@Danne.
What are the dis/advantages of using Chroma Smoothing? I must have read something about it years ago, that it crushes details or something, because I've been avoiding it like the plague. Besides, if Chroma Smoothing is a fix for these issues and has no obvious caveats, shouldn't it be On as standard for every converter? For me, anything that destroys detail I avoid, especially on 5D3 because the perceived resolution is so small as is.
And how do I do FPN fix in mlv_dump? Do I need to make FPN Frames like Darkframes ?
@a1ex
Okey thank you, so its FPN. So now the silly questions. MLRawViewer manages to get rid of them with its vertical Stripe fix, but introduces artifacts like horizontal stripes and Chunky vertical stripes in black/dark spots and/or high contrast sources instead. Is it in anyway possible to combine the best of both worlds? It is my understanding that MLRawViewer uses OpenGL shaders with combination of different coding languages, ty @bouncyball, but it does a fine job at removing these vertical FPN except for generating other artifacts. Thoughts?
I find the exposure to be fine for my style, I like creamy soft highlight roll-offs and ETTR'ing too much usually ruins that, especially blowing out two channels, that is just not recoverable. This shot could have been +0.5 EV higher, maybe +1, that's a big maybe. But for my shooting style it's good enough. The shadows hold a lot of information underneath the noise, something Temporal NR is good at extracting. I just can't get rid of the FPN.

Or maybe I need to learn to Pull exposure better in post.
This FPN in the shadows was not a problem for me with this shooting style in Vanilla 24p 3x3 1080p. I think the sensor is pushed too much in 60p mode, introducing more FPN than normal. Just a hunch I have.
btw bit off topic, a line above in the link you posted:
The read noise can be isolated by taking a "black frame" image, an exposure with the lens cap on and the highest available shutter speed; there are thus no photons captured, and only the electronic noise from reading the sensor remains.
Is this the actual proper way of doing a Darkframe ? Setting shutter speed to the highest available?
And yet again, everything points to Darkframe+Flatframe for the ultimate image. But for any kind of production that is not possible as is, on Windows atleast. Its just way too much manual work, decompressing, sorting ISO's, sorting lenses, reprossesing for Darkframe+Flatframe, to me it just doesn't seem feasible. Not the Flatframe thing atleast. I have some Vintage lenses that have quite big variations in the Vignetting at the different F-stops, from 1.4 up to 5.6 and they are all Manual. Here's crossing fingers for Danne's venture in to Windows Darkframe automation.

As always, let me know what else I can help with.
