Would it be simplest to convert the video to a compressed format that FCP can handle comfortably, upload to a secure server and the editor download to MBP.
If it’s just for the web, yes, it can be downconverted to DV on capture.
Then as the edit progresses, can the project file be emailed to the main editor for checking etc, since if they have the identical originals, it’s a matter of reconnecting media.
I would work on-line if you use DV. Put it in a ProRes timeline to preserve the quality of graphics.
Or maybe, if the final product goes to web, is there a suitable codec that can be edited down and uploaded ready for the web site?
H264 or SWF, for the latter you’d need one of the conversion apps like Video2Web or Flash.
Have a wonderful day.
