1st step to vine: animatedgif to virtualdub ---> saveas AVI -
  I'll add music here but sometimes I add it in windows movie
  maker 'cause it's easier to use].   [1]1st-to-virtualdub64 k
  it's .5 sec so into windows movie maker [2]avi-to-wmv from
  wndows movie maker to Handbrake to make it MP4 that's apple
  compatible - notice I had to do crop 80 on each side became wmm
  forces 4:3 instead of 1:1 like Vine likes (which is 480x480 or
  780x780 - whatev - it's square). I used to use VineClient at
  this point but they started charging $$ - so it's back to old
  fashioned e-mail O_O to myself, then upload it to Vine. Just a
  few more minute. Love describing my process. I never get to
  describe my process :P [3]wmv-to-handbrake
