"I shot a lot of tests; we compared the Epic, the Alexa, the Canon 5D & 7D, and Kodak 5219 and 5213. I was really happy with the Epic. There's a lot to say about Epic vs. the Alexa. I feel that there is more detail with the Epic, sometimes too much, and the bokeh's are much rounder. Also the Epic is very light and compact. I didn't want to shoot handheld with the weight and bulk of an Alexa and a Codex recorder. In addition, the Epic gave us the ability to quickly go from 24fps to 300fps with the same camera body; that was a big advantage."
"We captured in 5K, cropping a 2:40:1 window out of the 1:90:1 frame. We tested different compressions at 5K, and my eye wasn't able to see the difference between 3:1 and 5:1, but we started to see a bit of difference at 6:1. So we shot 5K with 5:1 compression except for the 300-fps shots, which are 2K with 6:1 compression. They have an interesting texture "
QUESTION: There are many moments with reduced depth of field, like the shots of Stephanie in her hospital bed.
"That's a choice of mise-en-scene that was reinforced by the Epic 5K mode. In that mode, the sensor is much larger than S35mm. A 40mm lens with the Epic is [in 5K mode] is about the same as a 35mm lens in Super 35 "
I guess we can add him as an 800 member in the 320 vs 800 debate. Love how he barely checks his waveform! I have to assume he's checking the traffic lights though..."I set it at ISO 800 and worked with my light meter as I would with film. That way, I could shoot very quickly. When you're working on a stage and you have time, you can consult the waveform monitor and have a video village of calibrated monitors, but when you are on a set with a handheld camera and shooting with our a rehearsal, which often happens with Jacques (his director), you take a quick reading and you go!"
"We used the Red Gamma 2 display LUT for the monitor image. It has reinforced blacks, but it's still low contrast"
"I have shot commercials with the Alexa in ProRes. You turn on the monitor, and everyone's happy. You feel like you're watching TV. There's a kind of ease to it; there is already a result that is satisfactory. That worries me. I think the Epic is a camera that's more orientated toward postproduction. Of course, each film is a different case. You can also shoot Alexa in ArriRaw with a digital imaging technician."
QUESTION: You finished the film at 4K resolution. Why did you project 2K at Cannes?
"The 4K image was too defined, too digital, too hard; there were too many things in it. The 2K seemed true."
Nice thread Nick, thanks for taking the time!
Ah... I really hate the "because it is "better" arguments.
These, I can all see, follow, understand and agree with.
Arri and RED made different choices in their designs.
Thus the cameras are different.
There are even a few more differences, but it is good to see someone being able to articulate which differences counted for which production...
I also think the "screen in 2k" argument has some merit.
As we don't mostly shoot charts, there are more qualities to an end-image than details.
Of course, I know RED does not necessarily agree with this...
Even when it comes from someone using RED...
But it is a nice reflection, as compared to the 48 fps debate going on here.
Hahaha
In addition to mechanics, the issue with shooting on stills lenses is consistency. How consistent is the quality of the various lenses from the given manufacturer, and more important, how well do they match from lens model to lens model? It is not an issue in the stills world, but in the cine world we shoot with a given set of lenses on a project because they are designed to match well to one another. Color, contrast, focus falloff, chromatic aberration, geometry, flaring, veiling, center to edge brightness, etc. There are many aspects to a lens beyond resolving power and mechanical construction. Cooke lenses are all designed with similar looks so that they can be intercut within a scene well. Same with Zeiss, RPP and others. This is often not true of stills lenses.

This may be true, but the highest end pro stills lines...especially Leica, Contax, Hasselblad, etc....were well known for maintaining consistent looks. As long as you purchase lenses from a matching "era", the differences are usually negligible. Especially when shooting in RAW when you can grade the small inconsistencies out. Hey, you yourself used to own and rent a Contax set for use on Aaton mount...you should know!
That being said, you are of course MORE LIKELY to get even closer matching looks from a Cine set of lenses, where all the lenses were usually made at the exact same time, have very similar serial numbers, and were designed to resolve on film in a twinning way.
But a matching set of pro stills lenses can get you far enough...especially in a RAW world.
I was wondering, do the Leica still lenses have the same "look" as their cinema lens? Or what Leica still lenses have a similar look to Leica cinema lenses?
Agreed, I thought his 2K screening POV was pretty interesting too. And I also liked how specific he was for choosing Epic. Didn't seem shrouded in the usual demagoguery.
I have actually never had the chance to see anything screened in 4k but I imagine if you don't want the super sharp look then adding softness or grain etc in post and still screening in 4k would be a better approach then screening in 2k because 2k is digitally softer and softened 4k would be more organicallyish.
I does seem like we have reached a point where higher resolution and sharper images is not necessarily better or needed and at this point it's just a matter of purpose and preference.
On the Format and Compression He Used (5K @ 5:1):
So his 5:1 analysis and decision matches Ridley's on Prometheus (though they at times used 3:1 on very busy shots, with heavy water or vegetation).
General Shooting Advice
With 4K or theatrical delivery in mind, it's common for most productions to shoot with a REDCODE compression ratio between 5:1 and 8:1 when shooting at 5K or 4K resolutions. Lower compression ratios like 3:1 work well for scenes with high frequency detail or if your intention is to pull stills from your material.
When shooting at formats below 4K resolution (such at 3K, 2K, or 1K) it's advised to shoot at the highest possible REDCODE compression ratio available for your frame rate and resolution choices to yield the highest quality image for up-scaling purposes.
If your delivery format is 1080p or a lower resolution and you are shooting at 5K or 4K switching to compression ratios such as 10:1 and 12:1 may be
desirable. Since you are scaling down your material from a higher captured resolution you can maintain a good balance between visual quality and receiving the added benefits of being able to role longer takes or holding more material on your REDMAG SSD media.
Just to add to this. The shooting notes that I added to the Red Quick Reference Guide came from my own tests for 4K and 2K delivery, stress testing REDCODE in extreme color/post workflows, and researching productions from the last year or so.

One note about The Master and Dark Knight Rise still lenses from earlier in the post...
This isn't a very good comparison to small sensor stuff like Red (I'm joking of course), but it's an issue with optics. A crappy lens in medium or large format or 65mm will out resolve the best, highest quality full frame or super-35 lenses any day.
