Re: Edit Assistant, I was learning FCP7...

[Jamie Franklin] " Lay in a video and drag an audio file to a track lets call that one dialogue. Then take another audio file and lay it in underneath...lets call that music. To test your analysis place it further down the track please without anything above it.....
(uhoh! what is it doing?)
Then try and mute that "track" you say exists...

With your video, do the same thing, try and build a 3 track multi layer without anything underneath one of the videos..."

in all fairness, this is all possible in FCPX, minus putting the clip where you want in vertical space (although you can determine the layer order), including having the clips named music and dialogue non destructively. You can mute whole sections, or selected clips, whatever, with a click or two.

It just doesn't work the way you "want" (read, have been forced) to. You can also export multitrack QTs in one pass.

But you know all this, you just don't like it. That's cool.
