FS5: FS5 New Owner fighting noise

I'm a new owner of an FS5, I've only really shot on Canon DSLRs before, so I'm on a steep learning curve! I've bought Doug's vimeo tutorial and started watching, it's great. Today I set up the camera outside and took a short clip of some shady trees, going through each picture profile. I was shooting in HD XAVC 25fps. I then imported these into FCPX. I'm disappointed with the noise levels, especially using the Slog profiles. I then took a couple of shots using my Video Assist via SDI Out, which look much cleaner in FCPX. Can I get a cleaner signal in camera?
 
Speaking from experience with the fs7: noise can be a concern if you are using the lower(darker) stops of the log curves(slog2/3). What this means is that Slog capture around 14 stops of dynamic range and some of those stops are not as clean as the others, but you still have them if you really need them. What you also gain shooting in slog is the ability to wrangle colour in a pretty flexible way in post.

So my advice to you if you want to shoot log: learn how to use LUTs. Learn how you can crush those noisy stops if you need to and how you might need to expose a bit for that when you shoot. Set zebras and use waveform to confidently "overexpose" the image a bit.

The benefits of learning the above is that you up the general quality these cameras are capable of. For lowlight shooting get a speedbooster, fast 35mm lens and some LED panels :)
 
Thanks, I've taken the camera into the studio, and got better results. I shot a still life on PP9 and overexposed it. Then brought the clip into Resolve and corrected the exposure, and added a 3D LUT - the SLog3Gamut3.CineToSLog2-709 one. This has got me a nice clean result.
So much to learn... feeling like I've jumped down a horribly deep rabbit hole.
 
You dont need to know everything now. Just learn the most popular workflow first: shoot slog3 with sgamut3.cine and apply the LUT called LC709A.

Try that as a start. Get comfortable with that LUT, try to add some green (or remove some magenta) and some warmth on top of that. See if you like the results.
