This is for you sound-heads out there that routinely (or even not-so-routinely) deal with full deliverables for audio post.
The client is asking for full splits - VO, On-camera, Nat, Music, etc, etc... This is routine. Old hat. You can do a layback in you sleep. Heck! Layback time is a chance to sleep! (That's a joke.) The layback is done, the files are made, exported and zipped for delivery. Send. Client is notified, and you go home for the night.
The next morning your inbox is flooded and you have 4 increasingly angry voicemails from the producer. There are drop-outs in your music stem, there's a missing line in the VO split, and the short-version files are all 30 seconds short. Darn. Must have made a misplaced key-command....
So, the question: What is your QC process for standard audio deliverables? (I'm assuming proper session organization and layback routing....Not really talking about that. I'm thinking about review technique.) How do you "double-check" your work? Talk to me.
