How can I turn around the image of a video?

I took a video of waterfalling sideways.Portrait image...Can I turn it to landscape?

• I was not aware that images cannot be linked and turned like you can turn images...and my wonderful waterfall is falling sideways. Is there anyway of turning it back to landscape as I am never returning to that waterfall....and am so annoyed. I tried to fit the full fall in...and had to go portrait to do that...and I just didn't think..

  Wow, What a great solution. I tried, I failed, so I'll never try again. That's not the way to do things. A mistake is a mistake, plain and simple. There is a way to rotate videos, you just need the apropriate video editing software. Programs such as Adobe Premiere Pro will allow you to do it. Search google for video editors or use the following link: http://tucows.com/Windows/AudioVideo/Video/VideoEditors/ Now, sometimes you use the word image instead of video which means it could possibly be a photograph that's tilted and not a video. To rotate a photograph, just open up any image editor, open the photo, and choose the option to rotate the image counter clockwise by 90 degrees. It's not that bad and it's not worth beating yourself up over.
