It sucks when you buy into the latest technology only to wait years for the content to catch up and if you have an HDR display
You know exactly what that feels like
Obscure anime, old TV shows, cult classics, great movies the studio just didn't love enough
Forget about it. Now there are solutions to convert SDR to HDR like this one from AJA, but
$2,000? I could get an Archie X2060 for a tenth of that price on
eBay and according to NVIDIA it can do the same thing which means
They finally did it. What Intel and Microsoft failed to do 20 years ago
NVIDIA has given the home theater PC its killer app, but there's got to be some kind of catch
Okay, but does it spike power consumption like RTX super resolution? It's gotta look awful, right?
Is it full of artifacts like when DLSS first came out?
You're just gonna have to wait to find out Linus
Fine, can I at least tell them about our sponsor?
Okay
Pulseway, make remote monitoring and managing your IT systems easy with instant alerts auto remediation and real-time
Updates all from one platform any time any place on any device
Start your free trial today with the link down below. When NVIDIA recently announced their new NVIDIA app
We assumed that they would move the RTX video HDR toggle into that
Alongside the beta that now works with games, but instead no it is still buried in the old NVIDIA control panel
But the good news is that toggling it is as simple as click on click off
Ploof suggested we start with Wicked City an anime from 1987 that looks like it's from 1987
This is pretty little bit right dude. Anyway, that's not what we're here for
We want to see how our HDR toggle is going to impact the oh
Well, that really is something isn't it? Yeah
That flatness in the clouds in the sky
Yeah, it just gives it so much more way depth kind of brightens up the whole image, which I think looks good here
Yeah, it looks really flat without HDR and all of a sudden it's like you see more detail, too
Right, this won't be the last time we touch on this, but that may not be the artist's intent
That may be the artist's intent
But as a viewer, I know which one I would choose even I like this one better, too
And I tend to stick with artists intent right just like kind of a purist. This is even better. Okay, hold on a second
I haven't even toggled yet. But yeah, oh
the way that the night lights pop
Just looks kind of brighter and bluer here
It's lifting up some of the low lights which has the benefit of allowing us to see more details
But honestly in the bar scene, I feel like it's taking away from the mood a little bit
Yes, and that's kind of my issue with doing up mapping especially with some of these dark scenes
the original grade is
Smoky and hazy and kind of gloomy
Whereas this is is bright. It's very colorful. Yeah poppy next up
we've got Phil Tippett's mad god a stop-motion film from 2022 that suffers from the long night syndrome and
Doesn't have an HDR version at the moment
Okay
That is Wow those lightning flashes though with the HDR toggle on
huge difference first lightning flash and
Okay, it's on. Whoa
That's lightning. Now the color changed a lot here. Yeah, the background went to like a blood red
Yeah, I don't like that over saturation it changes the mood of that scene right it really does
However, the effects boy, does it ever make them pop? Oh, yeah, that looks good
So you can see you can really see when it toggles you don't even have to check it's like oh, yeah
Yeah
I just need every movie to have a proper HDR grade because it's clear even with this faux
HDR how it could look without HDR the specular highlights on us a slimy monster
They don't look like slime. They just look like I don't know smooth. Yeah, tell me this though
Okay, you've never seen the original grade. How pleasing is this to the eye? It's colorful
I like it
Do you like it? Well, I don't know what the heck's going on in the sea. I like the color. Oh
The highlights so much better. So good you can really make out that detail right in the center of those specular reflections
It looks like a shining light
We're off to a really great start aside from some minor quibbles about color saturation in the mood
There's no question that I would choose RTX video HDR over vanilla for everything. We've seen so far
Except
Everything we've seen is two pieces of content and none of it included live-action
here's the thing a compelling use case for this tech like with their RTX super resolution upscaling is
Streaming so whether you're watching someone game or drop expensive technology on your screen now
You can make just about everything pop a bit more
And as you're about to see it's not all sunshine and rainbows
Here's a recent video that we didn't upload an HDR or did we?
Wow, the sunlight linting off the garage door back there. Oh
Wow, it really messes up some things like white text. I
Mean, oh
Wow, oh wow
Some of this is okay. I mean these are people that I know obviously this is Maria and a llama day
It actually adds a little bit more life likeness to them
Like look at Maria particular. Oh, yeah. Yeah, like you can kind of make out the shape of her face a bit better
Right once it's turned on, you know
We were supposed to observe that with lighter skin tones
It gives a bit of a shiny greasy look but I guess I'm maybe not affected as much as some others looks
All right. I think it really just depends on how you see your skin is to be honest
Everyone is going a bit rosy and orange, but it's not
Like absurd it just looks a bit warmer dude overall. I think I just generally prefer it for this
Oh my god, look at her necklace. That's yellow. That's metal
You can just see like the specular reflections off of it like a lemon days ring pops more
Okay here. Yeah. Yeah. Look I'm right here. Yeah, so not HDR
Okay, HDR go again
Go again. Ooh
It's honestly not that different like I think your actual skin tone is right in between the two of them
I think you look a slightly paler in SDR and then slightly too
Oversaturated in HDR. So if we're gonna be inaccurate anyway, which of these images would you take? Oh, definitely HDR
All right. Let's find some sweaty greasy looking people here
You know what in this case?
Yeah, you're definitely getting a little bit more glisten
Just gives it a bit more depth. It doesn't feel in an unnatural way. Yeah
I mean, he's sweaty as hell and there's a ton of lights in that. Oh those lights just kind of
Yeah
I like it. It's a weird fall-off cuz you're going from like pure white to like the shine around it
That's what the court lines look like. I'll tell you that much. They don't look like that. Okay, the towels a bit much
Yeah, that's a shiny towel
Yeah, the court that's much actually look unnatural
Yeah, that's clearly not right if we weren't toggling back and forth and we weren't thinking about it
I would feel like those court lines. I'll have almost a reflective element to them
Yeah in person they don't honestly
The only thing that's standing out to me is that towel in the left corner that towels like unnaturally bright
God's towel. I like it
I just don't want to have to use the Plex web interface in order to enjoy it with my media library
so if this worked with the app or was built into the shield or something like
I'm ready right now. I'm mixed. I think watching it now
I've kind of grown into it, but I don't know
I still have to look at more things for me to like decide and it's gonna be the same for you
But what I will say is aside from some quirks it works pretty well
However, we haven't compared it to proper HDR mastering yet
Our reptile brains just being tricked by more brightness and color
Just like if we were shopping at a Best Buy to find out we're gonna use some of our own footage from my giant TV
Video I've been told that one of these files is HDR and the other is SDR
masquerading as HDR
using Nvidia's tool
That's fake. Oh
They're not gonna tell me yet
It's good
But it's fake. You're right. I know I'm right. Yeah in some ways the image is a little more pleasing but look at this
I'm pink
Whoops, it's too bad. I wanted it to be perfect
But obviously a properly graded piece of content is gonna pop where it's supposed to like this content behind me looks almost
identical
but is also going to retain the natural look of someone who is backlit and not for lit whereas
I'm just
Just lit. Why am I so flat flushing? It's like drinking
James looks better here though, and that's interesting is Nvidia making assumptions
through the selection of their training data
about
Properly lit people. So is this kind of like, you know
Taking the the studio mode of your selfie camera and applying it to any content that you watch
In fact now that I'm lit properly, it's far less noticeable. See in this dark shot. I look more
Lifelike whereas this is more reflective of the fact that I have no light on me
Damn, that is really close
This is a very impressive example. If I didn't know that that's a bit too much brown for my couches. I
Would probably take that image. You're right. It's very close. Like the display is like basically the exact same here
I actually think that the
Pinpoints on our light sources in the room look a little more convincing in the Nvidia version, of course
We're not using exactly the same display. So there is a little bit of variation there, but there's some banding here
It's like very little. Oh, you're right
Well spotted. I didn't see that. That's ugly. Oh
Wow
Interesting now that I know what I'm looking for
This is a much more egregious example of what Brandon just pointed out where that brighter object was clearly
Manipulated in a way that lost some of its original quality
Look at this
Compared to this there's a subtle difference in glow on the track for maybe the headlights
Is this I'm still very torn
Looks pretty good
Handled this white background
Actually really well. Yeah, I know it's in a video
They do a good job for the most part at recognizing when something's like a white screen and not like blowing it up
Some of these look more lifelike on the fake-o one
Which is very interesting
So how the heck are they doing this?
The first step is they expand the color gamut from s RGB to SC RGB
Using a transformation matrix. I can practically hear you saying SC RGB. I
Wasn't familiar with it either kind of a weird color space, but their use of it here makes a lot of sense
Just like it makes sense to go with a Honeywell PTM 7950 thermal pad for your next build now available for a reasonable price from
a reliable source lttstore.com
SC RGB is compatible with regular s RGB
But uses 16-bit floating point to calculate a massive dynamic range
Compared to 8-bit integer on s RGB all while using the same white and black points
So in total you end up with 281 trillion possible colors compared to the 16.7 million of s RGB
Now when I say possible colors, that's because we can't actually see a lot of them making SC RGB
Completely overkill for actually displaying anything
Modern panels don't have 16-bit control over their pixels let alone the ability to reproduce trillions of colors
But what it's great for is internal rendering and mathematical computation
So with that background in mind
RTX HDR kind of works like DLSS upscaling where Nvidia is taking an image
Blowing it up then using machine learning to fill in the gaps. It's the same idea here just with color and light
So to train their model they analyze a ton of content ideally in both HDR and SDR
Then they take that converted SC RGB frame
They apply their denoising algorithm
And then they convert it to BT 2100 HDR using that AI model to output a finished frame that
Brightens or dims specific spots in a scene or
Saturates colors to help them appear more vivid
ideally without it looking like a Best Buy demo. It's
Really cool. It also isn't really new
Windows 11 Auto HDR has been doing something kind of like this for SDR games for quite a while now
Often with decent results as long as you've completed Microsoft's calibration process
It's also been a thing on the Xbox Series X for a few years and it can really make those older games
Pop all of a sudden bright flashes are hitting about a thousand nits and they actually flash instead of just
Whiting at you. Of course all of this assumes that the display that you're using can reach that luminance level and display it accurately
I've complained a lot on this channel about the
HDR displays that are more like
HDR-ant because while their base is certified and they can interpret an HDR signal
Their backlight and panel technology just aren't good enough to make much of a difference compared to watching something in the SDR
With all of that out of the way then what about
Games where the competition is tighter for Nvidia's new hotness
To investigate we've grabbed a couple of the latest QD OLED panels and we've upgraded our modest home theater PC with a second near
Identical computer for our second monitor, by the way
We'll have links to all of this stuff down below if you're looking for PC parts or maybe a new monitor
Oh, look at that green that saturation on the green. Okay here. Let's look at shiny boy here. Oh, yeah yours looks so much better
Okay, hold on. Let me just clip. Oh, okay, or we can shoot this shiny. Oh, okay. Yeah
Well, the shine still looks good even with oh, come on. It still looks pretty decent. Yeah, it's all relative
I know decency is relative these fireballs from the imps not even close
What we're comparing right now is real HDR to SDR
But that's not what we're supposed to be comparing. Why don't you go ahead and turn on RTX HDR? Yeah, I
Can actually see the appeal of the RTX HDR version of this. Yeah, if you're into a really poppy contrasty look
It's great and guess what most people tend to prefer whether it's correct or not
I know they want brightness. They want contrast they want color and that's kind of what we're getting here. I honestly
I'd probably turn it on even here. I think it looks a little better than the
Actual native doom HDR setting. I mean the native doom HDR is pretty good, though
Pretty good, and that is really poppy though. It's fun. You know, yeah, there isn't a major impact on the
Visibility of dark region or anything like that. Okay
What's next?
Windows Auto HDR versus RTX HDR. Oh
Okay
This does not look very good. No, no, I agree
Yes, it just doesn't have that poppy contrast. It doesn't even look as good as the HDR implementation
Yeah, it doesn't like the Nvidia one is taking it even further. Yeah, this one is like not taking it as far
It's very dull like look at the
Candy that pops out of the enemies is not no glowy like this stuff looks okay the flashing but that looks decent in SDR
Anyway, yeah, this does not look a lot better than SDR to me if at all, right?
I don't think I would turn this on in this game. Anyway, it does make a lot of non HDR games pop a little more
especially games who never got like they're older like
2010 and earlier than that. For example, I play a lot of Dota with Windows HDR turned on. Yeah, and
Not much, you know, but when you like get the big and match accepted screen
there's like all these flashes of light and it looks pretty good, but
I'm gonna probably turn RTX HDR on at home. What's inconvenient? Is that every games?
Implementation is going to either be best with auto HDR or best with
RTX HDR or best with the games native HDR and switching between those
Oh
Yeah
There this took a while to get working perfectly right like some games for example
Don't allow you to calibrate the brightest point according to the capabilities of your display
I'm gonna end up with all these blown out clip to messes RTX HDR might be way better. Oh
That's fun. Oh
Oh
Man, it's such a small part of the scene, but it makes such a difference. It really does
Interesting in the okay. Okay. It's catching these lights on the little. Oh, yeah
Oh shoot. Oh balls forgot. This game is really hard. Yes
The muzzle flash is wild and those muscle flashes almost look like stormtrooper shots. Yeah, they're so bright
Oh
Okay, not gonna lie pretty cool it's actually really not that overdone either. No
And I cleaned off the water too. Yeah. Yeah. Yeah. What's that? I can't remember. I can't remember. I haven't played crisis in 15 years
But I
Keep expecting to like slide if I you know sprint and crouch it. No, no, man pre slide
There's the old game just like super resolution. This is pretty cool tech, but it comes at a cost
It doesn't use up nearly as much power as the upscaling tool
But it does consume a not insignificant amount and it's still in beta
So there are some bugbears for example
The video HDR doesn't work on DRM protected content at least not yet. And the game HDR doesn't work
If you have dual monitors at least not yet
I have a wild theory that Nvidia is basically waiting for Nintendo to launch the switch to
before they will launch the shield pro 2 and all of this software development is
Happening very rapidly right now because they're gearing up for the release of the shield pro 2
I mean think about it the original switch and the original shield pro should be very similar in terms of hardware and Nvidia has seemingly been
Due to release a successor to that damn thing for years and then with some of the recent advancements
We've seen RTX HDR super resolution. I
Can see the shield pro 2 being a killer box not just for watching video, right?
I mean, you know, obviously this is great for that but think about it for streaming games
Deblocking all those compression artifacts
Just
Converting to HDR on the local side so that they don't have to send all that additional information over your internet connection
I am excited and I'm also excited to see more solutions for using HDR displays
With content that doesn't necessarily natively support it
Even if it's not perfect today and hey back to what we were talking about before if I'm wrong about the shield pro 2
Maybe at long last the home theater PC will be a thing again and you will all rue the day
You mocked me for keeping my windows media center edition remote
Rue it I say
Just like you'll rue
