I'm curious as to how much of our location extras (wild tracks, AMBs etc.) actually get used. When I'm working post we usually get the OMFs and spot/edit accordingly. It's not always easy to get the production sound files and even if I did, I wouldn't know what is what without also getting a copy of a production sound report (which I never have). I'm sure it's different on big budget projects, but it seems very rare to see a full AMB track in an OMF, and only a few added FX stuff that often doesn't sound like it's from location.
This is just based from my very-ultra low budget experience, I'm just wondering if more professional projects incorporate more production sound extras.
Thanks!
