Scene Files - Noise vs. No Noise

I've found a setting that seems to work for me, but the more I read posts about people actually preferring some noisier settings for the sake of the codec and 8-bit, the more I tend to agree. A little more noise in-camera before compression can definitely help with banding and other things significantly, but too much obviously can be a bad thing.

What kind of settings are you guys using who prefer this? Also, I've said in other threads that Barry's book says the Cine gammas are the ones more susceptible to the uneven channels in the clipping (yellow highlights for instance) so how do you handle that? I've been told that the complete opposite is true by editman. I really prefer using the Knee setting so the Cine gammas seem like they're out of the question for me. Obviously you should always watch exposure, but I do like the Knees ability to roll things off more nicely when you don't have much choice.

Cine-D is the noisiest gamma and stretches things quite a bit. I really like how B.Press gives me a look I want in-camera, without me having to do a ton of contrast adjustments in post, but B.Press is also the cleanest gamma. Perhaps Cine-D is a good option if I can do without Knee, and simply drop the Master Ped a little to get something close to B.Press while inducing some more noise into the picture?

Everyone has settings for their own uses, but I'm interested in the settings of those who think a little noise can actually help. For the record, I tend to add my own grain to the image afterwards, but just as with 35mm Adapters, a little bit of grain (or noise) before the camera compresses the image can actually be favorable and make things a tad more organic.

Thoughts?

My Typical Settings:
Detail -7
V Detail -7
Coring -7
Chroma -3 to -4 or so
Gamma B.Press
Knee Mid
 
These are the settings I use and they work well for me. They match up very well with my EXcams profiles, and my 5DmkII settings. And they are as banding free as I can get the AF100. I normally do some grading on every shot, mostly add contrast. But I don't like the idea of having to change the shots too much. I should also mention that I use the NanoFlash pretty much full time on the AF100.

When I started to look on how the noise came out with different settings I basically took a 1:1 output from the HDMI feed pointed at black and different colours to see what could be done to reduce noise. My finding was that Cine V together with the Fluo matrix gave me the least amount on noise. Using Norm2 has a bit less noise in black but much more in blue and it smears black more than Fluo does.

Next I looked on how banding could be reduced and a bit of noise seamed to be a good thing. That's why I'm using Norm1 as it has some noise but not to much. Still it helps to reduce banding.

Then I started to dig into what could be done to reduce the yellow fringe some highlight areas have. Comparing the different gammas I found both Cine gammas to give me the best result. So I came back to Cine V as it also has less noise. I did this by shooting at a very clipped light, that gave me a yellow fringe or halo around the light, and looked at what I liked the best out of the gammas. I also compared how my 5DmkII handle the same scene.

I couldn't take away all of this yellow thing in camera but discovered there are filters in the CS5 suit that can reduce these to hopefully something one can live with. Applying a highlight limiter set to around 100% takes away much of the yellow and leaves only blown white areas which is fine in most cases.

I've ended up with a couple of settings like; Clean, 5DmkII, Sharp and Flat, that form a palette to use. I know these will give me very nice images with my AF101 each time and now that I've tested how to squeeze the juice out of the camera I really don't have to worry so much anymore.
 
My base settings below - but they have a tendency to change. This has low noise at 800iso, I wouldnt say completely free.

Detail Level -4
V Detail Level -3
Detail Coring +2
Chroma Level -4
Master Pedestal 0
Gamma BPress
Knee (variable as it depends entirely what I might be shooting)
Matrix NORM2
 
I'm with you man. At first I wanted a nice soft, noise-free, image. But now i'm finding that i want to introduce a little more noise to break up the posterization. I prefer noisier image to an image with gradations running along walls, skin, etc..

So right now I'm using:

Detail Level -4
V Detail Level -4
Detail Coring -1
Chroma Level -3
Master Pedestal 0
Gamma CineD
Matrix NORM1 or CINE
 
I bought this camera because I wanted my images to pop. Playing with some of these recommended settings, I've been a little disappointed...
Then I went the other way. Now I'm VERY happy. I started shooting a music video today. I just looked at my footage. My guys and I was like HELL YEAH!!

My settings:

Detail Level +5
V Detail Level +5
Detail Coring -1
Chroma Level -5
Master Ped 0
DRS 1
Gamma Cine V
Matrix Cine

When I'm done with the video, I'll post it.

Here are a couple of screen grabs, straight out of the cam.
