  • 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 :)

Offering Postpro skills - RED footage denoising service

Robert, for HDR you have to export from RED Cine two different footages with different ISO settings and then combine both in After Effects on a 32bpp comp?

Is that your procedure?

Done.

All the discussion on denoising and some of the off-topic back and forth has all been moved to here: http://reduser.net/forum/showthread.php?t=27668

In this forum, it's about offering jobs, services, equipment. Please don't hijack or crap in other peoples' threads. Anyone who feels the need to offer alternative or competitive products or services should start their own thread offering such.

Answer for Ryan and Impagliazzo:

The procedure is quite simple:

* Export footage with ISO 160 (or whichever ISO gives you the most highlight details) and with ISO1280 or even ISO2000 (eventually give the curve a small toe in the highlights and a small shoulder in the darks - like 100/90 and 0/5).

* Import both into After Effects, project settings to 32bpp.

* High-ISO footage below and low-ISO above comp.
* Set low-ISO layer layer transfer mode to "Add"
* check your brightest highlight in the info palette - it might have values about 1.8 or higher (anything above 1.0 is superwhite and looks clipped)
* create adjustment layer
* apply effects/utilities/HDR compander
* set HDR compander to "compress range" and the "Gain" to a value a little above the values you checked in the info pallete - e.g. 1.88
* play with HDR compander "Gamma" to retain the brightness

HDR will always look a bit dull unless you put some s-shaped curve onto it.

Hope that helps, otherwise just ask when you get stuck in the workflow. :)

Brilliant, thanks! I'm looking forward to seeing the HDR in motion. The technique I have been using (PhotoMatix) has been producing image flicker that I do not like. This sounds like a much more solid way of processing the footage.
 
Concerning the HDR, as the data is contained in the R3D and not using a double exposure technique couldn't you achieve such a result tweaking a good curve?

Yes, you could use a single footage approach too, but I found tweaking curves could not deliver the same good results.
Thing is, that it makes a difference if you are using a curve to increase the brightness or if you are using the ISO settings.
The curve only approach makes the footage looking very unnaturally to me.
I will soon post another example footage.

Sorry Pat, yepp - the little interruption did quite irritate me - so I forgot to answer you. Thanks for the reminder.

Thing is it needs a lot of experience and know-how to find the right approach to noise reduction because each situation is different and therefore it can't be made automatic. Every new footage is a new challenge.
So it is not the like having just a plugin and pressing some buttons.
My care is towards minimal loss of resolution and details and this is what eats up a lot of my time - the manual tweaking.

I think Robert may have done a good job but this is not the place to market. If he wants to share his technique great, otherwise, move on.

Not sure what peoples problem is? It's posted in Jobs/Equipment for hire - what is not clearer then that?????

Hi Robert. How much time do you need for denoise 2k File of 1 minute in DPX?
and what computer?
