This software has just about caused me to burst a blood-vessel through sheer frustration. It continually freezes for minutes on end, triggered by such hugely demanding actions as dragging and dropping a short MP3 clip into timeline and, er, saving my project. Sometimes it doesn't come out of the freeze and I have to kill the process. Last time I did this, the autosave failed to operate and I lost half an hour's worth of work. The video preview is also marred by an infrequent black flicker which occurs if I set it to anything above Draft mode.
By all accounts, this software is meant to be great and I haven't heard tell of many other users having problems with it. My computer is in good working order (as far as I can tell!) and I'm not experiencing problems with any other software. My spec is adequate for HD video editing (take a look).
So, what's going on here?! This is driving me up the wall, plus I have a wedding film to edit in the near future, so I need to get to the bottom of it.
