Some videos need to be cutting on 2 parts for old fat32 flash
So menu call for cut video by 2 parts in the middle: first part 0-50% and second part from 50%-100% (some seconds back) and save this videos as: filename.avi > filename p1.avi + filename p2.avi
And in 3 parts for bigger videos, and in 4 parts for even bigger videos :)
You need the software called mkvtoolnix which will cut your input file after a desired size.
