Slow, sluggish interface

It appears to be “maybe" working so far, first conversion is in progress, but it was maddeningly annoying just to get to this point as the interface did not seem to want to respond very quickly. My first attempt is to try joining two halves of a move. The system has been telling me a conversion time of 1 hour and 51 minutes for about 10 minutes now and my activity monitor is showing that the program isn’t really doing anything so I’m a little skeptical of how useful this app is going to be.

Update:
First attempt, joining 2 movie halves, resulted in a 21MB file rather than the expected 2.5 GB file. Follow on attempts at joinging result in a total tailure with no reason given as to WHY they failed. Lowering my 3 stars to 2. I appear to have wasted good money on this
