    Yikes. Okay, my drive was full. I had a million render files and HUGE files in the high quality media folder. I checked around and the word was that I could trash that stuff and transcode it again when I needed to, but, now it looks crappy, and when I try to transcode it, it’s dimmed. Will it rerender by itself, or???? I need to show this stuff to someone next week and I want it to look good. Ben, dammit, I’m using the magnetic thing successfully! P.S. Suddenly my drive has five terabytes!

    First, turn off background rendering, and never turn it back on.

    Second, select the Library in the Browser, from the File menu “Delete All Generated Media” and from there delete all render files. (Or just purchase Final Cut Library Manager.)

    Never trash anything inside the Library bundle manually (again, get Final Cut Library Manager), very bad idea, unless you really know what you’re doing.

    Do you still have the original media? Where is it? When you go to the Viewer menu, are you set to use optimized/original or proxy media? Make sure you set to use optimized/original media.

    What do you mean by “transcode it”? Do you mean export it to a file? Not sure what you mean there, or what is dimmed.

    BEN, everything is okay. I re-rendered all the clips I’m ACTUALLY USING so I could see the project as well as possible, since the quality is so bad to begin with. I will never never trash anything manually again. Promise. I will get Final Cut Library Manager. I’ve been fooling with those files manually and I’ll stop now. Thanks. There’s a function in FCP to transcode your tracks to 422 OR to proxy, but optimized is dimmed. see attached images

    Optimize only pops if your footage isn’t natively optimized. In other words, more difficult to edit footage such as h.264 typically will provide the optimize check box. But if the codec of the footage is already edit-friendly enough, then the box stays greyed out and you’re otherwise good-to-go, at least from FCP’s editing needs.

    Don’t bother with optimized or proxy unless you MUST do it to have enough decent playback to edit with, simple as that. I’ve never had to optimize or proxy anything in all my years editing. And turn off Background Rendering, that will create render files constantly that will bloat the heck out of your Library. It’s a flawed system, that Background Rendering.
