oh yeah, sorry i didn’t word

oh yeah, sorry i didn't word my question very well.
i know that part of it, i believe.
but, isn't the position of the shot done while shooting?
and, maybe this rephrasing would help.
let's say i've already cut all my footage, put it in order and sequenced, synced the music and sound effects and possible text and captions needed.
what else can be done?
