FCP runs just fine with 8GB RAM. The important stuff like 4K playback in timeline, curves/grading/LUTS are all super smooth with no dropped frames.Sorry. Forgot the most critical info… I’m new to video editing, but a quick learner, but obviously don’t earn money with it. That said, I have enough of it, so no need to count pennies, but also don’t want to waste cash on super useless stuff.
Will do it only for private purposes/fun. Cycling Footage.
Intend to use Final Cut Pro.
Export time (the least important bit) is the only place you will see any noticeable difference. I never wait for an export and usually grab a coffee, answer email etc so the difference between a 5 minute render compared to 8 minutes has never been a concern.
Only time you’ll need more RAM is if you start adding lots of effect plugins, motion trackers, text layers. This is were 16GB would be beneficial and save having to convert clips to ProRes when the going gets touch if you end up using some crazy difficult 10bit camera codec.
