Fuji GFX 100 ProRes RAW?

Recommended Posts

The Fuji GFX 100 along with the Panasonic S1H is the most advanced mirrorless camera for video on the market at the moment. There are reports today that Fujifilm are working on a big firmware update for the GFX 100, with ProRes RAW on the list of features.

It'll mostly likely be heavily subsampled to maintain Fuji's no crop philosophy.

Internal recording uses 11604 x 4352 oversampling which exceeds HDMI 2.0 bandwidth and obviously Atomos Ninja V's processing power.

quote from your blog;

"What is interesting about this is where will Fuji draw the line? Will the X-T4 get it? Will it be internally recorded on the GFX 100 to high-speed UHS-II SD card? I doubt it, but we can dream".

Probably the best dream after the rumor of Samsung NX-2

Fingers crossed. Let dream come tru!

Is it Quad Bayer?

The actual 4K recording on my cards from the GFX 100 doesn't really look like 11K oversampled.

It looks more like a modern pixel binning technique. It's a bit above the A7R IV but not as detailed as an X-T4 and there's some aliasing.

So I doubt it is doing an 11K sensor output.

Fuji once did a presentation on "their best solution for 4K" from the GFX 100's sensor. And it had a quad bayer pixel mix going on.

If it does have 11K RAW video in the buffer before it gets downsampled on the image processor... I am sure it could be downsampled while remaining RAW data. Just as there are medium and small RAW stills options.

11K horizontally yes, vertically 2/3 lineskipped.

That presentation was about an X-Trans version of the GFX100 sensor, which was designed with 3 x 3 colour aware binning. But that project has since been shelved.

Yes the sensor will have to be heavily subsampled for ProRes RAW. It can’t send 11K RAW.

Isn't internal/external recording more an issue with Prores Raw licensing than with the camera's ability to do so or not? 

Not sure if this has been officially stated anywhere but I highly suspect the reason Panasonic made a partnership with Atomos was because the latter carries the license burden.  So I would imaging Fujifilm taking a similar approach or else it might have to be a paid upgrade to offset the cost of licensing. 

Canon, on the other hand, is able to offer internal raw on the R5 so matter-of-factly because they have their own Cinema Raw codecs.

I have shot this video using GFX100. Autofocus in video and lack of slowmotion in 4k are drawbacks. but  image and handling are better in GFX100 than Xt-3. I wish they really add better Phase-detecting system and add full frame 4k 60fps.

Better highlight retention or low light?

Yes the autofocus is pretty, erm, shall we say... Hybrid. Somewhere between contrast detect AF and phase. It hunts. Not sure why. It's extremely unreliable in video mode. 32-64mm zoom has internal stepping motor, silent, fast, but the camera does not make the most of it. The X-T4 is far better for AF. Some lenses like the 63mm f2.8 are incredibly bad on the GFX cameras and it's not much better on the GFX 100 with phase-detect AF on sensor. I am hoping for a firmware update that dramatically improves it as I can see no good reason why it has to be so bad! Reminds me of the X-Pro 1!!

Apart from that, it's my favourite all-round camera right now. Love it.

You can put a £20 lens on it and it still looks like medium format. So cinematic.

Andrew,

Wow, I was going to reply to a thread on dpreview linking this thread for them to read, however they ban EOSHD links?

I was actually trying to help them, however if they want to continue such highbrow stupidity...:

My censored reply to a lot of confused dpreview thread entries below:

>>>  Re: GFX 100 may become a monster video camera ....

FYI...

Wow, this website bans EOSHD URL listing.
Stupid and lame...

There are a lot more GFX 100 threads in the EOSHD forum.

I have actually learned a lot from the EOSHD site, as for the past many years shooting videos of my families life events.

Yeah, regarding Prores Raw licencing, I read somewhere about implementation of PRORES RAW internally in MAVO edge 8K camera, whether there were any issues regarding patents. Kinefinity replied that "Patents are restricted to US but not in other countries and we don't sell any products in US."
