[X4U] How do I rightside up my upside down video?

[Crandon David]

Hello All,

I took an HD video with my Samsung Galaxy S phone (T-Mobile Vibrant).

Given that the phone has an orientation sensor, I didn't realize I  
actually took the video upside down.

So, when I transferred it to iPhoto, it plays upside down. The rotate  
function of iPhoto doesn't affect it.

Is there a rotate function elsewhere? Such as in iMovie?

Thanks for the help in advance,

David
