Please forgive this nub, but I will give all the settings. I think in the neutral grays the noise is totally unacceptable. We did a test in our studio and I didn't really notice it until I looked at the footage sent out of FCP.

Scene setup:

Scene Select: F1
Op Type: Film Camera
Rec Format: ph1080/24p
VFR: Off
Detail: -2
V Detail: -2
Detail Cor: +2
Chroma Lvl: -3
Chroma Phase: -2
Gamma: B.Press
Knee: Low
Matrix: Norm1
SkintoneDTL: Off

Panny: f7.6 @1/60 iso 640 wb= auto from gray card

I brought the footage in via Log & Transfer.

Here are the samples:
1st raw video transfered
2nd raw video in FCP
3rd output video
4th final video settings

The only filters used in FCS were Levels and Color Correct 3 way, neither were very severe adjustments.

Here are the export settings:

Thanks for the help!

 
How did the footage look on the HD monitor direct from the camera in the studio?


I see that you applied filters such as sharpening. Why sharpen a grey card? (curious)

That is a screen grab from the bg while I was setting up. the test was two talking heads. It looked soft(still with noise) the first time I exported the video, so the second time I added a level 2 sharpness(which for some reason reads as 5 in the window.)

maybe I am just being overly critical, but I think the amount of noise(which I can see in the file before any work is done) is unacceptable. I used 3200w of lights for the two talking heads and I was still at iso640 but that is partially because the 14-140 is slower than my grandmother. *sigh
 
It's not noise you see. That's the limitations of 8bit and some compression artifacts. Yes converting to prores does help a little before CC. This is most noticeable in areas of light gradation. Adding some grain/noise can hide this.
 
Also try recording images instead of a gray scale. Also look at the imagery at the point of playback from the camera to a HD monitor and compare that to the Apple monitor.

Best,

Jan
