Ran a test with sound designer and confirmed its that old problem… ‘disabled’ clips in Premiere will not show up in an AAF. For that reason, I usually don’t ‘disable’ audio clips, instead I normally set audio levels to zero instead of disabling. Forgot to tell the assistant to do it this way, and getting stung at the end for it!
But, figured out a janky workaround based on your tip about using the ‘Simplify’ menu:
Duplicated my sequence. Selected all clips on the dupe sequence, and selected ‘enable’. This turns all ‘enabled’ clips to ‘disabled’ and vice versa. Essentially, making my dupe sequence an inverted version of my original sequence. Then, used the ‘Simplify’ menu to remove ‘disabled’ clips, thus leaving only the clips which were ‘disabled’ in my original timeline (that have now been ‘enabled’). Now, I can copy that and overwrite it into my original sequence.
Thanks for the brainstorm, def beats doing it all clip by clip!
