Hello Dave,
thank you for the answer, this is right.
the second movie has a alpha.
my problem with the effect_movie rendered in ae.
is that i use trapcode_particular and i can only see the
effect when there is a background-layer ( colored-layer, layer with picture-information ) beneath it.
so i can not produce a alpha only for the particulars.
do you know a trick, with that i can produce a alpha for the particulars ?
thanx
