      I think I've done this, but now, 2 hours before the tech, I am blocking out (v2.2.2).

      I thought with alpha channel movie (PRO RES 4444), I should be able to simply put this movie in layer 1, background on layer 0, both to opaque, and it should just work, but it does not. Changing blending mode to transparent, additive, opaque has no effect.
      Patch

      Urgent help would be much appreciated.
      Thanks.

        set the movie to transparent and layer 1 and the background to layer 0. This should actually work if the movie is really transparent.

          Thanks, @Michel.

          In a hurry I forgot to select RGB±Alpha in AE output module. Your suggestion works after that fix.
