I seem to be spending a great deal of time waiting for things to render, and I don't know why.  For instance; I just copied a few clips from a project I was working on into another project and now all of the clips are re-rendering and it slows everything way down.  I have also noticed that in the render window the "Transcode and analysis" process is taking FOREVER!!  Why is this?  I'm shooting with a Canon 5D at 1920x1080 24p.  Might this have something to do with optimized versus proxy media?

MacPro (Tower), Mac OS X (10.6.5), Final Cut Studio

It sounds like you didn't optimize your media on import. Your camera shoots in a highly compressed aquisition format that should be converted to ProRes 422 for editing. So you invest the time when you first bring the media into your project, instead of rendering every time you make changes.


Larry Jordan explains it well here:

Ninety minutes is a lot of video. You're basically rebuilding the entire video timeline. Are you working with optimzied media or native H.264?


If you're going to be sending a compressed version, it might be better to make a master and use Compressor to encode, applying the timecode overlay there.
