On an iPhone 4.
I am rather annoyed that it looks OK on my phone and upside-down on my computer. Is there any easy way to fix this? All software that could do this on a PC doesn't like .mov files
This just happened to me today. I accidentally started to shoot the video on my iPhone 4 in portrait mode before rotating the phone to landscape.
You can fix the orientation in
Quicktime Pro for Windows or Mac.
1. Copy the video to your computer.
2. Open video in Quicktime Pro (has to be Pro).
3. From the menu in QT Pro select Window-->Show Movie Properties
4. When the Movie Properties windows appears, select the video track, then click the Visual Settings tab.
5. On the Visual Settings tab there are button to change the videos orientation. So if you shot the video in portrait for example, select the "rotate counter-clockwise" button.
6. Exit Quicktime Pro and you should be prompted to save your file.
That's it!
