Today, we are going to do an unboxing and review of the brand new Nvidia Titan RTX.
I will explain why the 24 GB Frame Buffer is a game changer for Memory bound application
like Adobe Premiere and Mistika VR.
I will compare the Titan RTX with my other graphics card - the Nvidia RTX 2080ti.
If you have your eyes on the Titan RTX and looking for an upgrade in 8K stereoscopic
VR video post-production.
This is the video for you.
Let's dive right in!
So the reason for my upgrade, if you follow my Instagram or facebook post, is I hit some
kind of bottleneck on my 8K editing pipeline.
I can't deliver cut on time to the clients which lead to angry producer and angry clients.
8K editing and effects in Adobe Premiere, After Effects or blender eats a ton of memory
b/c it's all cuda accelerated playback it happens to fall on the GPU.
So there are times where lots of immersive video filters or effects on my timeline, I'll
hit maximum memory allowance on the RTX card 11 gigabytes.
To make thing worst, with third-party overclocking RTX will crash your system when you run out
of frame buffer, which is the last thing you want.
Titan RTX is NOT for everyone tho.
If you are a VR gamer using the latest Oculus Rift S - you are not gonna benefit much from
the Titan RTX.
You better off stick to my other recommendation - the Nvidia RTX 2080 or 2080ti.
And if you are a serious VR gamer, well, you will also skip the Oculus Quest - the Oculus
Rift S will be a better upgrade for you to leverage the Power of your gaming PC.
Also, Titan RTX will not magically increase the playback and rendering speed of your current
system unless you have a PC to match its power.
To bring Titan RTX to its full potential, I ask Maingear to build me the PC dedicated
to 8K VR editing and post-production using Adobe Premiere and After Effects.
It is not a Gamer PC but a powerful workstation that can take on even 11K Insta360 Titan footage.
Haha, Titan matches Titan, no punch intended.
I am not going to go into the detailed spec of my Maingear PC.
This will be another video b/c it's complicated.
But just know, my CPU of choice is the Intel i9-9980XE - an 18 cores CPU with turbo boost
to 4.40 GHz.
Why not AMD RYZEN Threadripper 2990WX with the 32-Core.
There are many reasons why I choose intel instead of AMD Threadripper.
But the most obvious one is Thunderbolt 3 support which I mentioned why in this video.
Basically, my bottleneck on 8K 3D 360 production will be in the storage most of the time - and
having a thunderbolt based RAID 0 drive like G-drive Shuttle XL or Laci 6-Big is essential.
Okay, let's take a look at my current Nvidia RTX 2080ti performance inside Adobe Premiere.
Here is an 8K stereoscopic top and bottom project I did shot with the Insta360 Pro 2.
It won't have a real-time playback no matter what GPU I used.
So I will highly recommend you stick to my Proxy workflow right here.
Premiere is kinda leveraging GPU acceleration - with CUDA for Nvidia Graphic Cards.
But Premiere is not 100% utilize GPU render.
So for regular 4k 2D video editing and rendering, you won't benefit too much from Titan RTX.
But for immersive video editing, all the effects or video filters you see here, are GPU accelerated.
To easily see that, you can turn off Hardware acceleration and immediately see this RED
warning bar.
So to truly benefit from your fancy GPU, you need to make sure your video filters are all
GPU accelerated.
All native immersive video filters, BorisFX Continuum VR units, Mocha Pro, Mettle Mantra,
Re:Vision Effects, and NeatVideo denoiser you see here, are all GPU accelerated.
Each decision you make on how to process your video footage will significantly impact your
time spent on playback and render.
And that is why so important to make smart choices.
Not all VR video need sharpening if that mean saving you hours of rendering time.
So my render of this 10-second 8K 3D video with all the immersive filters and ambisonic
audio take around 17 minutes to finish.
Looking at the resource monitor, both my CPU and my GPU are not maxed out.
But the dedicated GPU memory is hitting 7.5 - 8 GB.
This is just a 10-second test.
But for this video, which is 17 minutes long, way too long for VR, the GPU memory will entirely
be hitting the 11GB ceiling.
You also see all the GPU stat here with the Task Manager and GPU-Z for reference.
So now I switch to Titan RTX with the exact same PC from Maingear.
Before I hit render.
I open up NeatVideo Version 5 here and take a look at the performance.
When I use ONLY GPU render, I get average 1.03 frame per second, which is faster than
CPU with 0.8 frames per second.
I can relocate more GPU memory to this render to increase the speed, which I can't on the
RTX 2080ti 11GB memory.
The total render time of the exact same 10-second clip took about 13 minutes to finish - which
is 4 minutes increase speed.
It does not look significant, but think about it, it adds up.
The longer the clip and more GPU accelerated video filters, the more time you will save.
That is more time you can be productive instead of waiting around or screaming at your PC.
Take a look at the monitor here, the CPU is less taxing compared to the RTX 2080ti and
we use 21.5GB memory on this render - which is significantly higher.
You also notice GPU resource is around 70% compared to 2080ti, which is around 50%.
Is that mean Premiere is more optimize to Titan RTX?
We don't know.
We are using the Studio Driver from Nvidia - so maybe the Titan RTX is optimized.
Number is number.
It is faster, and that is all you need to know.
I quickly jump over to Mistika VR and do some render in ProRes 3D 8K - it averages around
3.8 frames per second - which is a pretty good speed compared to what I usually got
around 2.6 frames per second.
So in conclusion, don't expect a night and day performance increase from upgrading to
Titan RTX.
But if you can find clients or projects to justify the cost, it is a nice upgrade if
you have the CPU and PC to match that.
8K production is becoming more common in the immersive filmmaking world.
And new VR headsets are coming out that will greatly benefit from this.
I will continue to make more content on how to leverage the Nvidia Titan RTX - using software
like V-ray, RedShift with Cinema4D.
And how to build your workflow to increase productivity with all these new techniques.
The next tutorial will be focusing on Oculus Rift S and the Titan RTX - to find out how
they performed in demanding VR environment.
