1DX II Noise at ISO 100

Recommended Posts

I have been noticing quite a bit of noise in the shadows when filmed at ISO 100. Not entirely sure how much of it is from my color grading (Made LUT from Lightroom). I see some noise when lifting shadows before grading, but not nearly as much. I have a feeling I might just be hitting the limits of 8-bit, but I sometimes see a ton of noise in untouched 120p 1080 footage. Not sure if there might be something up with my camera, I didn't notice any noise before. I will end up using neat video or something of the sort soon. 

Here is a quick video I just put together; you can see it when watching in 4k on a monitor when it is a headshot.

Thanks for looking at it. I barely brought back any shadows in some of these clips. I have a video on Alcatraz, where inside the prison, there are a few scenes that are perfectly exposed (no post adjust), yet the areas of the scene that are just barely darker have a lot of noise.

In those cases, it might be best to give more exposure and pull the shadows down in post. The image will be cleaner.

That's what I did on my Sony when shooting LOG. I found many pros mention to not clip highlights with the 1DX; footage does have a harder time coming back from over exposure than under. I usually expose a tiny bit brighter than what my final correction will be in post. Really wish they had put CLOG in this, I tried the fake ones & I couldn't pull the blacks back down to what I would like to see. Feels like there is IQ loss with the ones I tested vs a neutral canon profile (btw, I shot this on the faithful profile with contrast/sharpening all the way down & -2 saturation)

I am wondering if it is because there is no internal NR on the camera when in video mode (just noticed this)

I didn’t know that either... that’s a good thing, though. If I were you, I would ditch Faithful and try Prolost Neutral settings. Is this mostly happening in 120p with 1/240 shutter? Are you using the in camera meter to judge exposure?

I tried cinestyle & marvels, but not prolost yet. It is happening in all recording modes. I always have my shutter st double my framerate. I tested tons of different exposures & looked at them in post; they all had a decent amount of noise in any area that had shadows in person. It's very odd because I had ran tests when first receiving the camera & I couldn't even see any noise at various settings/lighting conditions.
