Scarlet X Data Sheet

[Phil Holland]

**updated 12.12.2012



Red Quick Reference Guide (RQRG for short)
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!)

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

It is currently 52MB. Here is the permanent download link:

I needed to make a Scarlet X Data Sheet. I do this sort of thing for damn near every camera I use. Thought it would be useful for others.

It contains:
- graphical crop factor image for each Red standard recording format
- recording times in minutes on 64GB and 128GB SSDs for 24fps at 4k with maximum quality compression ratios
- max fps for each format with and without HDRx
- relative to FF35 crop factor chart with common focal lengths that should be useful for those who purchased the Canon, Nikon, or Leica mounts

I'll attempt to keep it updated as Scarlet X's feature set and firmware receive updates.

Scarlet X Data Sheet
This data sheet was designed to be a quick reference card for the Scarlet X equipped with the Mysterium X sensor. If you would like to see the Epic version it can be found here: Epic X & M Data Sheet

Red Format Key
This is a key to the different Red capture formats. It contains the format name, max fps, resolution, and aspect ratio. I've included both Epic and Scarlet information on the same key; hopefully useful to those using Epic and Scarlet in A/B cam situations.

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.

Red Mysterium X Crop Factors and Common Aspect Ratios
The following three graphics pertain to framing.

This graphic shows the cropping effect of the different recording formats on a sample image:



Taking that concept a bit further we can see the effect of the different formats and crops on the field of view:



This graphic shows common motion picture aspect ratios and how they can be extracted from the full frame of the 1.9:1 aspect ratio of the Mysterium X sensor through vertical and horizontal cropping.

General Usage Notes:


Notes on Black Shading from this thread

Proper Black Shading Technique
1) Attach the Red Body Cap to your lens mount and secure the cap with the locking collar on the mount.
2) Place your camera in a dark place or cover your camera with opaque fabric. Do not cover the vents.
3) Power up the camera. A/C Power is preferred. Black shading currently takes over 20 minutes.
4) Wait for the camera to come up to operating temperature. Usually takes 10 to 15 minutes.
5) Set your shutter speed to suite the project that you are shooting.
6) Begin your Black Shading Calibration.

After it completes you may want to verify things are okay. Leave the Red Body Cap on and crank the ISO up to 12800 and make sure your focus assist tools are turned off. What you are looking for is an even black field. If for some reason it is not, likely light has some how leaked in.

My recommendation is to blackshade:
1) upgrading to new firmware
2) big ambient temperature changes
3) long exposure times (longer than ~1/15th sec)
4) very short exposure times (shorter than around ~1/1000th)
5) beginning of a project
6) as often as you feel like

Remember to black shade at default after long/short exposure black shade when your finished.

More convenient/flexible black shading coming later.

Black shading is really only required when there are changes in sensor temperature or for long shutter speeds. It is a good idea to let the camera come up to temp before black shading.

Black shading (Default) is good for most situations, including high speed.

Black shading (Current FPS/Exposure) is intended for slow frame rates and long shutter speeds.

Also, if you look at the system configuration screen.. the sensor temperature and shutter speed is shown for your user calibration.

RedVolt, RedBrick, and General Battery Consumption

- RedVolt (30Wh) provide about 30-35 minutes of operation time. *
- RedBricks (140Wh) provide around 2.25 hours of operation time. *

* tests done with the 5.0 LCD Touch and Side Handle attached.

What we can take from this is that you get about a bit over 1 minute per 1 watt-hour on battery power. **

**Red has stated that "power management will be coming to the firmware" in the future which should only improve battery life. Also to note, that RedVolt XL batteries (90Wh) are on their way to be used in the QuadVolt Module.

Camera Temperature Guidelines and Warnings

The camera will shut down for temperature reasons. Below is the behavior you should get when reaching high temperatures.
At 72c the temperature display will turn yellow
At 74c it turns orange
At 75c the user speed is overridden and fan goes to max speed. Even if recording.
At 76c the temp display will turn red. Although max fan speed usually prevents getting there.
At 77c if you are recording, the record will be stopped
At 83c the camera will shutdown

Hey Phil,

Thankyou, very generous of you to share it. I'm sure there'll be many people on this forum that appreciate you sharing! :-)

[Joost de jonge]

Great information.

Thanks for the effort.

[Sergio Perez]

Thanks. Really appreciated!

[Josef Gatti]

Perfect info, really appreciate it.

Looks like it might be difficult shooting at 2k, ha.

[Sergio Perez]

This is why I dream for a 4/3rds mount, a "c" mount and a Nikon 1 mount for the Scarlet :) . The Nikon 1 camera and its lenses now actually suit for something :)

[AJ Aguirre]

BAAAADASS, thank you thank you

[johannperry]

Many thanks, very useful info

[Demetri Zuev]

Awesome!

Now if only Jarred would give us info on different aspect ratios that are available at different resolutions.

[Stefan Antonescu]

Thanks a lot Phil !

This should be a sticky...
