Want to post an iphone 4 video on youtube, but it needs to be rotated
Quicktime allows you some basic editing options such as Edit > Rotate
iMovie allows more options such as cropping, rotate, trim, etc.


When you view your video in Quicktime is it in landscape format? If not, it's possible the phone was vertical (portrait) when the recording started. The camera should oriented either landscape or portrait before pressing record.
