DaVinci Resolve performance issues

[Energycore]

Hey y'all

 

So friend of mine has been trying to edit video using DaVinci Resolve, but his performance has been quite lackluster. Here are his specs

 

CPU: Ryzen 2700X

RAM: 48GB DDR4 @2133MHz (I'll be enabling XMP etc for him tomorrow)

Storage: 2x Crucial P1

GPU: RX 570

 

Apparently, there's no problem using the software in general, but when he tries to apply a Magic Mask the preview fps tanks down to like 3, even at 720p.

He already tried pre-rendering the magic mask effect before previewing it. Did not help.

 

I don't have a screenshot but he claims that CPU and GPU usage during preview are very low (5% ish), so I'm thinking there might be a software issue.

 

Any ideas as to why performance is this bad would be much appreciated!

AFAIK magic mask is only in the version 17 beta, it’s not a stable release. It’s also working from the neural engine so performance is going to be clunky. 
 

Only thing you can do is make sure their GPU acceleration is set up properly. Otherwise I’d just wait until 17 officially releases and go from there.

Thanks! We spent some 8 hours today and managed to make the performance better with some optimization, but like you said Magic Mask was still really hard to run.

 

In the end we settled with "use the pre-rendered cached timeline to preview the effects, it's going to be tedious and time consuming but it'll work. Otherwise try not to use it and instead use more traditional, but worse looking masking effects".

 

If you know by chance whether Adobe Premiere has this kind of machine learning masking algorithm, I'd love to know and I'll tell him to use that for that step.

Not in Premiere, but in After Effects there’s the rotoscope brush (2) which achieves the same ends... mostly. It’s still slow though.
