Actually there is an issue exporting an embedded AAF greater than 2GB . Avid created a work around for their products. I don’t know if one is required for Automatic Duck.
She has a fairly slow Mac Book Pro with only 8GB of RAM. Might be fine for a small project, but performance will not be good on a feature film. I’m using a MacPro 2013 and performance can be sluggish with ProRes 4444. I’m not even sure if that model MBP has a qualified GPU for Mercury Engine acceleration. Sounds like a textbook case for using proxies to me.
