When i email video that i took with ipad camera,

[ms.tardaguila]

Is there a trick to get the videos that you email rightside up? One of my friends can't get them at all, another tells me they Are upside down or sideways.
I have already tried putting the home button on the right. Would unlocking the screen have any bearing?update: I tried emailing to my daughter with the buttons in all four positions......she has windows and fir landscape mode(camera facing out) the home button on the right worked! Video was emailed rightside up!
