  Yet another alpha channel question…

  Posted by Jakob Steen on January 26, 2010 at 1:42 am

  I have read alot of the posts regarding problems exporting alpha channels and importing them into after effects…

  Right now its very basic… (by the way I am using version 11.5)
  I just have a cube – nothing else – and I want to export it with an alpha channel and put the cube on top of another clip in after effects.

  Here’s what I do exactly!

  Go to render settings – save tab

  Choose quicktime movie

  Choose the ANIMATION compression, and millions of colors +

  Check alpha channel

  Go to “MAKE PREVIEW”

  In options I ensure that the ANIMATION compression and millions of colors + is indeed selected

  Then I hit ok.

  Then it renders out and I place the file into After Effects – and I dont even get to choose how after effects should handle the file. I cannot even go to “interpret footage” and change the settings of the alpha, because its greyed out.

  What am I doing wrong?????

  Is there some secret way of rendering when its alpha or whats code I have to break!

  I am going insane!

  I would appreciate any ideas!

  Thanks in advance

  There was recently a post about this EXACT thing. I will save you the time of having to look for it:

  Make Preview does not render your project, it makes a preview….so it does not include the alpha.

  You need to render to picture viewer to render it out.

  Hope that helps.
