Fuji X-H2S

Hopefully they release something this year before the competition catches up to the xh2s sensor 

 

Fuji also has a lot of meeting room space booked at NAB. Would love to be a fly on the wall there.

I analyzed the raw data in the DNG converted from ProRes RAW and now I know exactly how it's messed up.

I adjusted my tool and I think I have a working fix now. It fixes the raw data itself, so the result will be perfect in every software that reads DNG.

Before (see the broken line in the middle):

After:

 

I'm still testing my tool, it can read 12/16bit DNG, uncompressed, or lossless compressed, the lossy formats are not supported. It uses multiple threads, on my recent i7 laptop it converts with 25-35fps.
It's a pain to convert twice but at least I got it working, and learned a bit of C++ on the way.
If only I could fix the framerate issue as well, but no chance for that.

What about BRAW. Does it have the same half line shift issue in 6.2k?

Also in general: BRAW/Video Assist no alternative? What are the pros and cons vs prores raw atomos? Just different workflows?

I could only download one example which did not have it but I don't want to base my opinion on one example only. Does anyone have downloadable 6.2k BRAW from the X-H2s?
However people already confirmed to me that BRAW also has the stuttering issue so it's definitely a Fuji problem.

In general I would prefer ProRes RAW since it's true raw in a sense that it's needs the same processing as a common raw file after it's decompressed. BRAW seems to be more processed with slightly less color detail, but I believe you'll only see it when pixel peeping. The obvious difference is that BRAW works in Resolve, which is a big plus given how large these files are, it can be a pain to convert ProRes RAW.
But anyway both of them are unusable at the moment, I have a feeling that we only have raw for marketing reasons in this body. With the current issues and less DR it's garbage.

I'm fed up with Atomos, I wasted a huge amount of time doing tests for them for the stuttering issue in ProRes RAW. They didn't even try to replicate it. I reported the problem at the 8th of February, since then I provided tons of test material. And where are we now? They still think it's my unit, or my SSD or my HDMI cable even when I told them I tested with multiple units, multiple cables and SSDs. Unbelievable.
In the meantime some other guy asked BlackMagic about the same issue (so apparently this is related the the X-H2s), and they sent it to their engineering team right away, they reproduced it and notified Fujifilm about it. HUGE difference between the two supports. Seriously, even Fuji is better than Atomos, because they don't reply at all, so you won't waste your time with them 🙂

@Attila Bakos Sorry to hear that and it does sound like they are trying to deflect actual testing but if the problem comes from XH2S, then surely it isn't really Atomos's responsibility but rather Fuji's to provide a fix? In any case shame to hear RAW is pretty much unusable in this cam.. especially considering it is the only way to circumvent the heavy processing and Xtrans CFA issues.

Without testing it's hard to say who's responsibility it is 🙂 Of course now I know that it happens in the Video Assist as well, it's clear that it's Fuji's fault, but I didn't know that for a long time, neither did they, yet their effort was as low as possible.
