Pocket 4K to Alexa Conversion

[Sage]

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):

Excited to finally get V4 for GH5S. Thanks for all the hard work.

Wow, what a difference in the V4, in the middle ones too! Can't wait to get my hands dirty! 

[GabrielFF]

All of this just makes me really excited for the X-T3 version!! Any estimates on when that one comes out? It's a really popular camera that really needs some of your help

I intend to support the XT-3 directly this year, sooner rather than later.

So that may actually fix the dark and lifeless reds I've had? Anyway, looks like a great improvement. :)

can't wait for the release either... Just got an OLED TV that i want to calibrate tonight. the new GHa release comes at the perfect time!

[Sage]

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):

Will the S1/S1H support be coming soon?

Here's some Pocket 6K footage.

How does this LUT compare to the @Juan Melara 's LUT? And then how do they compare to the powergrade?

[Sage]

He has done an excellent job of matching color spaces solely using color tools. A 3x3 matrix is kind of like a uniform accordion of R,G & B space, the cleanest tool for the job. The unique advantages to this approach are its tweak-ability, and that it won't clip boundary data in Resolve if you place a grade before the powergrade (grade after though; preserve core logc)

[anonim]

What a honest and noble behavior - not just to admit similar quality, but also to further explain it. Hat down, sir.

You are right, and you are a gentleman, because you didn't mention, that for ultimate precision your LUT is still the way to go. A matrix can get you close when you're lucky, but to transform all the color tweaks of a manufacturer, a 3D LUT is still the way to go.

I could use some quick help.

I have just started using Resolve, basically for the first time. Fluent in Premiere, but complete and total novice in Resolve. 

I imported some clips and they looked as expected. Did a quick sync and edit. Then imported @Sage's luts into Resolves folder. So, didn't do or add anything to the clip itself. Once I had brought the Luts into Resolve, my clip immediately changed. Not in the media browser, but in the timeline, and I think Master bin. I can't seem to turn this exposure or color correction off.

Thank you.

[Sage]

Hmm, that's a strange one. When a bug like this happens at project level, I often start a new project and import everything. One can export the timeline when it is highlighted in the project bin, through File > Export AAF, XML. That will often strip the timeline of project level bugs when re-importing to a new project.

And, place the whole EC folder into the Resolve folder, and refresh in Resolve (as compared to a single cube, etc). This way, you can have the ABLs and Exps in folder order right next to the conversions. Here's -.66 + Day Lin + Abl2:

The legend Sage. I'm guessing with the new update for gen 5 coming to the bmpcc4k, we are covered by your last update!

It does have Gen 5 support - I will be revisiting all G5 profiles after release to be sure that they are in line with the latest from BMD (along with a few other adjustments)
