-It’s the system drive that is 511Gb with 400Gb free.
-I’m not sure how big the file will be. It’s coming from a timeline that’s 18 minutes long through quicktime conversion into prores 422.
“3) Have you tried exporting a self contained QT at current settings first, then using that as your master to compress to another codec?”
-I think that’s what I’m trying by going through Quicktime conversion then jumping to Compressor, right?

I’m attempting to do QT conversion again to a non-system drive that has 2.12Tb of 3Tb free. It seems to be going faster, fingers crossed it works.
