Noise and Grain
Hey Everyone,
i’m currently using the Canon EOS 5D Mark II, and trying to set up a shoot. I have been watching videos, reading up, and just generally trying to get the most out of the DSLR. I downloaded and installed the Cinestyle settings for the camera, did some still test shots and got the color grading down to how I like it. However, when I went to the set and did a few video test shots, I came back only to find out that no matter what F-stop or iso i am at, I am just getting an excessive amount of noise/grain from using Cinestyle. I tried doing a lens cap test with iso settings to confirm it was Cinestyle settings that was causing the noise/gran.
I was wondering if there is something I am doing wrong, or a way I can remove the grain in post w/o spending alot of plugins? I would love to use Cinestyle, but won’t be able to if I can’t solve the noise/gran issue as it makes my footage un usable at all combinations of f-stops and iso. Thanks in advance.

forgot to add in; should I keep using Cinestyle, switch to standard, or something else? Thanks again.

How are you post processing the h.264? Are you? What are you editing in. My work flow is to use 5DtoRBG Batch. There is a free version from the Mac app store called 5DtoRGB as well. This is on a Mac. I process to ProRes422 and have not experienced any noise with the Cinestyle setting.
I only shoot at ISO 160, 3204, 640, or 1280.
Unfortunately, I don’t know your work flow.

As far as ISO levels, I started out by stay to the same levels you are using, but the more tests I did, the more I noticed the noise was showing up no matter the level. I even went as far as making a chart of F-stops and ISO levels and just taking 5 sec clips at every combination of them. As far as work flow goes, I usually just import the footage into FCP (Log and Transfer), which it then converts it to pro res 422. However, The noise is bad enough that I can see it even on the DSLRs LCD screen, even at low levels of ISO / f-sop. I have also tried pulling the footage directly from the card and dropping it into After Effects.

Are you lighting? or just going with available lights. Not enough light will cause noise in the blacks Heat can also be an issue and of course it cold be a bad chip/sensor. Can you rent a 5D Mark II and do a side by side comparison? If the rental doesn’t exhibit the problem, and yours does, it might be time for service.
