Uploading videos onto facebook, but the vid is sideways??

[sgv_jester]

Hi guys I recorded a video on my mt4g onto facebook successfully. However, when i replay the video that is on my facebook, its sideways and I have to turn my head left to watch it. How can I make the video upright? Preferrably a solution to the problem instead of always editing the video to turn it up right, but i'll take any help. thanks guys
