I downloaded this slideshow Circle Slideshow by chirang85 on Envato Elements but I can’t use it because my Premiere pro keeps freezing, and I have an excellent machine, Macbook Pro i7 16Gb 15". In this case, this happens when I download a mogrt template file and I’m going to customize it
Your machine is not so excellent for what Adobe Premiere needs. What version of Premiere Pro are you using? If you use the latest one or previews one16GB ram is minimum.
I am using Premiere for Mac version 15.4.1 (Build 6)
You need at least 32GB to edit heavy files. Or maybe the file has an issue. Contact the author directly.
