Eternal background render

Hello. I've got a big project and opening it I always see background render on start. Sometimes it takes a lot of time. After a while it stops. Then on reopening some other render starts. I wonder why it doesn't save the previous render job and seems like start rendering again and again. Any suggestions? Thanks.

I would turn Background Render off in the preferences. I know others would concur here on that. I've had render files disappear if I render something, and then quit out of FCP X right away. Do you need to render? I render if I'm working on a title or build-out of some sort, using the Modify>Render Selection.

Interesting thread on rendering here:

Thanks. And when you render selection, does it save rendered material for the future when you close the app?

It SHOULD save changes. I can’t confirm this but maybe you have to make some edit/change to Project (timeline) and after a couple of minutes close FCP.

One thing I’ve observed, and this is a combination of large project with lots of titles, effects, etc, and my really old mid 2010 Mac Pro:

When I re-launch FC, it takes a minute or to for everything to “load”. The last things to load are the render files. So maybe launch FC, go get coffee, and all may be good.
