Trying to make a video using some clips we have stored on the computer. When i import one file, say 3 mins long, its gets split into 4 seperate files. One 15 seconds, one 21 seconds, one 32 seconds and one 1min 52 seconds. Is there any way or regulating so all clips are even length? Or is there any way of further breaking down the 1min 52 clip???

First time trying to use it and havent a clue. Any help appreciated.
