Bro Waycool,
yes, it can be done, but there are certain limitations.
Using Final Cut Pro or Express, you can change the output resolution to a portrait size....
ie. instead of 720x576 for standard definition TV, you can change the output aspect to 576x720 and make it portrait.
However, you'll be limited to using file-based output because once you go thru a video-based output, the usual hardware like DVD players or TV input will only accept the standard TV aspect ratio.
Drop me a call if you need further clarification. :thumbsup:
