videocards they're good for you know anything to do with video right I mean it spits write a name video card they've got features to enhance video playback in real time they've got dedicated hardware to accelerate video games and they're a necessary component of any system that needs to output video to a display at all but what about video editing this capability has been featured prominently on the boxes on video cards for over a decade but do they actually make any bloody difference or should you just get a beefy CPU and tackle your video rendering that way let's find out shall we the mastercase 5 by Coolermaster gives you the freedom to truly make your mid-tower pc case your own with a variety of modular parts and accessories check out the link in the video description to learn more let's start with a little bit of background on why it is that we are doing this we make videos and one of the most tedious and time-consuming processes that slows us down aside from our servers being broken is transcoding footage for faster performance in Adobe Premiere a process that you can learn more about here and encoding our finished videos using the optimal resolutions and video codecs for the various platforms that we publish on including YouTube vessel and Billy Billy comm so we discovered when we were developing our Sena forum workflow that GPU usage in our workstations was much higher than we expected with certain workloads which is funny because we originally thought the gtx titan class cards and our editing workstations were basically because we can thing but something we never really had the time to investigate was which video cards are best for this process we just stuck with what nvidia had provided us back when we did our whole room water cooling project well now we've got an opportunity to answer that question for the Adobe editors out there for an unrelated project Super Micro just sent us one of their super server sys 4028 gr T RT servers this freakin badass of a machine is going to be used in a project where we run eight gaming rigs off of a single box with gtx 980ti amp cards from ZOTAC more to come but in the meantime it presented an opportunity for me and Edie to quickly and with relative ease without any physical access to the machine use on raid as a virtualization host and then use this thing as a remote test bench so Edie could shut down a Windows virtual machine virtually swap the video card to any one of the ones in here turn it back on and be ready to rock with a new set of benchmarks this led us exam how a wide cross-section of different video cards on both the AMD and NVIDIA side of the fence behaved in our typical video encoding tasks so the virtual machines were set up with eight core hyper threaded virtual processors to represent a high-end consumer or mid-range xeon processor and 32 gigs of ram the tests were done using the 200 gig boot SSD as a source and as a target and we used actual linus media group video projects for all the scenarios let's start by looking at the time it takes to export a time line containing mostly sinha form video clips in cinah form this is how we would normally send the project to the final export server for processing into h.264 and the only real conclusion that we can draw from this is that whether you go with AMD and therefore open CL acceleration or nvidia and therefore CUDA acceleration for your video workstation you're going to be getting a very similar experience just make sure that you do have a video card as relying on the CPU to do this work on its own is clearly a bad idea for the next scenario we're looking at something that would be more applicable to most prosumer and professional video editors so we're taking the 1080 piece in a form export from the first test and transcoding it to 4k h.264 no separate encoding server involved our GPU usage hovered around 30 percent and the advantage that our video cards enjoyed over the CPU only workflow diminished significantly here which might lead one to the conclusion that which graphics card you choose doesn't matter or even that a graphics card is really optional if you're exporting videos directly from your editing workstation except that our third test using chroma keyed Sena form 4k footage and exporting to 1080p Sinha form showed us what we were finally looking for the scenario in which a powerful video card demonstrates not just better performance against pure CPU encoding but also video cards so the beefiest gaming GPU in this case the gtx 980ti in the system comes out on top with the lesser cards performing about as much worse as you would expect given their overall horsepower and this would be applicable not just to pro McKee green screen footage but also to any project with other effects like limit recolor or warp stabiliser which leads us then to a really interesting final conclusion here AMD versus nvidia in this case doesn't seem to matter much the 970 and the r9 290 which is about equivalent to its 300 series replacement are similar enough across the board that I couldn't recommend one brand over the other for editing an adobe premiere with that said that might not be the case if you use other tools but the takeaway here then is that for video editing an Adobe Premiere you should get a GPU even if it's just a mainstream model and that much like for gaming once you get into the performance and enthusiast product range you are getting diminishing returns for the money you spend neat speaking of which this is pretty cool this is
