I recently shot some of my first video with the 7D. It was at a wedding where I turned the camera to portrait orientation to film the bride and groom's first dance. When I play this back, it is displayed in horizontal orientation. In-camera auto rotate does not affect video. So unless I want to turn the TV or monitor on its side to view the video in an upright position, it makes watching the video a bit of a hassle with turning one's head sideways.
I called Canon tech support who said I should only shoot video in landscape orientation and recommended using ZoomBrowser to rotate and burn the file as an avi file to a DVD. I tried this which partially worked. I was able to rotate the file and convert to file to avi and the avi file played on my computer but the sound was lost in the transition. When burned to a DVD, it would not play on my DVD player (likely the DVD player's fault). I would like to send the video (with audio) to others to view. Does anyone have any suggestions on a better fix? Thanks.
