Undipped music stem

[mwpmorris1]

I'm trying to clarify exactly what is an "undipped" music stem. Over the past few years I have interpreted it as music without any dips whatsoever - for on-screen dialogue or vo.

However, sometimes when working on mix stems from other dub houses - when recutting or reversioning for international markets I have seen music stems that are dipped for sync but not for vo.

Can anyone give me their interpretations of this?

I can see the sense in dipped for sync/undipped for vo but it seems a bit inflexible to me and would hamper recutting in future. I think it'd also pose problems if the on screen dialogue were to be replaced in a foreign language.

If someone can shed some light on this I'd be most grateful!
