I don't know Christoffer. I asked a friend of mine who works on Nucoda system and he just confirmed with attached screen shot.

Hello!

Does anyone here know the VFX Workflow with IPP2?
I wanted to try it out just now but the exported EXRs are interpreted like this in DaVinci, Fusion and Preview:

At first, I thought it might be the color space and typed in the primaries in Fusion, but that didn't help either.
Also, I tried exporting an ACES EXR — it came out the same way. I used the current Beta Version of RCX.

Robin, can you provide a single frame R3D and send to Graeme?

I was just about to ask that! Yes please - frame and description of what you did and I'll get it to the RC-X team to look at.

In the meantime, can you try the release version (non-beta) of REDCine-X and see how it works?

Hey,
so the release version also does strange things during the export:

Didn't expect this... As it doesn't seem to be a workflow issue I'll pm you the details, Graeme.

Send me the EXR please. I can compare with reference decode from your R3D.

Make sure "Post : Image : Effect" -> "Film Look" is disabled.

Hey guys, about to start prepping a feature which will be shooting 2x Weapon Dragon 6K's. Do I have the ability to pull up RWG + L3G10 in camera w/ 709 output to monitors, or is that only available on Helium? If not what should I set the legacy color to in camera that will bring me closest for an IPP2 post pipeline?

 

[Ben Scott]

You can use one of the provided luts (including rec709 with various rolloff options) for output on top of l3g10/rwg.

FWIW, I've been using the RGW/L3G12 and IPP2 Preview LUT via DaVinci Resolve to Epic Dragon (not Weapon) footage on set and I am amazed at how well the neutral colors come up looking perfectly balanced. Just a few tone/contrast adjustments and it's as close to a perfect primary grade as I've ever been able to get from any Red camera.

I'm an Epic Dragon owner and I'm not going to upgrade to Helium - so unless these settings get into a future build (unlikely I think) for Dragon, I'll have to settle for using a RG3/RG4 LUT in camera and changing to the IPP2 pipeline in post grading, but I'm very impressed with IPP2 at this point.

hi,

i just received my new epic-w and was watching the "upgrade your workflow with ipp2 pipeline" videos on the main red site. http://www.red.com/news/upgrade-your-workflow-with-ipp2-reds-new-image-processing-pipeline

it says there's an image drop-down menu, and a change in the menu in general, but this is not the case with my system. i've checked the firmware, and it's up to date.... so where is this new menu? and specifically the "image" menu option. i found some changes i can make in the "video" menu, but why is that different from what these videos are saying... which says it should be in the "image" menu.

thanks,
- dan

Where do I get reds LUT for the IPP2 for redcineX?

Good grief that's a load of LUT's. I shudder at the thought of having to scroll through that entire list as a dropdown menu in RX or Resolve. Are there a few of these that are basic to IPP2 that could be the one's placed inside the LUT folder for easier selection?

I'm assuming that Gamma22 is 2.2 and Gamma24 is 2.4, Gamma26 is 2.6, HDR is clear but I don't get the inclusion of BT1886 since it's an older CRT calibration standard gamma.

 

[Graeme Nattress]

With the REC709 standard you get an OETF, but there's no explicitly defined EOTF, rather there's the assumption you're viewing on a broadcast monitor. To address that problem monitors were measured and thus we get the BT1886 EOTF which is gamma 2.4. So as IPP2 asks you to tell the system the gamma of the monitor you're viewing on, for SDR, BT1886 would be usually correct.

Thanks for the clarification Graeme, is it common then to go ahead and load all of these LUT's into RX & Resolve, or if you are mostly working in REC709 output are there a more select number of choices?

 

[Graeme Nattress]

I'd just load up what you're going to use. You may want to experiment first in the beta of REDCine-X to see what rolloff and contrast options you like. If you're just grading to a 709 display, just load up that colour space and BT1886 on the gamma and you're good to go. If at a later date you need REC2020 or HDR, just swap in the new LUT and you're in a great shape to do some final tweaks before output.

Hello from Blackmagic Micro Cinema Camera world. I used Cineon Log (same curve as used in old RED Log) as my Timeline Log curve for BMMCC RAW footage for a while. I like the contrast response it produces without any additional adjustments. Some time ago i experiment shadows recovery from underexposed images to get wide dynamic range images. As a Log to Rec compression i usually used custom LUTs generated in LUTCalc but with Davinci Resolve 14 Color Space Transform Tool now allow clipless compression of color space and gamma.
So i ended up that boosting Expose and than lowering Gain produces exact same result as need. It keeps highlights unchanged and recovers information from deepest shadows. So i have up to 6 additional stops of slightly nosy dynamic range.
During tests with difefrent Log curves i noticed that Cineon irretrievably clips highlights after such huge expose boosts and it can not be recovered by lowering Gain. So it seems it is just a natural limitation of Cineon which was actually was designed as a Film response curve but not a HDR editing curve.

Just to compare this s how the image looks with Expose boosted to 5 without Gain adjustment
