The 1080p mode on the GH5 is really quite good; if like me, you are happy with a dense 2K image, then 1080p offers the most bitrate saturated options in the camera (no affect on color)
Cine-D has a slight bit depth density edge over VLog, while VLog has a slight extreme gamut edge. With 8 bit, Cine-D is decidedly better
Great work Parker and Benjamin! Alas, I've got to get the next update out..
Just finished writing one last tool that I believe will be critical for automating camera support, to do the Exp Pres (it is the fourth 'sub-section' of the ECE)

@Sage might have better info on this, but from my experience, the 1080 out of camera vs 4K downscaled to 1080 in post are nearly identical, something very rarely found. I shoot 4K for most projects still as I have the processing capabilities and want to future proof. But if you aren't concerned about it, 1080 is very wonderful out of the GH5. On the advantage side, 1080 out of the GH5 gives 60p in 10 bit, and a more bang for your buck bitrate. I've been using this GHAlex process for quite some time now, and couldn't be happier with it. I feel like it gave the GH5 the soul it was missing.

From a promo I did recently with the GHA color on the interviews, you have to skip in a bit to see them:
 
Funny thing, I was in a meeting a little while back with the Director of a really big TV station in the States and was showing him a video I did using the GHA color, while watching it he turning to me and asked under his breath, "you shoot on Red, right?" I took it as a really big compliment I must say😉
 
 
 
 
 
 
 
 
 
 

I'm just finishing up a project right now, shot on the S1 and GH5, using GHAlex, turned out quite nice. (These are just low res grabs from frame.io) 

 

@mercer The thing I always notice about GHAlex compared to other luts is how it just adds a nice sort of clear separation to the skin tones, in both color and b&w. It just adds a midtone pop that I really like. 

XT3 is in the plans, indeed. At this moment, its down to documenting the process of adding a camera to the server, and then streamlining the Pdf writing process as best I can (later today). This will make a camera cycle as efficient as possible.
From the LogC alone, V4 isn't that different from V3 for the average image. When saturation becomes more extreme, V4 is quite a bit better (much, much more accurate to Alexa). And when using V4 on unintended formats (i.e. Rec709 footage), V4 holds up, while V3 doesn't. Here is a comparison with one of the more saturated images I've got (most notable shift), using Soft (most equivalent variation between 3 & 4):

Crazy as it sounds, that's a possibility. My main concern there is bit depth density; SLog would probably not be the focus. The GH5S is next around the corner

Hehe, no idea there

Thanks dude.
I am curious as to Arri's obsession with cows and bunnies?

These are quite good, reference samples from every current model:

I am going to build a directory of Alexa files for people to download and play with.
Any helpful submissions very welcome.
Or pointers to existing file downloads online.

That's the plan - I'm almost finished setting everything up for cameras going forward. I will really be able to accelerate now; a good indication will be how fast the GH5S is supported after the release of V4 for GH5. If a matter of weeks, then that is a very good sign for other cameras. Things will accelerate from there.

Hi @Sage any chance you working on S1H Vlog? Id love to have some Alexa colour 😁

I believe he may have used Emotive on the Ursa portions; he is a huge fan of GHa and has P4Ka as of 3 weeks ago. The rolloff on the sunny leaves etc. feels right, but the colors are very off and green; its a safe bet that the Ursa has quite a different color science than the P4K, and will need its own conversion (working towards that day)

If you are seeing this cat...

Then it means the move to the new server has worked for you.
Good news. No more cats.
Bad news. No more cats?
EOSHD now lives in the cloud. Faster speeds no matter where you are on Earth.
Please let me know if you see any bugs.

Its not too much a concern; in fact, HLG/Cine-D are more robust from a codec perspective. Speaking Gen.4, the extreme gamut is perhaps where VLog will have the slight edge in directness, but the others might be preferable overall.
Attila - It does include perceptual luma weightings of RGB. To revisit the earlier discussion, everything fell into place with the engine rewrite (Pt.2). I've been working on the web side this week, and mostly wrapped that today. Now its back to finishing GHa V4, and last the Pdf (and streamlining it for future cameras).

Attila does great work, he has an excellent grasp of the technical; highly recommended
That 4K 60 sounds quite good (super-sampled 10 bit)
Ironically, I've still been working away at the EC engine, and fixing copious bugs (its inevitable that when I think a thing is finished, the work has just begun ) That being said, I think today I've fully tested it, and everything is working really, really well.
This is a GHa Tungsten LogC render from this morning; the wheels on the far left and right are completely theoretical extreme gamut, beyond what the camera can record - the ones in the center are actual log gamut (and V3 for comparison):
