  AE reading PDF issues…

  Posted by Tom Ma on August 18, 2011 at 11:28 pm

  I have a bunch of PDF’s that I am bringing into AE.

  Problem is they seem to have an alpha channel, which I do not want.

  I can not Interpret footag, ignore alpha, as it fills the matted areas with black.
  Any other option in Interpret footage wont work either.

  Basically I just need the alpha channel ignored in my comps.

  Per haps there is a way to have AE “read” the files differently? (preference?)

  Or an effect i can quickly use to nullify the alpha?

  thanks

  Hi,

  I don’t think it’s really an alpha channel as such, more that PDFs don’t generally include a background, since a white background is usually supplied by the paper when printed. A workaround is just to precomp the PDF and add a white solid behind it, or ask the person who prepared the PDF to add a filled background object, or open the PDF with illustrator and add the background yourself.
