Question

PC Build for 4K video

I searched the forum but didn't see a recent post for this question, so I thought I'd start one. I am getting ready to build new computers for our editing suite. With 4K video being here, I'm wonder on what elements I'll need to build a machine for Adobe Premiere Pro and After Effects that can handle multiple cameras of 4K video without lag and that renders quickly. We spend the majority of our editing time with computer related delays. I'd like to circumvent that Any advice?

    Hello!

    Immediately apologize for my bad English)))

    I bought a laptop Asus ROG G752VS to work in Adobe Premiere Pro. On the laptop Fixed: 6700 i7 HQ, the GTX 1070, 48 GB of memory, the SSD 256, 1000 SSD.

    When playing video DJI Phantom and 4 CAMERA Sony A6500 (xavc) processor hammered by 100% and start missing shots (CUDA activated support). I understand processor clogged decoding video files for playback. For example, in a monoblock Lenovo ThinkCentre without Nvidia graphics card, only with Intel HD Graphics 520 Tacca passes and no processor loaded on 30-70%.

    Can I somehow configure the hardware decoding of h.264 on 1070 GTX in Adobe Premiere?

    Thank you in advance!

    Hello Anton! You might want to look into this thread: NVidia GPU-accelerated H264-encoder plugin, ready for public testing -- there has been some development on a third-party plugin to use NVidia's NVENC to encode on the GPU. There are lots of folks in that thread that have bugs and other issues and it seems the plugin can break whenever there's a driver update or Premiere update, but it might be something you can try in the meantime. I haven't tested it myself. I'm holding out for Adobe to support NVENC directly in AMME.

    How's this seem (PC Part Picker link):

    Core i7-6950X 3.0GHz 10-Core, GeForce GTX Titan X 12GB, Level 10 GT Snow Edition ATX Full Tower - System Build - PCPartP…

    (not priced on list is $1600 additional for processor)

    It's a lot more expensive than I had heard should be sufficient... Is this overkill?

    FYI - I dont do any gaming. This is simply for video production (Premiere Pro and After Effects). I'm thinking of getting the Atomos Ninja Assassin 4K video recorder to add to my gear and I'll need a machine that will handle it without pissing me off.

    We do 1-3 camera shoots most of the time, plus animation clips, titling and what not.

    Here is a interesting data rate chart that I just found that should give you information on what you are going to need for storage speed read rate for your editing suite versus media type.

    On the Processor Frequency vs. Cores issue you mentioned earlier, I recommend this: https://www.pugetsystems.com/labs/articles/Adobe-Premiere-Pro-CC-2015-Multi-Core-Performance-Update1-806/ and https://www.pugetsystems.com/labs/articles/Adobe-After-Effects-CC-2015-3-Multi-Core-Performance-843/

    Essentially, the number of cores offers diminishing returns depending on what you're doing and in general it looks to be better to spend money on faster processors over raw number of cores if you end up in an either/or scenario. In fact, at 1080p, more than 2-4 cores does almost nothing for performance in Premiere and AE. At 4K it looks like you do get more boosts up to about 10 cores--as long as those cores are on one chip. It looks like neither app (at least according to their test sequences) benefit much, and are often harmed by having more than one chip in your system.

    Also don't just look at CUDA cores and processor speed on your video card. Make sure you also get the highest Memory Interface Width and Memory Bandwidth you can (both those specs should be listed somewhere in your card's specs). Those numbers vary by manufacturer, so be sure you're not shooting yourself in the foot by getting a video card with a lot of RAM but low on those other stats.

    I should note that this is all theoretical for me based off research. I don't have your proposed system or a variety of systems to double-check this information.

    Thanks!

    With the CPU is the speed (3.4GHZ vs 3GHZ) more important or less important than the number of cores (6, 8, or 10)?

    I'm going to try to build this in pcpartpicker.com to see what we're looking at.

    I have an 8-core i7 running at overclocked 4.5 GHz recently I had a submission of my Premiere Pro Benchmark (PPBM) by a proud owner of the new 10-core i7 and he was running his at overclocked 4.2 GHz.  My score on the Premiere based CPU intensive score with CC 2017 was 250 seconds, he beat my good score by scoring 205 seconds!  If you can afford it cores and clock speed count. 

    By the way his CPU intensive score with his overclock beat the score of a dual version 3 10-core (20 total cores) non-overclockable Xeons.

    By the way his custom computer with the conservative overclock was designed specifically for his workflow; it was built, tested, delivered and fully supported by ADK

    1. i7 Broadwell E CPU.....at least 6850K six core at $589 , up to $1578 for 10 core monster....on good X99 motherboard

    2.  NVidia 1080ti GPU.....expected out soon, will be near Titan X in performanc for less....around 8 to 9 hundred.

    3. 64 GB system memory.....at least 32...no less

    4. One Samsung 256 GB or 512 GB, 850 Pro SATA III SSD for " boot drive" with ONLY OS, programs, and windows page file on it.

    5. One Samsung 960 Pro NVMe PCI SSD as " project drive" to hold hold ALL files except what is on boot drive. This drive is available soon in 1 and 2 terabyte versions......unsurpassed in speed......over 3 GB/sec read, 2.5 GB / sec. write.

    6. Your choice of either SSDs, or, large "enterprise level" 7200 RPM HDDs for archiving and backing up.....NOT to be used during editing.

    7. Quality and plenty sufficient power supply

      make this one a sticky and then most posters on here can go on hiatus for 6 months until the "new" stuff comes.

      very concise.
