This is really a editing question as well as an audio one but how do you go about the process? As a whole or bit by bit?
I'm leaning towards editing the footage alone scene by scene with just dialogue only then rendering down to do the other audio parts as a whole for the entire film. I have found I like doing all my audio editing in Cubase due to the extensive plug ins and grouping availability plus the handy jogwheel on my audio interface makes life easier. I would do two Cubase projects, one for scoring and one for foley and when they are done I would mix them down and import into sony vegas where I would have 3 audio tracks, one for dialogue, one for score and one for foley and automate there as I see fit.
Is there a better or standard way to go about this? Do you import all the footage and edit the film as a whole then do a render and reimport and start on all the audio or do you import shot footage for one scene at a time in it's own project get that edited and the audio done and rendered then piece all of them together at the end for a final render?
I can see the advantage of doing a footage only scene by scene edit but for scoring and foley I think the levels would be off for each project plus getting overlapping music from scene to scene would be hard.
