Do This To Get Clean S-LOG 3 Footage | CINE EI Simplified

- Stopping down the cine ei value by 2 stops can help you achieve cleaner noise performance by using brighter lights or vnd to get the most dynamic range out of the dual base iso.
Remember that composition, white balance, and 1.7-2+ stops are just as important.

So here are your settings on CINE EI or FLEXIBLE ISO, because when I try to change the "exposure" of 2500 cine EI to 1250, I dont notice any difference. I have to film in a nightclub, I have the fx30 but I just cant deal with getting grain on my videos always
Flexible iso does not allow you to change the EI. EI only applies to Cine EI.
Flexible ISO would be better for you if you have to go above 2500. But keep in mind the noise performance.
This is where you have to determine if you will bring more lights to maintain base iso OR us noise reduction in post.
Cine EI just allows you to change the "exposure" of your viewfinder so that you can bring in the extra stop of light that you would bring down in post.
@Matthew_Chung Hey man, what exactly are you changing in terms of lighting since the exposure is "the same"?
I don't get how you are still capturing the data at 800 ISO yet the image is cleaner noise-wise when the metering, iris, and light source is the same and at the same level?
So, are you displaying your image darker by going down 2 stops [EI 400 from EI 800, for example], and increasing your light source intensity?
Yes!
Iso is still at 800 or 2500, depending on which one you use.
Cine EI allows you to "change" the exposure of your monitor to trick your camera to see more light. This is done by exposing brighter with your lights or reducing the nd.
Then, in post, you bring the exposure down by 2 stops. Like how you would over exposure slog 3 and bring down in post. Hope this clarifies!
So the trick is: for example, in CINE mode EI ISO 800, I lower the IE to 400ISO and add more light to expose +1.7 or +2.0, either using the aperture or adding more light sources. Is that so?
Yes. Changing EI is like "exposure" for your monitor/viewfinder. Therefore, in post, bring it down. 2 stops will get you that clean look that you are supposed to do for slog3. Over exposing 1.7/2.
Of course, it would depend on the scenario.
When you are filming outside, because it's brighter than indoors, typically you don't have to do this.
