This is an important thing to call attention to. Its not like the Base Curve is early in the pipeline like it used to be and some people may still find ways to integrate it if they prefer the results…

Here my version in darktable. I don’t know how accurate the colors are, but they are pleasing (to me). Nice shot!

You can also use the profiles that capture one uses , they help in getting that punchy colorful look easier , specially with base curve.
But that profile blows out highlights quickly for me and i have issues getting them under control , so in the end i switched back to regular darktable scene referred and it’s built-in profile .
I might give it another try just to see if i learned something in the last few months

Dude, I even tried it, but as you can see in the image, when I use it, the photo is totally underexposed.
Add unbreak profile module and use the default gamma to check if that helps but there is an extra curve used with C1 this is why they can’t be used directly in general…
You might get some good info here and even some of the shared files might help…

Instead of trying so desperately to emulate C1, I really think you should first learn to use DT on it’s own terms, instead of fighting against it, so to speak. By messing around with base curves, colour profiles etc. when you barely know how to use DT, you risk always being disappointed and not getting the most out of it.
Here’s my attempt. I tried to make the colours punchy, without going too far. Since you haven’t shared the C1 jpeg, I don’t know how it compares to that.

I extracted it above from the raw file…
That’s the Sony jpeg, not what C1 will give you.
We can only know that with access to the C1 settings as there can be a combinations of curves and profiles applied by default in C1 and those have not been stated or provided I don’t think… The OP would have to provide that and of course as you say the exported jpg as most people don’t have capture one…the extracted one is just the Sony reference… but it serves as another data point for comparison of the DT and C1 “looks” created in the various posts for this image…
Honestly, I don’t care at all about the C1 settings. I’m not trying to replicate them in DT (which would be a fools errand in any case). I just want to know what the result looks like, so that I can try to replicate the look. For that a jpeg exported from C1 is needed - a screenshot isn’t really good enough.

I downloaded C1 trial…using the A6300 generic profile and the auto curve and the high contrast film curve you get these 2 jpg files…I didn’t make any edits or touch exposure…
I agree I would just use capture one if that is the look you like…
EDIT:
Setting the curve to Auto and the profile to the proicc version and hitting C1 auto correct produces this… It seems like it only changed a couple of settings to produce this but I could be wrong… So maybe this would be the C1 default ish… look…
Thanks. I’ll have a go at replicating them tomorrow.

I am talking about Capture One…the default curve is called auto. That is what I used…there are about 5 others including linear… the second curve was the third option… and the final image was basically the first one but C1 had an “Auto” correct feature like basic photo apps… So i applied that … So those are the 3 images… Sorry I don’t have access to C1 at the moment to post a screen shot but its pretty obvious… The various ins and outs are explained here… in case this is what you are asking??

Sorry, I completely misunderstood your message!
Anyway, I’ve tried to use the C1 input profile in darktable but I don’t get good results. I think the reason is that the unbreak input profile module has a non linear output and that invalidates somehow the rest of the pipeline, so that I get clipped highlights very fast.
Does somebody know if there is a proper way to use a 3dr party input profile in darktable? Maybe using the tone equalizer module right after the input color profile module instead of the unbreak input profile? I will try it out later…
In Capture one there are 2 curves applied please see this link How to create Capture One profile
See my edits it is very close to the Capture One default as shown by Todd Prior

I have the same problem. Would be glad to read an explanation why this happens 
That’s what i said earlier.
Also, the profile is meant to fix extreme highlights by bringing them to white , while dt tried to preserve colors as long as possible .
Also, these profiles have a curve in them, or they expect a certain curve to be applied first. The 'unbreak profile ’ module is meant to give you something to toy with to get the profile more usable .
But it’s never going to be 100% usable , since the profile and the C1 pipeline go hand in hand , and its always going to be a struggle in every other raw software out there .
The same for Adobe dcp files . See the amount of toggles in rawtherapee , sometimes you really need to play with it to get to use them .
The DT profile works fine in DT, and with the quick and easy calibration tools in the 'color calibration ’ module I’m more than happy .

They are meant for capture one…Sure with a bunch of tweaking you might get something but the absolute easiest way is to just use the tools in DT. Use the profile there and fhen use the color calibration color checker feature to make an adjustment preset.
This should give you nice colors. Some ICC are valid over a reasonable range of lighting but many are not. Using an ICC blindly is just as much a penalty to the "scene referred workflow as many of the other things people worry about…
