To output my AMA edited sequence, I normally just do a Video & Audio mixdown export a Quicktime reference and it's done, but suddenly, Im doing now I'm getting a number of large dropouts where the audio juststops for a second or 2. No patern, but it does show that when it does the audio mixdown it takes minutes to do it, where normally its only a few seconds.
I'm in a 2013 Mac Pro and version 8.5.0
