Thanks for the answer. I guess there’s nothing I could do about it then.
I also embedded this other question: What is really happening in the render preview?
Placing the playhead on a “render needed” position of the timeline, makes the computer
count for a while – rendering, I guess – and all looks nice. Is FCP doing these preview renders
in some higher format? And if so – why? It really fools the user. Does it have to do with time-saving?
