RELEASED: BETA REDAlert! (v1.5.5)

[Deanan]

Always a pleasure to help...
We'll also be able to have other types of LUT outputs from the QT component like REDlog and PDlog.

How do I setup Qmaster so I can queue shots off?

 

[Andreas Herzog]

Hello. I am investigating setting up a render farm, and playing with QMaster. As I understand it, to have QMaster do Red Alert jobs, it will use the command line interface. When I try the "QMaster interface" on the render screen, nothing happens when I click submit. I haven't been able to understand how to tie it all together. Could you point me in the right direction?

 

[Deanan]

Do you have the name of the cluster in the "cluster name" box?

 

[Andreas Herzog]

I changed the name from "Red cluster" to "red_cluster" and it worked.

btw Deanan... you are my GOD!

 

[Andreas Herzog]

Deanan, will RedAlert render DNxHD in the future?

Deanan, will RedAlert render DNxHD in the future?

Glad you got it working!

Yes to DNxHD. Working on the implementation details now.
It's a bit tricky to support the details properly.

Red Alert v1.56 BETA

Red Alert v1.56 BETA

Hi folks.
I've spent a couple of days examining some test footage for a feature looking for an optimal extraction method, initially using Redcine on PC (8 proc), and to compare the various denoise, debayer etc settings in RedAlert I've jumped onto an 8proc Mac (fairly new box, Leopard & all the goodies) and tried a bunch of settings to generate DPX frames at 2k 2:1 from a 4k 2:1 .r3d.
I had the RedAlert upgraded to latest v1.56 before starting this.

What I found is that the ONLY setting variation out of Denoise, Debayer & OLPF that made a difference to the image was changing OLPF.???

In the meantime I've bought a new Macbook Pro (2.5GHz, 4mb RAM, GeForce 8600M GT) and loaded RedAlert onto it, and repeated the tests today.
Same results...
altering Denoise settings made no difference
altering Debayer settings made no difference
altering OLPF settings made no difference between Off & Low, but did alter the image between Low & Medium, and Medium & High (started getting some nasty highlight-edge contrast artefacts above the low setting).
Also found that Medium setting of OLPF puts a 1 pixel border of NG pixels along the top & left-hand side of the image.
I'm working at default settings on all values (ISO320, exp -0.4, 5600K etc) and REDLOG output to DPX, then comparing images (including individual colour channels) at about 400% magnification.

I generated a TIFF file (2K also) just to make sure it wasn't a DPX related problem, but no difference between the DPX and TIFF)

Thoughts?
Chris

Spent much more time looking into this on some various shots... seems the various settings are working :turned: , I just couldn't see a lot of what was happening on a night shot I was playing with, because much of the changes are extremely subtle.

RedAlert
OLPF - noticed some very fine artefacts being created on HIGH setting, so I'm looking at using a MEDIUM setting for this at best, or possibly OFF.
DEBAYER - very subtle differences, but I can't see a reason (at the moment) not to use HIGH.
DENOISE - don't like what any setting is doing to the Red channel, particularly on skintones and hair, so leaving this OFF, however......

RedCine
I think RedAlert is outputting a more useful image for VFX work, but I prefer the way the NR handles the Blue channel in RC. I think Graham N. said its a Chroma de-moire, which is different to RedAlert's DENOISE function.

Might try to mix back the Blue channel from a RC output to the R&G channels from RA to see if it gives a better result... ( cue a compositor...)

Come on NAB announcements!
