When layering video in the timeline, for example, putting b-roll over a voice track, is there any way to view the change without having to re-render every time. I am used to being able to see my changes to decide if I like them but every time I make even the smallest change, like moving a clip over just a bit or extending a clip, FCP tells me I have to re-render. It's so tedious and time consuming. Is this just the way of FCP or is there a way to view my changes as I make them? Thank you for any help!
