Epic M and X Data Sheet

[nigelsmith]

When I shot stills with a Hasselblad I knew a standard lens is a 90mm, when shooting S16 then it's a 15mm.

Is that a typo?
Because with S16mm 25mm is a "standard lens".

 

[Phil Holland]

am i right to assume there is no big difference between black shade calibrating at 96th and 48th of a second? and its only a difference when your calibrating at over 1000th of a second ?

It's been mentioned before that that particular different in shutter speed when it comes to black shading is minimal. I calibrate at 1/48th and shoot at 1/96th or even a bit higher with no issues. However, if you are going "way" faster or "way" slower I would highly recommend black shading.

What ever happened to 120fps at 5K? Wasn't that the spec? I know i've never done it, but I thought it was what was planned.

You can currently achieve 121fps with 5k WS. Full 5k 120fps is coming with the Dragon upgrade.

Is that a typo?
Because with S16mm 25mm is a "standard lens".

I'm a previous Hasselblad P25 owner and shooter. Somewhere between 80mm and 90mm gives you the "equivalent" FOV of a 50mm on FF35. However, that was always a bit off as the sensor was a bit more cropped than that. Generally speaking though on digital medium backs and bodies like that's what they say and it's often included as the stock lens.

In every film school out here in LA and my experience with S16 a 25mm is a standard lens as it achieves a similar 50mm FOV in relation to S35. However is standard means 25mm on S35 you'd bee looking at 13mm or if standard was say 32mm on S35, likely 16mm.

I created this in relation to S35 chart to help simplify that process if you come from a film background and don't like basing crop factors against FF35. It sometimes confuses people immensely, but you are looking to just maintain the same crop factor/FOV logic relative to wear you are starting from.

I should note, while these are accurate today, when Dragon becomes available all of these charts will need to be updated and the concept of what 4k is today on Red Epic and Scarlet cameras will change slightly.

Is that a typo?

Nonesence, however I know where you get that from! You have been told that with S16 it's half of 35mm which is about right. Standard lens for S35 is about 32mm.

The whole reason why I hate the crop factor is it just screws people up, it relates to FF35, not S35.

.

I suspect those film schools have not shot film for a very long time, 25mm is way too long for standard.

The standard lens set on 35mm film shoots over the last 30 years has ranged from 18 to 85, the middle lens happens to be a 32 or possibly a 35 with 2 wider & to longer lenses.
The 32/35 gives the closest FOV to a 50mm on a FF 35mm film camera.

 

[Phil Holland]

Yep.

 

[Jens Jakob Thorsen]

Standard lens

Standard lens

A standard lens means a lens that produces a FOV close to that of the human eye...Mr Williams is, as usual, correct...Except for the 6x6 format..its 80mm

More of a news update in case you missed it. Adobe Labs has released a new version of the Red Importer Plugin for CS6 and CS5.5.
http://labs.adobe.com/technologies/redepic_importer/

- Support for RedColor3, RedGamma3, and Magic Motion
- Removes the need to conform audio on Red files
- Stability fixes for large Red projects on a Mac

 

[Rocco Schult]

Hey, great collection of info, helps a lot.
Thanks Phil!

 

[Lee Saxon]

What is the point in relating to Still ftame photography? surely the reference for Cinema should be Acedamy frame which has been used in cinematography for 100 years or S35 which has been common for the last 20 years.

Because if you ask 10 different people the standard S35 size you'll get 10 different answers. This many perf, that many perf, blah blah blah. 36x24 is a known quantity.

Hello all! It's time for a big update to this thread and add some additional material.

I've been approached by several people and have been asked to compile the Data Sheets and my other Red notes into a book, ebook, app, etc. While that would help my "Get Phil an Epic/Dragon Fund" I would like these quick reference cards and general information to remain free for Red owners, shooters, and others to use. Here's what's new:


changeLog 10.29.2012

- added additional common rectilinear focal lengths to all charts.
- added additial information/definintions for each graphic.
- updated format names to reflect the latest firmware (QuadHD has been depreciated)
- updated graphic "Red MX Format Crop Factors" with all available resolutions.
- added "HD" and "WS" markers to the Data Sheet for available formats.
- updated crop factor algorithm and rounded up non-standard focal lengths.
- updated Data Sheets with exact 1K WS resolution (previously was guestimate prior to officail release).
- updated the formatting of the first post to be easier to find what you're looking for.
- removed Adobe Importer instructions as it is not needed with Production Premium CS6.
- removed 1K and phantom audio notes as they are now enabled.
- created Red Mysterium X Relative Crop Factor graphic with both 5K and 4K as base recording format.
- created RedMag Record Time (in minutes) graphic with updated approximate record times and the newer 48GB and 512GB magazine sizes.
- compiled notes into "Red Quick Guide" as a pdf file for you to download and/or print.​

Red Mysterium X Relative Crop Factors
This graphic sets the "relative crop factor" at 5K or 4K. The purpose is to assist the shooter on choosing their desired focal lengths when changing formats to produce a similar field of view from their main recording format. An example: You've decided on renting a 32mm prime lens for a shoot, but know you want to shoot some overcranked 2K material to match the approximate field of view. With this chart you can see that you would also want to rent a 16mm lens to produce the similar FOV and feel of 32mm at 4K.

RedMag Record Times
This graphic displays the recording times of all currently available recording formats and available RedMag capacities. I've listed the common production RedCode compression ratios from 3:1-12:1. Take note that the 48GB RedMag is designed for the current Scarlet X and it's max data rates. Currently we don't know how it performs on Epic.

All of this can now be found on the first post of this thread. Once I there is an official announcement regarding final Dragon specs I'll add them to this thread and publish new graphics.

Happy Halloween!

 

[Curt Pair]

Phil,

WOW! Please allow me to extend my sincerest thank you! I have a few new students hanging out with me these days, and this is PERFECT for them! Not a bad refresher for me either! Would you be willing to share the graphics on the crop factor and framing as a downloadable graphic too?

Truly spectacular work. I know this must have taken a ton of time to compile.

Many thanks. It's guys like you doing stuff like this that make this site worth it!

Humbly,

Curt

 

[Ketch Rossi]

What Curt said and then sum... Great work Phil.

 

[Michal M.]

Phil YOU ROCK!!!!!

 

[Phil Holland]

Thank you gentlemen. Curt your wish is my command.

changeLog 11.1.2012

- changed "Crop Factors: 50mm" graphic to "Crop Factors, Dimensions, and Diagonals" with more useful information.
- added format X/Y and diagonal coverage "Crop Factors, Dimensions, and Diagonals"
- created "Red Quick Reference Guide" (or "RQRG"); see below

Red Quick Reference Guide (RQRG)
I have compiled the bulk of these data sheets and some other useful operational notes into a PDF. After seeing my Data Sheets end up in rental houses out here in LA I was inspired to make something a bit more robust for new and seasoned Red shooters.

This PDF is suitable for printing at 300dpi on standard 8.5x11 paper in landscape orientation with space for binding. So you can print it out, bind it up, and toss a copy into your kit. (or email it to renter!) It is 14 pages long with a front and back cover as well as a table of contents.

Here's the current table of contents:

page 1 - Epic Data Sheet
page 2 - Scarlet Data Sheet
page 3 - Red Format Key
page 4 - Red MX Relative Crop Factors
page 5 - RedMag Record Time
page 6 - Red MX Crop Factors
page 7 - Common Motion Picture Aspect Ratios
page 8 - Crop Factors, Dimensions, and Diagonals *new
page 9 - Notes on Infrared Protection *new
page 10 - Powering the Epic and Scarlet *new
page 11 - Black Shading and Operating Temperature *new

I will be updating this as new firmware and upgrades effect the camera's functionality. Let me know if you have any thoughts. This is version 1, but I'll likely add camera and component measurements and weights to the next version.

This document is free and can be freely distributed, but is not for commercial resale use.

It is currently 46MB. Here is the permanent download link:
http://www.artbyphil.com/temp/redQuickReferenceGuide/RedQuickReferenceGuide.pdf

With a slew of new BT Scarlets out there and the extremely exciting Epic price drop I'm sure this will come in handy for a few people (including myself).

Enjoy,

Phil

Phil, “Great Work” as always! The (pdf.) file was sensational, can’t say enough good things about it! So was the Table of Contents!

[Boris Leonov]

Phil, thank you for incredible stuff! Although there is a typo I've noticed in resolution charts. (page 1 - Epic Data Sheet)

 

[Phil Holland]

Good catch Boris. I fixed both Data Sheets as well as the Red Mysterium X Crop Factors and uploaded a new RQRG pdf.

 

[Phil Holland]

Hope everybody had a good Thanksgiving break. I've added two new pages to the Red Quick Reference Guide that should be of use to people.

changeLog 11.26.2012

- created page "Monitoring Overview and LEMO Operation Notes"
- created page "F-Stop & ISO Reference & Flicker Free Shutter Speeds"
- added table of contents to first post of this thread
- corrected a few typos

Breakdown of the two new pages:

Monitoring Overview and LEMO Operation Notes - Covers the basics of the currently available Red Displays (LCDs and EVFS). Also, provides the general location of the port/socket and which modules have "dual" display support. There's a quick note on HD-SDI and HDMI too. Lastly there are instructions on how to properly operate the LEMO connectors. This should be particularly useful for renters and those new to the Red system.

F-Stop & ISO Reference & Flicker Free Shutter Speeds - Contains quick reference of Intermediate F-Stops (f/1-22) in both 1/3 and 1/4 stop increments. Also contains quick reference of ISO Sensitivities (50-102400) in 1/3 stop increments. Between this page and the ND Optical Densities found on the Infrared Protection page you have a nice reference to quickly identify how to tweak your image in stops based on your desired aperture and ISO. I've included two quick indexes of the Flicker Free Shutter Speeds (60Hz and 50Hz) for some of the more common frame rates. It's a nice guide for overcranked use, but also useful if you find yourself shooting with artificial lighting in a different country or find yourself concerned with NTSC/PAL standards.

I'm certainly excited by the tremendous response. It's been downloaded a whole bunch in the last month. Looking forward to adding more useful bits to it.

[Lee Saxon]

Excellent work, sir! I wish there was a way to tip you

As an OCD lunatic, I must mention two nits which are purely copy-editing

1.) on page 3, one title says "Epic M & X" while another says "Epic X + M" : different orders and different symbols. Personally I think "X & M" would mean "here's the X chart and the M chart" so since you're trying to say "here's one chart that applies to both" you're best going with "X / M"

2.) on page 13, "if you see any sort of gradient..." is asterisked as a footnote, but should probably be another bullet point like the others. In fact it should replace, "inspect the image," they're redundant.

 

[Phil Holland]

Thank you Lee. I updated the wording to be a bit more clear.

------

changeLog 12.12.2012

- created new cover graphic
- created "Audio, Timecode, and Genlock" page
- created "REDCODE RAW Primer" page
- changed wording on the Epic Data Sheet
- changed wording on Black Shading page
- changed wording on REDMAG Record Time page​

Happy "Twelve" day! It's been a couple weeks and I've created some new content and cleared up some wording in the RQRG.

Besides some updated wording, there's a new front page graphic. Also, there are two new pages that should be helpful to those who are new owners, renters, or even potential camera buyers. Here's what they are:

REDCODE RAW Primer - This is an important page for those who are new to shooting REDCODE RAW. There's some basic information on the codec, some of the advantages it presents, and most importantly some general advice for shooting to assist in creating high quality material.

Audio, Timecode, and Genlock - This page covers the various ways of getting audio, timecode, and genlock into your camera through the brain or use of modules. It also clearly states how many, what type, and what recommended cables you should use for your setup.

Here's the link: Red Quick Reference Guide (link to 52MB PDF)


This will probably be the last update before the holiday break. There's not too much more to add and this quick guide shouldn't get too thick. But I'll add Dragon info once we learn final specifications and a few other tidbits likely next year.
