As Eric mentioned there are two different possible background processes =
going on that you can turn on or off and control in various ways =
including codec type of course.

1.  You can choose whether to transcode in the background any native =
source video to an intermediate like Prores on ingest of source footage =
(or later at any time during the edit; FCPX also unwraps source footage =
automatically if necessary). Whether you are transcoding source or not, =
you can immediately begin to playback and/or edit with the footage. When =
the footage is done transcoding FCPX seamlessly starts to use the =
optimized transcodes rather than the native footage. You can delete the =
intermediate footage at any time and go back to using the original =
native source.

2. You can turn on or off background rendering in the timeline (or in =
compound clips) of effects, composites, and other clip modifications. =
But if you turn off background rendering you can still playback the =
timeline without rendering. Even on my old MacPro I can edit most =
everyday type of projects without rendering (couple of composited clips =
with or without alpha, titles, graphics, effects and color correction on =
each clip, audio effects). I did try compositing 20 1080p clips together =
which was easy to do when the playhead was parked, but my old mac choked =
on playback, so there are limits depending upon your CPU/GPU combo. I'll =
be curious to upgrade my CPU and test this again.

If that means a background encode/render to a ProRes or other proxy is =

thrown at it so far (on my 4.5 year old first generation dualcore MacPro =

variants of any SD/HD resolution or frame rate (and all legacy formats =
of course). Only exception I can think of is XDCAM at this point. I =

imagine this will be especially true for newer Macs.
