Hah... I was going to take offence to that (I've spent some time in both camps) but if I'm really honest, thinking back to some other video folk I've spoken to, I suspect you're probably right.
Sticking my neck out here - On SUPER SUPER low budget quickie jobs (which I usually try to avoid, but there have been occasions where bills have to be paid) where I've had to do both video & audio at once in Final Cut Pro, I have doubled tracks to increase gain on low-level source. FCP only allows a (IIRC) 12dB gain boost on clips, so when I'm under the hammer it can be faster to do a quick dupe rather than export, process offline, reimport and sync.
But I reiterate, that's only for quick + dirty all-in-one sessions. I would never EVER do that if I were planning to export the session.
