop of ISO/ASA, a larger sensor still at 5.4 microns, and the new technology of modular assembly all wrap into one package. It’s like the Red One evolved into the S35 with all of its evolutionary advancements, but the lenses, tripods, lighting and all the other things remained the same, just pull the Red One out and put in the S35 or S35-X.

Of course as Jim likes to say; "Everything in life changes... including our camera specs and delivery dates..."

Thanks’ Matthew, your web page keeps on improving: http://web.me.com/ducloslenses/DataRef/ImgCir.html

Now that we had a peek at the new Red Epic X35/S35 your web page becomes more important, the actual real Image Circle needs to be covered without any real lens degrading. The database needs to show that a lens has at least the FULL ACTIVE PIXEL ARRAY of the X35/S35 frame of 31.26 Image Diameter. Eventually the Actual Camera will be on the market, now is the time to think about the glass.

We now know that the Image Circles in order to fit within the S35/X35 Image Circle has to be at least:

The FULL AREA OF THE SENSOR of the S35 frame is 5556 mm X 2780 mm with 15.4 megapixels of coverage and with a 33.55mm image including look around.
The FULL ACTIVE PIXEL ARRAY of the S35 Camera Sensor has a 31.26 mm Image Diameter with an Aspect Ratio of 1.896:1 and its 13.8 megapixels.

The 1.85:1 ASPECT RATIO is slightly less that the 1.896:1 Aspect Ratio, or if you want to go the other way it could also be 13.5 Megapixels, with a 30.67 Image Circle, and a 4996 mm X 2700 mm image.

The 2:1 IMAGE ARRAY has to be at least 30.91 mm covering the 5120 mm X 2560 mm with a 13.1 Megapixel area.

The 2.40:1 RECORDING AREA is 29.95 mm covering the 5120 mm X 2132 mm in a 10.9 Megapixels area.

Thanks’ Matthew, always looking forward to your new current updates! Thanks’ also to Steven Hilder for his chart.

Just a bit more of clarification, also copied form Matthew's Data Cirlce Data Base Page, fond in the Lens section of this Web page. All the best. To the Red Team your doing a GREAT job!
