I'm not an FCP user, but from what I've seen on
the Intarwebz, FCP is crap at handling image
sequences. You'll get much better performance if
you use Quicktime Pro to convert your sequence to
a Quicktime movie, and then import that Quicktime movie into FCP.
In QT Pro, choose "File > Open Image Sequence".
Select the first frame of the sequence and choose
your output frame rate. After the sequence is
loaded into QT Pro, choose "File > Export".
Within the export dialog, you should drill into
the output settings and choose an appropriate
compressor. The default is H.264, which is
suitable for final distribution, but not for
editing. I recommend the Animation codec at 100%
quality, that's a lossless RGB codec which will
preserve your JPEG image quality and color space.
Of course, you can use many other programs to do
this conversion, such as After Effects.
BTW, Premiere does not have performance issues
with image sequences, it behaves as all
right-thinking programs do, and treats the
sequence as a single clip. I'm surprised that FCP
is so backward in this regard.
