  tga+alpha & .mov+alpha mismatch

  Posted by Thiery Roussel on July 23, 2007 at 3:30 pm

  OK…
  I render out lower third to be integrated into FCP. The text has a different opacity than the solid layer below. the fisrt part is animated in, so i render a .mov uncompressed + alpha, and then, a tga+alpha of the still part. But i get a mismatch from the opacity of the text layer in the 2 version export when i joined them in FCP. Is it a differennce between alpha from .tga and .mov. Any ideas…

  I would imagine that’s bound to happen given that the codec in the QT file might treat the alpha a litle differently than the TGA does.

  One way to fix that is to give your QT some tail-end (maybe 1-2 seconds) so that you can cross-dissolve between the QT and the TGA to hide the transition/glitch.

  i’m not sure if this would help… but there are two ways to render a tga file. one, with targa sequence chosen as the ‘format’ in the output settings window. the other way is to set quicktime movie as the ‘format,’ but then click format options and set tga as the compression type.

  i was just thinking that using qt to render the tga file may produce more similar results to the qt animation file.
