Well here I am doing another Calisthenics College DVD for and I just used Adobe's Create Multicam Sequence assuming all was well.
Alas no.
Half way through "cutting out the bad bits" (nod to Walter Murch and meaning breaks between acts) when I discover that the audio on Track 2 (which contains the ambient sound of clapping between acts) is not playing.
A quick google and I discover there is no fix for it and all the golden oldie editors out there are saying to use the Manual multicam method. So I've just lost a couple of hours this morning. Thanks Adobe.
