What video editing configuration do you have: laptop, desktop, Mac, Windows, RAM, CPU, Graphics card, etc. ?
Desktop PC with i7-6700 CPU & GeForce 1060 6GB GPU, working mainly with After Effects :)
I do some video editing using a BlackMagic Intensity Pro 4k, DaVinci Resolve, and Adobe Premiere. I'm on the Red Team! :-) AMD FX-8370, RX460 4GB. Smooth as butter.
