Premier Encoding

Hi. 

 I have a Project which is Chromakey but with my system is very slow it takes about 2 hours 

but with another system, it takes only 30 minutes. here is my workflow :

I sync and Cuts and do other things then for key I replace the video with after effects composition 

also in after effects, there are some loop animation and denoising,  key the video with keylight and back to premier for render that I render in Media Encoder.

With this way, the project in my system takes 2 hours long but in another system only 30 minutes

I Should mention that my system does not use GPU but the other sysem use GPU

MY SYSTEM CONFIGURATION : 

I7 9900K , 64GB , Nvidia 1660 GTX , 250 GB Samsung M2 SSD

 SECOND SYSTEM  : 

I5 - 10600K 32GB RTX 2060 250 GB Samsung M2 SSD
