Okay I'm new to video editing so I need some help. Some friends of mine shot some videos of me and my other Friend boxing the other night. and I'm trying to edit them into one video. I downloaded avs video editor(because its free) but it puts the videos upside down when i try to edit them...well actually some are sideways. how can i fix this problem? I'm trying to edit it quickly because its pretty funny. here's a link to the videos.
YouTube - questsplits's Channel
back story is old high school jock learning "this ain't high school no more"

i got the raw quick time videos, if some could put all the videos in order quickly or explain to me how to do it it would be greatly appreciated.
