I wrote this tutorial for the HRC blog:

“Did you ever record video that you wanted to rotate? Have you ever rotated a clip and you were left with extra space on the side you wanted to crop out? I recently worked on a project where we had to rotate video clips and crop out the extra space. The tool we used on the Mac was MPEG Streamclip (http://www.squared5.com/). It is a free video conversion software. Here’s how to rotate the clip and crop it in MPEG Streamclip.”
