> I just created a movie in an animation program on a alpha channel background. I have imported it into AE8 and know the alpha channel is in the movie.
> I want to activate this alpha channel so that I can see the background. I switched modes at the bottom of AE but I could not get the effect.
> Any advice? I left my notes an manual at home today..
Click the 'show channels' button (three colored circles in a sort of
triangle) and select the Show Alpha Channel from the menu. This will
display the alpha channel, if any, on the footage.
