They pretty clearly didn't- "fx3/a7s3 sensor vs. A7iv sensor" obviously acknowledges the FX3 and A7sIII are the same.

I'm guessing the new processing is less, well, processor-intensive. Cruder algorithms, easier to compress... something, that reduces processing overhead and makes room for the additional AF processing (without paying for a much faster chip). Or maybe image processing is in a separate chip but they switched to a cheaper off-the-shelf part that was designed for cellphones.
Whatever it is, they can call it a new "Leica look engine" or whatever they want, but that's just the specific shade of marketing lipstick they're putting on this pig. Somehow I doubt Leica would want to move towards an oversharpened cellphone look, if anything I would think they would want the opposite.

Wow thanks@PannySVHS! Never thought my stuff would be brought up here.
The S5IIX, to be honest I haven't been shooting much this year so not a ton of time with it yet, but a bit of a mixed bag so far. Love the new AF, the intraframe codecs are nice to have as my stuff has so much motion in it. Other than that it's mostly the same as my S1, which was/is great (other than the AF). On the negative side, my X has had a problem with looseness and glitching in the mic jack since I got it. Wasn't bad at first as I customized my cage to put a little bit of pressure on the plug, which worked for a while, but now it's gotten worse and I have it boxed up to go to Panasonic for repair. I'm not a fan of the new processing for the linear profiles, I shoot entirely in V-Log so it actually doesn't affect me, but... gross, looks like cellphone footage. I'm eagerly awaiting the S1Hii or S1X or whatever comes next, but they'd better fix that processing.
The piece you posted was almost entirely Cine-D, a couple of V-Log L shots from when there was that "hack" to install it on the GH4 for free- and I'm glad I didn't just pony up for the official upgrade, because I couldn't get around banding in the sky (you can really see this in the shot at 0:17, and it's not just YouTube's compression), would have been a waste of money. For post I just used the Leeming Cine-D LUT, and then his "Rich Velvet" Quickie (look) LUT, pulled back a bit. I liked the density and saturation this gave me, reminded me of some HVX200/HPX170 stuff that I'd seen years ago. Past that just some selective Neat-ing and a bit of unsharp mask. I appreciate you noting the detailed/not oversharp look, that's what I've always gone for.
Lenses, for fisheyes the GH4 had a cheap "manybrand" (Samyang/Bower/Rokinon etc) 8mm f3.5, on a 0.64x Metabones BMCC booster that the shutter would crash into if triggered so I had to remember to WB with a different lens. Then on the G85 I had the native-mount manybrand 7.5mm f3.5, much easier to work with, smaller/lighter/cheaper/sharper, but not as wide of a FOV. The booster/8mm shots are the ones with the slight vignetting in the corners. For regular lenses it was about half adapted Minolta MD/MC stuff, no booster as I couldn't find an affordable one that didn't flare/blue dot like crazy, and half Nikkors on a Metabones 0.71x booster. No Panasonic lenses as I couldn't get good results with manual focus or AF.
Thanks @kye, the truth is that I really struggle with editing and rely heavily on beat/music/rhythm for structure and flow. So that means a lot. The B-roll shots are actually a bit sparser in this piece than usual, this is a reaction on my part to so many other video profiles of female rollerbladers often being padded out with too much slo-mo, B-roll, and second/third angles of tricks, usually to cover for a lack of clips of actual tricks. Chynna is arguably the best in the world at this style of skating so I wanted this to be a bit more "all killer no filler"- 35 tricks in 4 minutes- typically the better men in the sport will have about 25-35 tricks in this length, while the aforementioned female pieces have 15-20, plus plenty of slomo of them tying their hair up and putting their skates/helmets on 😄

I agree, I want the NR setting since the beginning =).

Interesting, Panasonic should lower the 12-35mm price now.
