New RED Firmware Brings In-Camera LUTs & Zone System Exposure Tool

RED Gio Scope Zone System Exposure Tool
"Why does this look so washed out?" "Don't worry, it won't look like that later."

No longer will you need to have this conversation when working with RED and viewing in RAW mode. Being able to view a log output on your monitor is helpful to see what's really there in your exposure, but the consequence has been that those who don't understand log tend to think something is wrong with the image, or worse, they actually start to like the ungraded log and want it as the final product. In RED's new 5.3.9 Beta firmware, this will no longer be an issue:

RED's also got a new exposure tool that works just like the zone system, but instead of using a light meter and working out your f-stops in your head or on a piece of paper, you'll be able to see each stop of latitude expressed as a color on-screen. This new mode, called the Gio Scope Tool, was developed with the help of actor Giovanni Ribisi, who has been working with RED cameras for some time:

Here are the other significant changes in this 5.3.9 Beta firmware:

  • Switchblade UI rich menus
  • 4K Broadcast Module support
  • Independent monitor LUTs
  • ACES proxy view
  • Gio Scope (Zone View) exposure tool
  • Simplified menu support on REDMOTE
  • Lift Gamma Gain (LGG) controls
  • In-camera curve editor
  • Full height 3:2 format
  • RCP API 6.0 support
  • Fujinon Cabrio button support

They also dropped a release build, version 5.2.29, which fixed:

  • On-camera REDmote upgrade
  • HDRx in 6K HD at max frame rate
  • 512GB MINI-MAG reported as "not a REDMAG"
  • Loss of Nikon lens mount iris control
  • Camera freeze with 4K Broadcast and +1 Adaptor
  • Dragon intermittent startup errors
  • Invalid Dragon formats in spinner after loading custom Epic preset file
  • Text in Media Info dialog
  • Anamorphic selection in Format dialog for Scarlet Dragon
  • OLPF description for Dragon Monochrome
  • UI when last user cal map is deleted
  • Monitor initialization entering playback
  • "N/A" in Power Out status dialog for +1 adaptor on startup
  • Stale battery info when battery is switched on Quickplate module
  • Reverse key action for AE: Increase/Decrease EV Offset
  • Minimum f-stop with Sigma 18-35 for Canon
  • Adaptive Preview Quiet Record mode dialog in UI and RCP
  • Intermittent detection of Switchblade on startup
  • Motion Mount ND setting not saved across camera power cycle
  • Side Handle indicating -1 % on startup
  • Detection of Nikon Nikkor 17-35mm f/2.8 lens
  • Updated in-camera help files

In addition an Alpha driver and firmware for RED ROCKET-X was released which adds:

  • Up to 20% speed improvement
  • Added support for Mysterium-X & Dragon Monochrome
  • Stability improvements

And a Alpha 31.1 for REDCINE-X PRO :

  • Added: Rocket-X Monochrome support.
  • Added: Support for AJA Io 4K and Kona 4 (Note: removes support for Kona 3).
  • Note: Rocket-X support requires driver and firmware
  • Fixed: Issue with OpenEXR upscaled exports when using CUDA.
  • Fixed: Issue with QuickTime mono audio layout exports.
  • Fixed: Issue with Avid external audio exports.

The Alpha builds aren't that stable yet, but if you desperately need a feature that has been released, it's there for you to try. The Beta firmware for the cameras should still be pretty stable, though the release build will be the most stable.

I was digging on reduser on the recon thread and there's a question about it. The answer from red team was a bit misleading. Actually I couldn't decipher the answer. The guy that asked didn't get it also. lol

The zone system and lut in-camera would be a must for us MX users. I know it's a EOL product, but who knows?

You could always just use a lightmeter.

I'm a RED One MX user as a hurry I just use the color view (predator mode) or the exposure mode (under exposure is purple, over exposure is red, normal ranges are black&white)...but I just meter most of the time and don't even look at their tools.

I Shot with this build this weekend so we could use a custom LUT for our lighting monitor on a short film. We ended up having problems with the clips hanging up after cutting and having to do a battery pull every once in a while. We reverted to the previous build and it corrected the problem. Not sure if anyone else was having an issue like this. We were on a RED Epic MX.

That's not actually the zone system, which operates in terms of stops of light, not steps of latitude; as in doubling the footcandles to achieve a stop of light. Zone 5 should be 18% gray.
