New PC for Edius
 
Hello there I have a tricky problem to solve.

Currently I cannot take advantage of Intel Quicksync to boost Edius as my main system is Xeon based.

I currently have a dual Xeon Motherboard with 5 PCIex16 slots which is a facility impossible to get in the i9 Motherboard types. Also I discover that the number of PCIe slots supported can depend on the CPU lanes when working with single CPU's.

I was hoping to transplant all the hardware from the current system to the new one.

I currently have the following PCIe hardware supported.

Slot1 Sonet Tango 3 USB3/Firewire card
Slot2 Gigabyte Aorus GTX1080TI watercooled
Slot3 Atto FC41ES Fibrechannel card
Slot4 Storm3G Elite
Slot5 Decklink 4K 12G Extreme

The nearest MB I can find to support an Intel 9980HK is an Asus WS Z390 which looks like it will give me the slots I need.

The i9X series whilst they have more cores drop the integrated graphics, which doesn't move anything forward.

Some advice would be appreciated.

Regards

Mike

Mike, is Quick sync to be used mostly for export purposes?

I like Asrock and the Taichi Ultimate will give you 1@16x, 2@8x8, and 3@8x4x4 split. Remember, the Z series boards
only have 16 pci-e lanes available. You also get 2 PCI-E 1x lanes through the chipset.
The chip you mentioned only has 16 lanes available.

I'll mention the Asus Z390 WS, but based on the items such as the Fiberchannel card or the 12G Extreme, I don't think the Plex chip
could handle that much of a data flow and keep up with what ever you are doing when both are fully active and the 4th 16x slot is occupied.

Using Edius you won't notice any difference running the 1080ti at 8x. Since the Decklink 4K 12G is an 8x lane card
the GPU and the Decklink eat your 16 lanes.

Maybe build a system which can be networked through your main system. That way you aren't eating up the resources.
You would get the access to the main system's Fibrechannel card through the Aquantia 10 gigabit built in network card in the Taichi Ultimate and
the 1080ti and Decklink will both work at 8x and be happy. If the Sonet is a 1x card, you would be covered for that.

Basically, there is no way to put all of your items into a Z series system.

Hi Mike.

To further Jerry's question. If it's not for decoding and only for export, just use a HQX temp intermediate file into an external encoder for h.264/h.265 that's NVENC compatible, Handbrake is a great option and its free.

Cheers,
Dave.

another free option is hybrid video converter

..and playout of H265/H264 material, I can get the H265 export covered by Edius>XAVC>TMPEG Mastertingworks7

There is one thing I have never understood, in that any file that Edius finds difficulty in playing back always plays fine on the desktop, so the PC itself is perfectly capable, but there again often the players have GPU hardware acceleration they can use, which Edius generally doesn't use.

For the Xeon PC that would of course be our best solution.

It is a lot of expense just to get QuickSync working, and as you can see it's not the easiest of hardware setups to get working.

I assume that you are talking about timeline editing and using QS for decode? We all must hope that EDIUS in the next release starts to use the other more powerful GPU's than just QS. That would allow a move to AMD CPU's that have a lot more lanes available than Intel parts. Also with the latest 7nm Ryzens PCI-e 4.0 for faster NVME memory use too.

If it is for export then I agree with Dave and use HQX to another encoder like Handbreak or WM7 ( my preference now)

Just as comparison I am still on E8.53 but performance with my Threadripper for UHD editing is not as good as using Resolve Studio. Neither use GPU for decode for timeline playback on my system. So I think there is room for improvement within EDIUS apart from using QS for decode to use available cpu resource. Resolve uses 1/3 the resources of EDIUS and playback is faster. Most of my EDIUS editing is multicam in a 1920x1080 project so just run at 1/2 preview resolution is fine. No different to my second 4790K system with QS really !!

Mike, you can't compare playback from within an NLE to a stand alone media player. They are two completely different animals.

Yes one just decodes for playback to whatever the screen is and the other converts to the NLE core format which could be 32bit RGB or YUV and then plays back to preview monitor. Much bigger task as it has two things to do at the same time especially if the source is LongGOP . I think this is where the differences may be between how different NLE's manage this task.

I am finding a few issues.

Primary color corrector is more efficient with GPU off than with it on.

NewBlueFx crashes Edius with GPU on in the NB GUI, but is fine with it off.

Playback will not stand many effects such as color correction or titling if the frame rate does not exactly match the project. 50i in 50p or 25p in 50p. Multicam is certainly no good with a variety as above of camera frame rates.

Sometimes HDV footage won't play well 50i in 50p.

Yes Ron agreed there are it appears playback efficiencies that need applying

Mike, the only thing you mentioned that I have issues with is that you can't put many effects on a 50-60p UHD clips and get smooth playback. This is mainly a CPU power issue.

Everything else works fine in my system.
