Are the NVIDIA RTX video cards good for video editing?

Written on October 1, 2018 by Matt Bach

The new RTX series from NVIDIA are not very exciting for Adobe applications, but they are great for DaVinci Resolve giving up to 20% higher performance than the GTX 1080 Ti. These cards are also very interesting cards for the future due to the addition of two major new features: Tensor cores and RT cores.

Are Tensor Cores used in video editing?

While already available on the more expensive Titan V GPU, the RTX line introduces tensor cores at a more reasonable price point. These tensor cores operate alongside the normal CUDA cores that traditionally do the heavy lifting, but are designed specifically for machine learning inference (running already created and trained machine learning models). Blackmagic has already announced that they will be using these cores in DaVinci Resolve 15 to "accelerate AI inferencing for graphics enhancement", but so far there has been no word from Adobe. Even if implemented fully, these cores will likely not improve things like live playback FPS or export times, but they will be used for things like shot color matching, denoiser, or automatic masking.

Are RT Cores used in video editing?

RT cores are brand new in this generation of graphics cards, and are specialized for a single type of operation: ray tracing. It is possible that these cores may be used in VFX or motion graphics, but if or when they will take advantage of is currently unknown.

These new features are primarily what you are paying for with the new RTX cards, so the primary reason to purchase them is to future proof your workstation so it will be able to take advantage of the tensor and RT cores in/when the future if the developers add support for them. It is currently unknown exactly how these cores will be utilized by Adobe or Blackmagic, or the kind of performance gains we may see once they are. However, we have already looked at how the RTX 2080 and 2080 Ti perform in a number of video editing applications as they are today:

Is the RTX 2080 8GB worth it for video editing?

In most video editing applications, you are unlikely to notice a difference between the RTX 2080 and a similarly priced 1000-series GTX card. In fact, you should get more VRAM from an older GTX card which makes the RTX 2080 slightly worse for 6K+ workflows. The main reason to invest in the RTX 2080 is to future proof your system in the hope that the new Tensor and RT cores will be leveraged in the future. Blackmagic has already announced that Resolve 15 will take advantage of tensor cores in the future, but Adobe has not yet announced their plans for these cores.

Is the RTX 2080 Ti 11GB worth it for video editing?

For Adobe applications, you are unlikely to notice a difference between the RTX 2080 and a similarly priced 1000-series GTX card. However, in DaVinci Resolve the RTX 2080 Ti performs on par with the much more expensive Titan V. For most users, however, the main reason to invest in the RTX 2080 is to future proof your system in the hope that the new Tensor and RT cores will be leveraged in the future. Blackmagic has already announced that Resolve 15 will take advantage of tensor cores in the future, but Adobe has not yet announced their plans for these cores.

Nice! I don't think this will affect video editing too much since even most 3D rendering apps use OpenCL or CUDA, but it is a pretty big deal for game development and other real-time visualization applications. If anyone comes across this comment and doesn't know what this is, this is a pretty good breakdown: https://blogs.msdn.microsof...

Could you please comment on lesser applications (for the masses) like Cyberlink Power Director (just to name one) and the advantage or otherwise of using even a GTX1080 let alone an RTX2080. Will such powerful GAMING cards help much in video software other than the Adobes and DaVincis that you always talk about? Hard to find this info on the web - thank you very much.

Our focus is on workstations for professionals (or hobbiests looking to break into the professional space), so we typically spend our time on the more popular applications used in those fields. For software like Power Director, we really can't say since we haven't benchmarked these cards in that software. Some might make great use of the GPU so the RTX cards will be great, but smaller editing software tends to lag behind a bit in terms of taking advantage of hardware so in most cases by bet is that these GPUs won't really give you that much.

What rig would be recommended for After Effects .PNG image sequences/comps at or around 110 Megapixels? Yes, you read that right.

It depends on how much Ram you want for RAM previews and how much RAM something like that needs in the first place since I'm really not sure. Highest per-core performance on the CPU is best (currently that would be the i7 8700k) but if you need more than 64GB of RAM then you might need to settle for something like the i7 7820x. GPU shouldn't matter much, just get a mid-range NVIDIA like a GTX 1060/1070.

Storage is something to consider as well. I'm not sure what the effective bitrate is with that kind of sequence, but I have a hard time believing that you won't simply be CPU bottleneck so I doubt using a NVMe drive over a normal SSD will make that much of a difference beyond disk cache write speed.

Keep in mind that the Intel 9th Gen CPUs have been announced and we will have benchmarks up on Oct 19th for AE and other software. Intel has also announced the new X-series CPUs, but I don't think a launch date has been publicly announced

Thanks a ton for the quick reply! I've been struggling to find a reasonable rig to manage this massive project even with 1/16th scaling. I parted out a $6,000 rig on Newegg and an $8,000 Puget Systems rig but don't have much confidence that After Effects will even see a massive gain in render times proportionate to a price like that compared to the rig we have.

Currently the best rig we tried is:

i7-3930k @ 4.3GHz (which in the benchmarks I've seen isn't leaps and bounds slower than an i9-7900x or i7-8700k in single thread performance).
16GB DDR3 @ 1866 (trying to get at least 64GB installed but I don't have high hopes for improving render times, After Effects encoder reports average of 5 frames per second)
Samsung Evo SSD Scratch
Samsung Evo SSD Read
RTX 2080Ti

After Effects takes 1 hour to render 10 seconds to our needed FlexRes Performance container.

Posted on 2018-10-13 06:23:13

If I had to guess, I think a 8700k would render about 40% faster than a 3930k in After Effects. That's a pretty good speedup really and might get even better with something like the new i9-9900k.

Something else you might consider looking into is network rendering. We haven't done too much with it quite yet, but it is on our to-do list. It wouldn't help with RAM Preview, but if you want to cut down on final render times, splitting it up across multiple machines is likely going to be the only way to make big improvements to your render times.

I use Davinci Resolve and will be building a new computer very soon. From various articles I've read I'm steering towards a 2080 8GB card over the older 1080Ti 11 GB as they are similarly priced in the UK (although 1080Ti seems to be harder to find in stock now) and I will only be working on 4k video or lower. What I'm confused about is if there are better variants of the 2080 8GB card for editing? A lot of the variants of 2080 8GB graphics cards seem to be marketed towards gaming and I don't really know how that relates to editing experience, for example some have higher boast performance, some 3 fans instead of 2, some with OC in the name etc. I'm confused.

Posted on 2018-12-03 12:41:13

Pretty much all GPUs these days (outside of the workstation Quadro/Radeon Pro) will have all those different types. The ones with bigger heatsink and more fans are just designed to run cooler and quieter, OC (should be the same as the ones with higher boost clocks) are set to run above NVIDIA's official specifications in order to get higher performance. Personally, if this is going into a system that is designed to get work done, I would shy away from the fancy cards and stick with something as close to stock as possible. So, dual fan, not OC if you can help it. In apps like Resolve, those features aren't going to make a big difference, but the cards tend to be less stable. To me, I would much rather have a GPU that is less likely to give me any problems than one that is theoretically a few percent faster.

Will you guys be updating this with the new Titan RTX? I am in the middle of trying to do a new Resolve build and thinking of going all in of future proofing by purchasing the Titan RTX. Also, slightly off topic... I find myself doing much more in the fusion tab and using OFX from Boris and my timeline is being bogged down. Do you know what I need to upgrade to have performance in that area? My current machine is pretty old but still gets the job done. i7-6900K, Titan X, 64 gigs of RAM. I was considering the 18 core i9 until I just looked at your review of it.

Posted on 2018-12-29 14:27:12

Yes, we will. We just got our hands on our first Titan RTX, and should start doing some testing here pretty soon. However, keep in mind that the Titan RTX only comes in the dual fan design which is not ideal for multi-GPU configurations. So if you ever think you will have more than one (or maybe two) cards, the Titan RTX will likely throttle to speeds lower than a 2080 Ti that has the proper rear exhaust type of cooling. You can see how big of a deal it can be in one of our posts: https://www.pugetsystems.co...

Fusion doesn't really use the GPU all that much compared to the rest of Resolve, so in most cases you are going to be limited by the single-core performance of your CPU. Check out https://www.pugetsystems.co... and https://www.pugetsystems.co... if you haven't already. If fusion if your primary worry, the i9 9900K is currently the best CPU you can get since it has terrific single core performance. The 18 core i9 9980XE is going to be somewhere around 20% slower than the 9900K.

The biggest issue with the 9900K is really the 64GB of RAM limitation. Especially in Fusion, having more RAM can make a big difference since Fusion stores already rendered frames in RAM. If you run out, it simply overwrites old frames which means the system has to completely re-render those frames from scratch if you play through it again. I would check out task manager to see how much RAM you end up using. If you are anywhere around 55GB or so used, you would probably see a pretty noticeable boost in performance with more RAM. It won't help the first time you play through a Fusion project, but it can really add up as you keep working.

hi i've been looking for some research now as i can only afford the rtx 2060, is it good enough for video editing, 3d modelling? for video editing i use AE an Sony vegas. for 3d modelling... let's just say i'm still about to learn it.

this is the specs i have:
Core i7-8700
Asus ROG Strix H370-F
16GB [2xGB] Team Nighthawk RAM
Crucial BX500 480GB SSD
1TB WD Caviar HD
Corsai 80+ 650w power supply
palit rtx 2060

For After Effects and 3D modeling a RTX 2060 should be just fine. Only thing to be aware of there is if you end up using any AutoDesk products (3DS Max or Maya primarily) since they officially only certify the Quadro/Radeon Pro line of GPUs. That said, we've never encountered issues with the GeForce cards in those software packages so it is more a case of it being something AutoDesk support could potentially blame as the culprit if you ever have a problem with their software.

Thank you for your reply. Is Blender program a good to go for rtx 2060?

Posted on 2019-02-13 18:27:07

Yep, Blender should work just fine with the RTX 2060!

What about avid media composer. Is it worth to invest extra money into for example RTX 2070 over GTX 1060 and save money on getting i7 8700 and not i9 9900K or should I get rather better processor for better results ?
