We need to use a NLE because we create projects that not only include musically timed photos that require a lot of detailed editing (the FCP7 transitions helped cut down the time to make all those edits), but greenscreen, motion tracking, animation, etc. I’m holding onto FCP7 for now and hoping I can find a way to use Premiere or maybe even FCPX (but the last time I tried it, their transitions were a mess too. At least Premiere links well with After Effects).
