.. thought I'd add that it didnt take 4 hours to do the first 2 clips.

I can't remember what it said it was doing initially, but it did move on and do some audio, then onto the clips .... so I presume it must have done some re-encoding of the whole folder first hence the 4 hours.

Either way it was taking a long time ......

I'm using a P4 CPU 2.93Ghz with 1Gb or RAM.
