OK, this one is off-topic but I thought I’d share.
I’m sure you are far more clever than I, but last night I shot a video of my daughter with my phone.
When I finished I realized that I had shot the video in portrait rather than landscape, which meant when it was posted online you’d have to cock your head to one side to watch it:
To try and rotate the video I had visions of having to surf through forums, download some specialized software etc.
Thankfully it was far easier.
It turns out Windows Live Movie Maker (free download) fixes it with one click of the mouse.
For what it’s worth
