  Swapping Alpha Channel

  Posted by Ho Kim on November 6, 2009 at 11:44 am

  HI…I have one question to ask about switching alpha channel information.

  I have one sequence footage which has Alpha Channel, and the other one doesn’t have.

  Is there any way that I can swap the Alpha channel to the one which doens;t have alpha channel on it? I need to export that data to fill some gap information to my personal work.

  Thank you Creative.net for such a great help all the times.

  From KIM.

  Hi, maybe the effect >> channel >> channel combiner, and then select use 2nd Layer, and from alpha to alpha.
  Hope it helps.

  Or you could dupe the one that has it and use that duplicate as the alpha matte?

  Reality? What did you make it?
