(Montage Creators) How do you guys easily get videos out no worry and have almost no problems ever?

(I edit fortnite montages) I have had so many instances where I've spent weeks trying to solve export problems and some I have never solved. I want to know if there are any tips you creators have when you guys use might use atleast 10 effects on a single 3 second clip, and you don't even think twice about something bad going wrong. 

Is exporting the montage into different parts a method?

Am I supposed to just remove effects if I add too many?

It's really a hastle to spend all my time working on making the montage and then spend half of the time just trying to export it in the lowest quality to atleast see it in a video file.
