HOWTO: Rotate your video in QuickTime Pro

nice tutorial
i like the gallery idea

It's a nice way to rotate videos; however, I must point out that if the video is multiplexed with the audio (such is the case with the videos recorded using former models of HP Photosmart cameras), exporting the final, rotated video will send out only the video stream, omitting the sound entirely, no matter the export format. A way to deal with this is to use MPEG Streamclip to demux the files, then rotate and export the video, and finally merge the two distinct files into one again using QT Pro.

If anybody else has a better idea, please say so:)

If you don't uncheck "Preserve aspect ratio" in step 4 (Visual Settings) the image will be stretched. At least is was for me. I unchecked the box and it was fine.

Thank you, I just made this mistake last week. :-)
