Crude interface and no actual files
Movie Clips Frees trim function is as crude as it gets, with no way to adjust precisely where you want the trim points. All you can do is draw a rectangle, with the left side being the left trim point and the same for the right. If you try to adjust the trim points from there, youll find that your trim points are gone and youre simply drawing another rectangle. There is no way to preview your trims, so you can only hope that anything is actually happening. There is also no help system at all. But all this is moot, because when I tried (hopefully) trimming some videos and exporting them, the saved files were zero bytes, and could not be opened when tried with four different video apps.
