Analyzing first footage

Hey everyone,

Been a long time follower of the forums and decided to make an account since I finally received my camera in the mail.

For the most part, I am stunned by about 95% of the images that the camera has taken. However, I came a cross something that I know has been discussed to death on the boards, however I haven't found an answer for it just yet; noise.

I find that the camera produces and unnecessary amount of noise in the mid/dark shadows. I have calibrated my camera based off of the many things I have read in this forum:

Lens: Canon EF 50mm f/1.2 L
Nanoflash recording @ 220 mbps
1080/24p
Film Cam
Detail = -7
V Detail = -7
Detail Coring - 4
Chroma +2
Chroma Phase +2
Gamma = Cinelike-V
Matric = Norm 2

I am uploading my test footage onto vimeo as we speak and will post the link to it once it is processed; however, until that point, I was wondering if anyone would mind giving some insight onto the possibilities for the noise?

Leave the coring to at least 0 and don't use the Nanoflash. It will record more noise but will mask banding issues.
 
I would definitely turn down the chroma to -2 or less.
And try not using cine gamma.
Just do some experimentation.

This is what I am currently using:
Film Cam
Detail Level -4
V Detail Level -4
Detail Coring -3
Chroma Level +2
Master Pedestal -2
Gamma HD NORM
Knee LOW
Matrix NORM2

Interesting Olof, I keep experimenting with other gammas but keep returning to Cine-D most of the time. It requires a little more post work, but seems to give me the best image to work with. Occasionally using HDNOrm, but I'd say 90% has been Cine-D.

That is one of my go-to settings.

The higher bit rates will capture more detail. The internal AVCHD recording will have less noise due to compression oddly enough. Hey but you get 4:2:2 color with the Nano :)

Ah, touché. Yea, I mean it depends on the settings. I'll give the above settings a definite shot. Like I said, it's only in a small portion of the images, but it is something I want to try and neutralize as best I can.

To TornFusion:

What bgundu says is spot on. I have two major setting saved in my camera, one for recording the native codec, and one for an external recorder such as the Nanoflash. The noise to banding tolerance is quite a bit different between the internal recording and SDI/HDMI output. With the right settings when going the external route and I can still get the image cleaner than I could with my HPX170. Experiment, experiment, experiment. The settings in the AF100 need to be tweaked substantially to get the best image possible where as my HPX170 was pretty close right out of the box, but if you take the time it is well worth it.

Thank you for the input!

My test footage finally loaded onto vimeo and, I must say, it looks completely fine when it's compressed; however, it obviously won't always be that way! :)
 
Hmmm, I thought to prevent premature chroma clipping it was recommended to lower the chroma value?
