Hi there. I need some help or advice for a faster Mac. I have had all the Mac Pro versions from 1.1 to 5.1 then got a 5K i5 iMac. I am actually very happy with it. I have now hit an issue. FFMPEG encoding is to slow. I need to encode 150 1080P videos per hour and convert 8000 high res photos to low res photos. I use this program, Jalbum, http://jalbum.net/en/ to make web galleries. it uses FFMPEG for video conversion. For a sample set of 4 videos, and 280 photos, my 2014 3.5 GHZ i5 iMac takes 2 minutes 30 seconds. A 2015 4GHZ takes 2 min, 5 seconds. I tried various PC, and a tricked out Win 10 box with a 6700K - i7 and 1080 GTX video card took 2 min 3 seconds. Any suggestions how to get this to around 1 minute 30 seconds and still use MAC OS?
