Its 4.21 and says Beta in the corner. Downloaded the other day. Ive put 2 in quite a few times earlier in the movie (as well as other lengths - 4 -5 etc no problems) but after about 20mins length, its decreasing in size max length is now about 0,005. Bear in mind Ive only just started using the software no its more than likely Ive upset something somewhere but just cant see what!
