I'm cutting a low budget spot shot that's delivering on BetaSP (mono mix, on both tracks).
We don't have the money for an audio mix and I don't have Protools. If I export to 10 bit uncompressed Quicktime, will the audio track mix down from FCP acceptably for the Beta transfer? Would they need a separate sound track?
What are "their" audio requirements? "They" usually have spec sheets that indicate what the audio and video requirements need to be. No, exporting will not magically mix the audio properly for you. You have to do this manually. Just like making a QT movie doesn't magically color correct and make the footage broadcast legal.
