I´ve shot some video clips with a point and shoot camera and just need to rotate them from horizontal to vertical, no other editing required. I tried to do this with Windows Movie Maker but just can´t seem to figure out how to use it and have sent at least one clip into a parallel universe. Is there another program I can use to perform this task?

These are free and work well. You will find one in there to rotate your videos. Its pretty straight forward.

Thank you. The rotation program is in the link you provided and is very easy to use as you said.

One more tip: Copy the clips and practice on the copies to stay within your own universe.
