No, redoing the FX is the easy part. No edited episode exists on film. The completed episodes only exist on videotape. The raw footage is all there on film, sure, as far as we know, but we're talking about takes that were used, alternate takes that weren't used, etc. Seven years worth of episodes have to be edited together again almost from scratch. It took them seven years to do this the first time. Timecode may make it easier, but it's still going to be a far more daunting challenge than it was with the original Star Trek.I may be entirely wrong, but I'm sure I read somewhere that TNG was shot on film and then transfered onto video for editing/vis-effects. So the problem with making a hi-def release is all down to the effort in re-doing the effects, which are obviously more complex than TOS-R.
