Workstation Graphic Card for 4K Video Editing/Recording/Live Streaming

waynekrszwda · Feb 12, 2018

Hi..I'm confused over all the choices available for graphic cards either gaming or workstation for 4K video editing and 4K Camera live streaming - I'm a semi pro videographer and an experienced live streamer - I'm not a gamer. My current PC build is as follows: MOBO- MSI Z370 A Pro., CPU - i78700., 32 GB Ram ( 2666 Mhz)., Samsung 960 EVO M.2 250 GB ( Windows 10 Home )., 1TB SATA HDD., Thermaltake Smart Series 750 watt power supply., Blackmagic Design Decklink Mini Recorder 4K (SID and HDMI Inputs)., Inogeni 4K to USB 3.0 Capture Card. I had the MSI GTX GeForce 1080Ti and was experience problems i.e., the video capture (using OBS., VMix and Wirecast) was experiencing bottlenecking ( staggering-stuttering video) even at 1080p I upped the Ram to 32GB yet still had the problems. I was told by a technician that the GTX series card was not designed for or compatible with 4K video editing or live streaming - is this true? I was then told to go with a workstation card like the AMD FirePro w7100 or higher or the Quadro P4000. I sent the 1080Ti back for a refund and will now take a loss at NewEgg.ca because of the 15% restocking fee etc. As well I don't really know if the MSI Z370 A Pro is the correct motherboard or not for my plans. Can anyone help me? Desperate!

I can see why you have bottlenecks in 4k editing. U need a really powerful computer for that.

But 4k streaming shouldn't be a problem as long as you have a fast internet connection. Did you check if it was a network bottleneck?

You can also check if you are having a cpu/gpu/ram bottleneck during ur editing sessions by monitoring the usage in task manager.

Hardware wise, it would be better if you can get a 8700k so that you can have an all core overclock to 4.7-4.8ghz?

The 1080ti is actually a good video editing card for softwares like Vegas pro/priemer pro or after effects. It just helps you with the Cuda acceleration.

But the titan xp is kinda like certified cuz it got the same Quadro drivers for workstation tasks.

Also a USB 3.0 for 4k data transfer will be awfully slow. You need thunderbolt or pcie cards for that.

thanks for your reply...I don't have a network bottleneck..I can record my production offline with the encoders i.e., OBS., VMix, or Wirecast. I believe the GTX series cards are the issue here...the first was the 1060 6gb then the 1080ti...both could not stream live from my cams in 1080p with the two capture cards. I can understand and accept 1 cam having issues with one capture card but all 3 cams having issues with 2 capture cards? The i7 8700 is a pretty good processor and with 32GB Ram at 2666Mhz, live streaming and recording with my cams in 1080p (uncompressed h.264 codec) should have been a breeze. So there were 2 things in common: the GTX series cards and the MSI Z370 A Pro Motherboard - I don't believe the board is the issue. I'm going with a workstation graphics card - either the AMD WX 7100 or the Quadro P 4000. The cards worked fine when playing a rendered out MOV file ( and other formats like AVCHD.M4 and MPeg4LPCM) in 3840x2160 and even C4K. But when transcoding/encoding in real time the h.264 codec, bottlenecking occurred. The Titan XP is waaaaay out of my budget at this time lol. Thanks for the reply I really appreciate it.

So, Finally (Oct 2018) with which GPU Configuration you went ahead? And how was the performance in 4K editing and realtime preview with Premiere Pro and After effect?
