Sequence Problems

We got our teacher find our 2 minute marker. So we was able to know how much more footage we needed.  We saw we still had about 40 seconds left to film so we went away and got lots of different videos. However we have recently discovered that the marker was actually put onto five minutes instead of two minutes, so we actually already had the right amount of footage. This meant we has to get rid of lots of videos and shorten our soundtrack, so it could fit.
