Well, let's see. The Panasonic E85comes about as close as any to clean edits. The E85 allows seemless playback, assuming proper options set. The "Gotcha" is that -r high-speed copies have that cursed freeze at each edit point.
The work-around for that is to dub to the -r in real time, or for multiple copies, real-time dub to -ram, then high-speed copy the -ram back to the hdd. Now you can high-speed dub to the -r's.
Or, edit on the pc, an art that after three years I have not yet learned.
