SDR-Matters Matter - Give Them A New Home In HDR10-Space

0, 
Amazing HDR videos surely impress us with lifelike  scenes which again only the modern camcorder can afford. 
In the past golden years, we did many shootings that hold our family or journey with big emotion. 
Emotions in Small/Standard Dynamic Range!
Can we retrieve/remix them into the HDR10 space? - Yes!! 
But not via dogmatic book-teaching. 

1, 
To make HDR videos we'd better own one or two display panels that can be activated in Windows10 and checked with 10bit color depth in GPU-driver.

2, 
Use and set the videoscopes as follows - they provide huge help when you Bee confused with your eyes.

2.1,
Take the ruler in this scale, it's all-purpose assured.

2.2, 
Even if you don't produce 5.1-Surround soundtrack, this format keeps your sudden rage back when you import materials containing that thing.

And 4 extra audio busses make the Mixing Console more flexible.

2.3, 
Struggling how the video part should be?
Please check --
I, go UHD resolution, or fullHD if you are very nostalgic. 
II, go progressive scan, forget the interlacing techno. 
III, go HDR10 Mode; Vegaspro takes the rest from working environment till render template for you.
IV, enable this to prevent clips with double streams which could occupy or create unexpected timeline. 
V, confirm these 2 items as you see. For why or how, you yourself must find out, not me. 
VI, enable the HDR-Preview button.

3, 
So, that means we've finished our cuttings and come now do color correction. 
(The SDR-Materials shown here are from website and, mainly, this forum.)

Project Mediapool, select all Matters and change their color space to Rec.709. 
The color space list will be mostly understood as LUT filters. 
They are not! 


3.1, 
The ACES2065 (so called AP0, Vegaspro's default HDR-Space) covers all color spectrum we human can see (the locus or horseshoe form). 
Thus, it defines every colorspace (including the LOGarithmus spaces) as its own primaries. 
That is to say, the max value RGB and their positions will not be calculated/transferred with reference matrix. 

They are directly "put" into their "Stammtisch" (their regulars' table).
That's why you are not allowed using the (imitated) Look-Up-Table once again.


3.2, 
Now let's take a look at the Rec.709-Assignment of our SDR-Matters. In theory, they should sit there perfectly. 
First sight, everything seems OK.

3.3, 
Second sight, the assignment is too royal, so that the illegal colors of Rec.709 are all out of control. 
(If you don't understand what "illegal" here does mean, forget it) 
illustr.-illegalcolors


3.4, 
The assignment clamps the SDR-Matter deadly in Rec.709, so that any adjusting will become chaos. 
Let's try using the filter ColorBalance (set RedMidtone=-0.100) and see how illegal colors break your dream to pieces.

4, 
Cogito, ergo sum!
Every definition is man-made definition. When the Rec.709 breaks down, why don't I break through.  
If I can't make another Rec.809/909, I surely can find out one that scales the Rec.709's RGB-Primaries not only in a controllable dimension, but also correctly. 
I did: ARRI-Linear - ALEXA Wide Gamut

4.1,
As the SDR-Matters have finally a new home, the rest is easy to take. 
Here you go - thanks a lot.

So you are saying that instead of using REC 709 as the color space, you assign ARRI-Linear - ALEXA Wide Gamut instead to SDR media when used in a HDR project?

Do you do the same with photos?

Yes.

I am rendering HDR right now and required tremendous computing power. Last yrs I bought a BenQ 27" HDR monitor for testing HDR video. Since then I removed from my desk and use my 32" 10 bit monitor for Photos/video. I am now have a pretty good idea how I grade my HDR on SDR monitor and the results is I like it.

I don't remember exactly what model of the 32" but I do remembered it is the BenQ high end model with 100% RGB gamut. With limited desk space on this specific work area I can not have dual monitor, hence the removed of the hdr one. I love the 32" BenQ for color accuracy love the 32: size.
