  Difference keying and matte pulling

  Posted by Lorraine Collard on May 7, 2010 at 10:39 pm

  Hi All,

  Can anyone point me in the direction of a good tutorial, preferably video, on Difference keying. I am familiar with chroma keying but have been told to learn this technique to help my studies. I understand it is taking the two pieces of footage, and producing the difference between them. Can anyone help, in fact can anyone point me to any tutorials on pulling mattes too, any dvds etc.

  Thanks you for any help offered.

  thanks Lorraine

  Thanks for your help Dave, I have since tried this in both programs and have to say that fusion did a slightly better job in this case, however, like you said, this technique is rarely going to satisfy and I can now understand why.

  many thanks, Lorraine
