Why does FCP X re-render projects that have already been rendered?
I've seen several posts about this problem, but have not seen a solution/explanation yet. I have a project in Final Cut Pro X that I've finished editing. I have background rendering on and I wait until the entire project is fully rendered. I then shut down FCP. When I restart, it reloads the project and then begins re-rendering it. The whole thing. This happens every time and the process takes quite a while (even though it's a short video.) I've trashed my preference file, but still it does the same thing. I can't even begin to tell you how much grief this has caused me. So much so that I just used the word grief for one of the very few times in my life. Honestly, I just bought this MacBook Pro (after years of struggling with Windows) in hopes that this would be better than a PC. That doesn't seem to be the case.
Thanks for any help you can give me.
