Hi, this is my first forum post so be gentle with me

I am trying to convert a 1min20sec clip of myself playing guitar that I would like to upload to Google video. This requires the clip to be in MPEG 4 format.

I have d/loaded a couple of trial converter programs but every time the conversion is done, only the top half of my clip is shown - not the whole frame size that I get when playing back AVI.

Is it something I am doing wrong? I am a Pinnicle Sudio 9.4.3 user.
