this is my first time using this website so I'm sorry if i make a mistake or anything.
my issue is when i use compound clips, i get to about my 7th or 8th one and the program starts moving slower. when i get to my 10th compound clip, i get the rainbow wheel and it keeps on loading. I'm not sure what it is and to fix it i usually force quit and try to export everything I've done and then make a new library with the exported video and finish my project in another library.
I'm using a MacBook air early 2015 (it's updated and everything) so i think that might be an issue but i was also just wondering if anybody else has this issue and if they have fixed it differently?
