The problem surfaced again in the newest video of the guy who posted the fix, and he told me the fix was unfortunately temporary, he's thinking about sending his A7III back.

@frontfocus Hi, did you have time to check this?

I just packed away my pitchfork and put out my torch. Your detective skills are far more effective.

My cat disagrees.

Fuji already gives you Eterna, I built my own LUTs for the rest. They are created for the X-T2, but they seem to work with the X-H1 as well. Remember to switch your clips to video range, that's what the LUTs expect.

4K 16bit uncompressed RAW at 25 fps needs 422 MB/s. That's megabytes, not megabits. Based on the information we've been given so far the body can handle that, but you can't write that to the SD card, the fastest UHS-II cards can write up to 250-260MB/s continuosly. So you either compress RAW, or lower the number of bits.

It's great isn't it? :D

@mkabi He said earlier in this thread that it's internal, that why we discussed UHS-II capabilities.

Unfortunately it doesn't work all the time. I had only one hot pixel on my X-T2, but I could not remove it with the built in remapping function. Tried it multiple times.

Oh I didn't know you have to do this procedure for a pixel remapping. On my X-T2 there was a menu called pixel mapping, so it was kinda obvious.

That was fast. If that's a true fix, that's one of the weirdest I've ever seen.

If you already own an A7III, you might want to check for this, the guy says he noticed it in different owners test shots as well:

Long but informative review:

This is just talk, noone is rushing anything. I don't even have an NX1 I for one trust Arikhan that he won't come here when he needs to be left alone. That's what I would do.

@Arikhan So the sensor is capable of capturing 28MP at 240fps, and the processor is capable of compressing and formatting it realtime. That's awesome, but we are talking about uncompressed RAW video right? Like Magic Lantern. I'm a bit confused now, because my question is still unanswered. If we have something like Magic Lantern RAW, but with 4K, how do you write that massive amount of data to an UHS-II card?

I believe the speculations ended with the conclusion that you are only limited by card speed. Did we get at least that part right?

Okay, it seems like we all come to the same conclusion after all. Now we only have to wait and see.

But that was my conclusion earlier and Arikhan said I was completely wrong.

Yeah I get this and this is fine, but last time I checked the bitrate of 4K 12/14bit uncompressed RAW at 25fps exceeded the maximum continuous write speed of the fastest UHS-II cards. How do you solve that bottleneck?

Well he didn't say this Monday. I like the cat.

Yeah, the A7III is a steal :D

I'm still interested if 1080p60 has worse quality on the X-H1 than on the X-T2, if anyone can test that. (There was a test earlier in this topic that showed significantly more moiré on the X-H1.)

Oh that's not my video, I don't have an X-H1 (yet?).

So in order to have working AF, don't use DR400 (or 200), don't use F-Log, and don't use a fixed ISO. And even then the transition is not smooth at all.

Well, if you can truly record 4K uncompressed RAW at 25 fps in 12 or 14 bits, internally, that will indeed prove me wrong. If that happens, it will make a lot of people happy, myself included. Keep in mind though that I didn't make up things like bus speed or uncompressed raw bitrate requirements, so saying that I'm completely wrong without any facts is a bit meh. Prove me wrong for real
