  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

REDgamma3/REDcolor3 support for the Red-One MX camera

I was just about to start a thread similar to this today!

I hope the new firmware is not that far away. I am having EPIC/REDMX shots where monitoring both cameras at the same time has everyone scratching their heads.

We need RC3/RG3 for our REDS!
 
We're looking in to this. It's not as easy as it sounds, unfortunately. We'll keep everybody updated!
 
Sure hope you can squeeze this in - it would be quite a treat to be able to show "on set" an approximation of what we will get in post...
 
I think I understand the difficulties RED is having implementing this. The circuitry involved in the two cameras is different, despite having the same sensor inside, so I'm sure this presents some challenges to the engineers. Some experimentation of shooting with R1 and then processing in RC3/RG3 until you are confident in the results is probably the best strategy right now. RED has pulled off other miracles before, so don't want to say never...
 
And once you've figured that all out, try to find a way to put the Dragon sensor into our RED Ones!

Ummm , isn't this easy to do with a 3d lut , folks?
I mean, come on. From the previous version it's a slight S curve, and basically some saturation in some of the reds.
A 24x24x24 should be plenty to capture all the nuances of the 'color science' of redgamma 3.
3d Luts are a cinch to make in Nuke.
Maybe I'm misunderstanding peoples needs. Any serious color correction software package supports 3d luts on media import.

Well, my guess is that the issue is not whether it can be implemented as a 3d lut or not, the issue is how to implement the lut in hardware, in realtime.

I've never seen the circuitry of the RED One so I can't tell how it does what it does, my guess is they have some sort of FPGA that does the lut, maybe in the way of a transfer function that expresses the curve they want to achieve. Using FPGAs probably gives them the ability to reprogram the circuit with a simple firmware update, and run at realtime speed, without burning that much power.

But then, there is a limit in terms of what you can do, and the complexity of what you can achieve in realtime in those circuits. There is also the memory issue and backwards compatibility. Maybe making room for RC3 would imply removing something from the FPGA to make space for it.

Who knows. Only the RED team knows what are the challenges ahead. I would just say that the camera is not quite a general purpose computer that can just run any mathematical function in realtime, so comparing it with Nuke is not a fair comparison.
 
I see, you are worried about the LCD image/video outputs having the new color as well.
Otherwise, the new color look is just a meta data tag in the file, with no extra in camera processing.
 
no chance for Dragon-sensor upgrade, no redgamma3/redcolor3 options, we were alone, there is no option to step up........Welcome to the MX-club!

Ouch...

That's about the silliest thing I have read in a while. If it is such a burden, I can help you out with your camera...
