Arri Log conversions – Resolve render speed
I’m using Resolve Lite to do some conversions from ProRes4444 LogC files out of an Alexa to Rec 709 for editing. While doing the renders on a MacPro 2.4 GHz 8-core Westmere 8 GB RAM with the Radeon HD 5770 (1GB) card inside, I noticed that it went up to about 12 fps render speed.
Just to find out how slow a 2011 MacBook Pro 2.2 GHz i7 with 8 GB RAM and the Radeon 6750 (1GB) would be, I rendered the same clips off that. And to my surprise that came out at 10-12 fps.
In both cases the hard disks were external Firewire, (ungraded clips in one, renders in another) but at ProRes4444 data rate of 37 MB/sec I don’t think disk speed would have an effect on rendering.
So, if anyone is doing this workflow on more capable systems I’d like to know…
Does the full version of Resolve render any faster than Resolve Lite?
Will an nVidia card speed up rendering?
Will more RAM speed up rendering?
Would an eSATA or RAID drive speed up this type of file renders?I have just one node with very basic primary grades, no masks, no keys, no blurs.
I now plan to test this render on a 2011 iMac i5.

seem that you have No NVidia CUDA card …that would be the slow performance …
resolve Need 2GPU (and one have to be NVIDIA CUDA) to perform well in speed …

I think it could be the cpu. On my mac pro its definitly the cpu. Because it has realtime playback but not render…
