I made some vids of Adam on my camera, but had to do it in a "portrait" type of hold (dang 6'3" guy dancing around in front of me waving his hands!). So now... all the vids are sideways!
I remember back in the day, someone told me how to get them rotated 90 degrees, some kind of program. They are QuickTime Movies, btw, from my Panasonic Lumix DMC-TZ3 - an oldie, but a goody!
