Hello,
  
  i have filmed a short movie with my iphone 4 in a longitudinal way, so when i added it to my computer the movie was really messed up, black blanks on each side of the screen, and a very thin video frame
  
  how can i make it fit on the screen? i don't care if it loses its quality
  
  please help me, and thanks in advance
