F-Log out of the box is not that pleasing (not to everyone at least), it has a green tint when compared to the in-camera profiles. I used the X-T2 + BM Video Assist 4K to create LUTs for F-Log that emulate the film simulations of the camera (at -2 shadows, -2 highlights, -4 color). I don't know how my LUTs will work with the X-H1, but I've found one of the sources that was used in the Slashcam test, and applied my LUTs to it. Although I can't tell you how accurate they are, I can see that we'll have some room to grade before the footage breaks.

F-Log + Astia LUT
F-Log + Classic Chrome LUT
F-Log + Pro Neg Hi LUT
F-Log + Pro Neg Std LUT
Since I emulate the flattest in-camera settings, you need to apply some contrast and maybe saturation.
 

X-H1 F-Log test:
 

Just asking, is there a chance that you interpreted HLG as video range in your NLE? My understanding is that it's full range, and it might look clipped when interpreted as video range, even though it is not.

I'm sure not many people shoot F-Log with the X-T2. I do, and in many cases the footage is unusable because of the noise in the red channel. Sometimes it's really bad, like the implementation is broken somehow. Now I downloaded some X-H1 F-Log footage from the photographyblog.com, and it seems that they solved this issue. This is big news for a few people, me included

I wish they added 4K60, but yeah, probably not gonna happen. I also wish for 10bit, internally or externally. I'm shooting F-Log with the X-T2 and with 8bit it leaves some to be desired. And I'm not sure if it's just my X-T2 or a general issue, but the camera gets hot relatively fast when you use HDMI out. And thermal noise appears after a few minutes at ISO 6400 and above, which you won't see when you only record internally. Oh and it would be great to have waveforms or rgb parade in video mode. And adjustable zebras.

I use the Video Assist 4K to record F-Log from the X-T2, and I really hope Fuji upgraded the implementation in the X-H1. The red channel is a mess, even the slightest grade can create pinkish blotches. And this is something you can't remove with noise reduction. I've worked with 8bit C-Log and 8bit S-Log2, and to my eyes they are cleaner. So yeah, 8bit can be enough, but it's certainly not enough for F-Log, not with the current implementation. It also has a very obvious green tint, so you have to deal with that too.

Well, in theory you could build a Cordova/Phonegap app where the index.html inside the app does nothing but a window.location.href redirection (as long as the target URL is whitelisted in the app). Then it would be the same as your app, and it could be compiled for other platforms too. I haven't tested it but I don't see why it wouldn't work.

Looks nice, I got good results from the image-adjustments panel. However it wasn't clear at first what the sliders do, maybe titles would help. Also you should be able to reset a single slider. I can't comment on the color matching yet, but it looks like it does it's job.

You can enable the highlight warning separately in the display custom settings, then it works in video mode too. But unfortunately you are correct about the RGB histogram, there is no way to show that in video mode.
I few weeks ago made a video about F-Log, you might find it helpful:
 
As you can see you can live without F-Log, and it's not without problems. I guess you would run into even more problems if it was recorded in-camera with 100Mbps H.264.

Exactly, and you don't really want to use F-Log with 8bit 4:2:0, I have found it to be unreliable even in 8bit 4:2:2 Prores. Sometimes even a simple S curve and a gamut conversion is enough to break it, I think it really needs 10bit, or some tweaking. Let's wait and see if the X-H1 gets it externally. My hopes are pretty low though.

It actually downsamples from a 5120 x 2880 area, it has a 1.17 crop.
