Did you take a video on your Iphone and when you viewed the .mov file it is flipped 90 degrees.\u00a0 This happens often and there is many ways to fix it.\u00a0 Just viewing with quicktime or VLC could work but VLC the aspect was way off.\u00a0 So I had myself swinging a golf club and looking like I am 3 feet tall.\u00a0 Windows Movie Maker can flip the video 90 degrees but then I have to export in different format.\u00a0 Not too mention I had 20 videos and it is very cumbersome to do.<\/p>\n
