Blackmagic Forum

Hey guys and gals,

I am new here, and have been using Davinci Resolve for about 6 months now. My desktop has an Intel Xeon E5-1620 v3 @ 3.50GHz, 32GB of DDR4 RAM, Nvidia K1200 graphics, SSD, running Windows 10. It does decent at editing 4k with proxies, and it struggles quite a bit with Fusion. What would be the best upgrade to this machine to help work with 4K editing? 1080 it does just fine and renders pretty fast.

My Laptop is a Lenovo Yoga 720 with 4K display, i7-7700HQ 2.8 GHz, 16GB DDR4 RAM, SSD, GTX1050 2GB. It struggles with 4K timeline and definitely with Fusion. Does decent with 1080 timeline and rendering, but still has some hiccups during rendering sometimes. When I try editing 4K, I get the "GPU Memory Full" warning constantly. What could I do this machine to get it to help edit 4K? It is nearly the same specifications as the Dell XPS 15's that seem to do fairly decent.

I'm tired of searching forums, google, etc. so I decided to ask here. Hopefully that is okay.

Thanks,
Josh

I'm fairly new to resolve, but I've noticed its quite taxing on hardware. Especially the fusion tab. I couldn't even open it on my old PC.
For your desktop, does it struggle with 4k even when using proxies/optimized media? I have found it essential to use optimized media in my workflow, even on my new machine, and it seems to work very smoothly. I would suggest opening task manager to see if you can see any obvious bottleneck when editing. I would suspect CPU or disk speed. Are you using the SSD for your footage?


Editing on a laptop in resolve is something I've not tried, but I imagine its pretty challenging.
In your case, I think the GPU is definitely the bottleneck. The only thing you could do about that is look into external GPUs.
But I'd suggest experimenting with proxies first. There are quite a few settings in fusion you can make to ease the load a bit.

Hi.

I will suggest you start by reading the DaVinci Resolve 15 configuration guide:

https://documents.blackmagicdesign.com/ ... _Guide.pdf

And here is a copy of what I wrote in this forum about the Dell XPS 15 the day before yesterday:

'Notebookcheck have done some test, they call it: 'Dell XPS 15 9570: 15 % more performance by undervolting'

https://www.notebookcheck.net/Dell-XPS- ... 738.0.html

It shows that the Dell-XPS-15-9570 is not set up for max performance, as it is possible to increase performance by 15% by undervolting the CPU. I will not recommend users of this forum to undervolt the Dell-XPS-15-9570's them self. But there are much better Laptops available. Normally do I recommend Laptops in a medium to large size, to get reed of the generated heat.'

It's a bit rule of thumb and depending one your 4k source material.

AVC and R3D are very hard on the CPU, Memory and not to hard on the SSD/HDD
ProRes, DNxHR and Cineform are all-intra and pretty light on CPU, medio on memory and harder on the SSD.
ARRI RAW and cDNG are medio core on CPU, memory and hard on the SSD.

Resolve 32 GB or more
Fusion 64 GB or more
GPU with atleast 1GByte/k(resolution), when you don't want to run out of memory all the time 2 GByte/k(resolution) and enough memory bandwith.

I'd recommend even more VRAM. HD can run quite acceptable in 2GB, while UHD/4K is 4 times the amount of pixels, so rather get 8 GB. I'm currently working on a huge project (4,5 hours) with the main camera in 4K and didn't have a single crash since DR15 went final in Edit or Color (Fusion is a different subject).

Agree, that's why I got ourselves the VEGA FE's with 16 GB of VRAM and never had a crash sofar with 4,6k cDNG and 8k.R3D Helium. And they also works on Mac's (over TB3) and have 10 bits color overlay in OpenGL.
