hi all,

I am doing a project that needs to have the final product with its dialouges and music on seperate channels. i have to give them a NON project file, preferably beta sp format, tape format or a DVD.

what is the best way to do this with a mac? FCP4.

See if this article helps you out at all:

if you only have dialogue and music tracks, just pan the dialogue all the way to the left and the music all the way to the right.
