I just upgraded from 17 to 18 mainly because I saw the new Denoise plug-in. I was debating buying Neat but decided to upgrade instead - big mistake! This new Vegas Denoise is really way too slow to be of any use in normal video editing!
Machine is an i7-8700K (6 core), 32GB, all fast NVMe SSDs, Built-in Intel UHD 630 + Radeon RX 580 - both enabled.
I've tried a few different usages with the same result, he's a sample. 14 sec 4K XAVC clip from a Sony NX-80. Dropped on a 1080 timeline. Clip takes about 14 seconds to render using MainConcept (software only) to a 1080/8Mbps mp4 file. Add the denoise plug-in to the clip (lum- 1.5, chrom - 3.0, sharp - 0). The same render that took 14 secs before now takes almost 10 minutes - for a 10 sec clip! The only difference is the Denoise Video FX added to the clip!!!
He's the interesting part. During the render if I pull up task manager I see usages of - CPU: 2%, Memory: 10%, Disks: 0-1%, Intel GPU: 0-1%, RX 580: 0-1%. So, it's not using any resources - what is it doing????
If I try a GPU accelerated render (either Intel or AMD) it gets slightly faster 7-8 minutes but again the usage is almost nothing with the usage for the GPU selected maybe increasing 1%.
Am I missing something? Is there a secret switch somewhere to make this work? Why isn't it using resources and rendering faster?
